Centripetal Force and Centrifugal Force The component of force that acts on a body in curvilinear motion which coordinates towards the focal point of curvature or axis of rotation can be defined as Centripetal force. Whereas, centrifugal force is defined as the apparent force, equivalent and inverse to the centripetal force, draws a turning body away from the focal point of rotation, which is caused by the inertia of the body. CONCEPTS These forces have different concepts where one of the forces has the

Friction is a force that helps to determine the winner in a game of tug-o-war. I know this because friction is the only force that can cause the teams and rope to move to either side. Without any friction there would be no movement to each side happening in the system, thus no one would win. If one team has more frictional force then they will win; this is a system and anything that happens to one side happens to the other. When team 1 pulls and team 2 doesn’t, team 1 will win because there is no

PHYSICS DISCUSSION QUESTIONS Would your results be the same if you had used the duct tape side of the block instead of the wood? Explain. The results would not be the same since duct tape has a different friction from wood. This is because wood has a more uneven and rough texture, while duct tape is smoother. If all 4 sides of the block (ignoring the 2 ends of the block) were the SAME material, would it matter which side you placed the block on? Explain why or why not. No, it wouldn’t matter

characteristics of the minor characters highlight the flaws in the type of person Macbeth is. Duncan is a foil because of his role as king, the role that Macbeth desired and sought after. Lennox, Ross, Mentieth, Simward and the nobles are foils because they are forces that worked and conspired against him. Even Lady Macbeth and Lady Macduff oppose and present foils because of Lady Macbeth’s actions, although the same as Macbeth, happen at different times in the play and Lady Macduff being a nurturing and kindhearted

the poem, Owen had demonstrated that disabled veterans are not properly being treated, because they are different from the normal standards of an individual. Although Wilfred Owen’s poem “Disabled” addressed the lack of veteran care for returning

Rough draft Today Shakespeare is known as the large factor of most literary readings in mainstream culture. While all things that seem to be paranormal are usually eliminated by the realities of other know beings many aspiring authors that want their books to be looked at and studied just as any other writer, would tell you staying clear of ghost and, goblins ,witches and demons, for the being that these topics are known to be a sure sign of a low blow fiction novel. But the plays of Shakespeare

Within Ralph Ellison’s novel Invisible Man, he uses many literary devices - most prominently symbolism. He includes the descriptions of objects to help his audience grow a better understanding of the things that the invisible man (IM) goes through, and to create a sort of pathway to connect with him. Some of the more significant objects that he use are: Mary Rambo’s racist (broken) coin bank, the idea of IM identifying as Brer Rabbit, as well as IM’s briefcase which he brought along with him everywhere

sanity that could be left, it is like the fire had burned up any of the sane part in left in Jack. After this Jack starts to fight for total dominance, the harsh elements that occur on the island cause the deuteriation of some type of aspect in a normal society. The first fire causes the disappearance of the first child. These harsh elements in the setting seem to one by one bleach out any remaining ethics.   The overall aspect of the novel The Lord of the Flies completes a transition through the

It is hard to tell what is true and not true in a novel, especially when the author says, “Often the crazy stuff is true and the normal stuff isn't, because the normal stuff is necessary to make you believe the truly incredible craziness” (68). The character Mary Anne Bell was too crazy for this novel though. The most unrealistic characters in The Things They Carried is Mary Anne Bell because she went to the war as a civilian not a soldier, embodies the theme loss of innocence, and there are other

The lift and drag characteristics of NACA 0012, 1408, 2412, and 4412 airfoils are characterized using a 6” by 6” subsonic wind tunnel equipped with a force balance. The axial and normal forces on the airfoil are measured at angles of attack ranging from -8° to 28° and used to determine lift and drag forces. Lift, drag, and drag polar curves are generated using experimental data. Lift coefficients are found to increase linearly with increasing angle of attack up to the critical angle of attack. Drag

law states that the real effect of a force is always to change the speed of a body, rather than just set it moving, as was previously thought. It also meant that whenever a body was not acted on by any force, it will keep on moving in a straight line at the same speed. What happens to a body when a force does act on it is given by Newton’s second law which states that the body will accelerate, or change its speed, at a rate that is proportional to the force. In addition to his laws of motion,

Results: Qualitative Observation:     While standing in the elevator at rest, the individual felt normal, meaning it was the same feeling as standing in a regular room. As the elevator accelerated upwards going to a higher floor, the person’s body felt slightly heavier and as if the elevator floor was pushing against her feet. However, as the elevator was cruising, she felt that she was back to normal again as she did standing in the lab. As the elevator approached its destination, it began to decelerate

Self Actualization Equals a Superior Society in “A&P” As a naive young man only beginning to understand the consequences of his judgement, Sammy reflects many teenagers during their pivotal stage of life. A person’s journey to understanding themselves, their thoughts, and their actions is a never ending winding road. He or she may experience numerous sticky situations and moments of trial, defeat, and self doubt before learning their place in society. In the early 1960s, the feminist movement was

are different from the principles of the normal aircraft (in which the wings are fixed). For the normal aircraft, there is only one component or one source of the airflow passing through the aerofoil which is the airflow that caused by the forward motion of the aircraft. It acts in the direction that is parallel to the flight path but in the opposite direction. In this case, the force that acts perpendicular to the airflow will be equal to the lift force. However, for the ornithopters, there are

this equation relates to outside forces such as air resistance. When the roller coaster ride begins the forces acting on it are the force of gravity, normal force, and dissipative forces (which is the work done externally on the cart). The force of gravity and the normal force both have no effect on the work done on the carts. This is due to the fact that the force of gravity is internal and the normal force is perpendicular to the motion. However, the dissipative forces do. Through this, a small amount

For the block A: Here the net downward (along the incline) force acting on the block Fa = m*g*sinθ + m*aT (component of weight and psedo force) So Fa = 1*10*sin30 + 1*5 = 10 N Also the normal reaction on the block will be Ra = m*g*cosθ = 1*10*cos30 = 8.66 N Hence the maximum frictional force possible on the block fmax(a) = μs(a) * Ra = 0.4*8.66 = 3.46 N < fa Hence the block A will move down the incline with acceleration aA = (fa - fk(a))/m = (10 - 0.2*8.66)/1 = 8.27 m/s2 (This acceleration

The element needed is called elastic collision. “An elastic collision is defined as one in which both conservation of momentum and conservation of kinetic energy are observed. This implies that there is no dissipative force acting during the collision and that all of the kinetic energy of the objects before the collision is still in the form of kinetic energy afterward” (Nave, Elastic and Inelastic Collisions). Using this element of physics, it is known that after a collision

Operational Lift Force and Drag Force In Ambient Conditions Author Names: Dr V.N. Bartaria (H.O.D Mechanical engineering LNCT Bhopal) Shivani Sharma (B.E. Mechanical engineering Pursuing M.tech) Abstract: It is a fact of common experience that a body in motion through a fluid experiences a resultant force which, in most cases is mainly a resistance to the motion. A class of body exists, However for which the component of the resultant force normal to the direction

In today’s world running, walking and just normal day activities are done with each individual wearing shoes, sandals or some type of foot protection. Now a good portion of individuals would not think about just going barefoot because people would think it hurts our feet or is just not seen as the norm to American living but what people don’t know is that barefoot running is healthier than normal shoe running. Like we talked about in class a good amount of runners that wear shoes, they tend to strike

geometry and joint capsule all combine in a complex manner to produce joint stability. If any of these structures malfunction or disrupted, knee joint instability occurs. These factors are all interdependent and serve the function of both determining normal motion and limiting motion beyond a certain point. JOINT SURFACE The constraints provided by the femoral and tibial joint surfaces are not adequate for functional stability. The distal femur is convex, where as the proximal tibia is partially flat
