Start the timer at the instant the ball is released from your hands (make sure stopwatch is zeroed before each trial) 4. Stop stopwatch the instant the ball hits the ground 5. Record results in suitable table 6.
Physics Lab Report Name – Shaurya A Singhal I.D – 13229 Grade – 12 Investigating the effect of the angle of incidence on the diameter of a Crater formed by a falling object Introduction When a bob is dropped into sand, a circular crater is formed due to the impact of the ball. The size of the crater varies with numerous factors, Mass of falling object Angle of incidence Velocity of object Rigidity and Tensile Strength of surface on which object falls Background Theory When a high-speed object strikes a surface, it produces an enormous amount of energy. This is called kinetic energy because it is caused by motion. The amount of energy produced in this way depends on the mass of the impacting object and the velocity with which it strikes the surface: KE = ½mv2, where m is the mass of the object and v is its impact velocity. Asteroids hitting Earth have impact velocities from about 11 to 25 kilometres per
One scientific theory related to this experiment is the Magnus Effect. The Magnus Effect is in action when the ball is pushed from high to low pressure, which makes it curve (The Physics of Kicking a Soccer Ball). During the Magnus Effect, the passing air is moving the same direction as the surface of contact on one side of the ball. Since the person in this experiment kicked with their left foot, the ball curved to the right a little because the air moved over the ball faster on the left side, causing less pressure on the other side of the ball. All of this air movement is what makes the ball slant in a different direction.
Construction Challenge #4 Explain what the challenge was… The challenge was to make, with your team, a 30 inch cantilever beam with 16 plastic straw, 5 of the straw wrappers, and 15 centimeters of tape. Each team was allowed to use scissors and a hole punch to put together the straws. Then, Mr. Milhous placed the beam 24 inches off the table 6 inches on the table. After that, he moved a marshmallow on the cantilever beam until the beam could no longer support the marshmallow. The team points were determined by measuring the distance of the marshmallow off the table minus the deflection of the straws.
This is because vectors can be used to describe things with magnitude and direction. A volleyball's displacement has both of magnitude (distance) and direction. The arms extended out can be modeled as planes, and by looking at how different angles affect the rebound trajectory of the volleyball, I can manipulate the angle of the plane in relation to the bumper to get the right direction of reflection towards the setter. The Problem How do I angle myself in relation to the setter when bumping a spike? Volleyball Basics My exploration will start with investigating the basics of volleyball.
At long distances, two nuclei repel each other due to the positive protons and the electrostatic force. However, if two nuclei were to be brought close enough the electrostatic repulsion can be overcome by the attractive force of the nuclear force, which becomes stronger at nearer distances. In the diagram below, the electrostatic force between the positively charged nuclei is repulsive, but when the separation is small enough, the attractive nuclear forces is stronger. As a result, the requirement for fusion reaction to occur is that the two nuclei are brought close together for enough time for the nuclear force to
Hot Air Balloon Analysis In the duration of this project there were many factors that needed to be kept into consideration. The most important was the laws of gas, because the hot air balloon needed to be be constructed enough to withstand the air and have enough room for the hot air particles to move making the balloon have a successful flight. Due to the hot air particles move as a faster rate making then collide to each other which causes the balloon to have enough energy to take flight. While actually launching the ballon I began to see the balloon that did take flight and those who did not. In the beginning of the class launch many of the hot air balloon were successful.
The strings pack quite a gravitational pull on anything that passes through or gets near them, this might cause the cosmic string to travel incredible speed and ease from time dilation. When two cosmic strings are pulled together, it is possible to distort space-time creating Closed time-like curve, wherein the space and time returns exactly the same as it was in the past. The interaction between two cosmic strings could propel itself into the past it will bend around the cosmic strings. In simple words, as stated by the theory of relativity, once the cosmic string moves in a light speed, time will drift slower for the cosmic string relative to its surroundings. A closed loop of cosmic string drifts in a more standard way.
Therefore, the object is accelerating and this acceleration is known as centripetal acceleration (ac=v²/r, ac is centripetal acceleration, v is velocity and r is radius). Centripetal acceleration also have another name, G-force, are due to two factors one is the speed of the carriage and the other is the radius of the circle (how curved the track is). This acceleration is due to the unbalanced force called centripetal force (Fc=mv²/r, where Fc is centripetal force, m is mass, v is velocity and r is radius). Greater speed will result in a greater acceleration and therefore a greater net force, on the other hand smaller radius means a smaller acceleration and net force required. Both centripetal force and centripetal acceleration are towards the centre of the
When P and S waves reached the surface of the Earth they get converted into long waves that travel along the surface, vibrating horizontally at right angle to the direction of the waves are called “Love Leaves” or “Rayleigh” waves as they also travel like a sea waves. The most violent shocks and subsequent destruction is caused by the L
