Newton developed this law of motion has significant mathematical and physical elucidation that are needed to understand the motion of objects in our universe. Newton introduced the three laws in his book Philosophiae naturalis principia mathematica (Mathematical Principles of Natural Philosophy), which is generally referred to as the Principia. He also introduced his theory of universal gravitation, thus laying down the entire foundation of classical mechanics in one volume in 1687. These laws define the motion changes, specifically the way in which those changes in motion are related to force and mass. There are three laws of motion which were introduced by Sir Isaac Newton which are Newton’s First Law , Newton’s Second Law and Newton’s*…show more content…*

Newton 's First Law of Motion states that a force must act upon it in order for the motion of an object to change . This is a concept which generally called as inertia. This law also states that if the net force which is the vector sum of all forces acting on an object is zero, then the velocity of the object is constant. Velocity is a vector quantity which indicates both the object 's speed and the direction of its motion. Hence, the statement that states the object 's velocity is constant is a statement that both its speed and the direction of its motion are constant. This is also known as uniform motion which means if an object continues to do whatever it happens to be doing unless a force is exerted upon it. If it is at rest, it continues in a state of rest and if an object is moving, it continues to move without changing its speed. Changes in motion must be foisted against the tendency of an object to retain its state of motion. In the absence of net forces, a moving object tends to move along a straight line path indefinitely.

That is, a particle initially at rest or in uniform motion in the preferential frame Φ continues in that state unless compelled by forces to change it.”

APPLICATIONS FROM NEWTON’S FIRST LAW OF MOTION.

a) AIRPLANES. When the airplane flying at a constant altitude , aircraft holds constant airspeed if thrust and drag are equal. If thrust is increased , the aircraft accelerates and the airspeed increases. After that , the drag depends on airspeed , thus the drag increases. When drag is again equal to thrust , the aircraft no longer accelerates but holds a new , higher , and constant airspeed. This explains that every object persists in its state of rest or uniform motion in a straight line unless it is compelled to change that state by forces on it.

b) CAR. Newton’s First Law also known as Law Of Inertia. Inertia explains why you move forward in your seat when a car stops suddenly. When the car stops , inertia keeps you moving forward. A force such as the pull of a seat belt , is required to change

When the airplane is in level flight at a constant speed, the force of the thrust is just enough to counteract the aerodynamic drag. Moving air can also generate forces in a different direction from the flow. The force that keeps an airplane from falling is called lift. Lift is generated by an aircraft wing.

Burning fuel caused the rocket to move upward, giving the rocket an equal and opposite reaction. The second law has to do with the mass of the rocket. The more weight an object has, the more force is needed to move it.

The Magnitude and Direction of Centripetal Acceleration It has been established that the direction of the centripetal acceleration is always towards the center of the circular path. This way the acceleration is entirely perpendicular to the velocity vector. (If it had a parallel component, then there would be a change in speed, which is no longer centripetal acceleration.)

1833 Words | 8 PagesSo in theory to steer, it requires a change of direction in both the velocity and acceleration. An airplane steers while it is in the air via a system of flaps on the wings, called control surfaces. Depending on how the flaps are oriented, this determines the direction that the plane will travel. For example, when the pilot wants to turn the plane to the left, he will activate a control surface on the left wing and point the flap downward. This will increase the drag on the left wing while the right wing stays the same, therefore causing the plane to turn left.

The second law expresses that a body in movement stays in movement unless followed up on by an outside power.

The mass is the mass of the cart and passengers, whereas gravity serves as the force acting on it. The passengers are able to feel the force, this changes as the acceleration starts to slow down. The cart starts to slow down because of the friction.

## Carburetor Case Study

1335 Words | 6 PagesThe pipe is in the form of a venturi it narrows in section and then widens again, causing the airflow to increase in speed in the narrowest part. Below the venturi is a butterfly valve called the throttle valve a rotating disc that can be turned end-on to the airflow, so as to hardly restrict the flow at all, or can be rotated so that it (almost) completely blocks the flow of air. This valve controls the flow of air through the carburetor throat and thus the quantity of air/fuel mixture the system will deliver, thereby regulating engine power and speed. The throttle is connected, usually through a cable or a mechanical linkage of rods and joints or rarely by pneumatic link, to the accelerator pedal on a car or the equivalent control on other vehicles or

Mass is the measurement of how resistant an object is to being accelerated. Newton’s first law of motion states that an object in motion will stay in motion and an object at rest will stay in rest unless a net external force acts upon it. This law means that an object moving at a certain velocity will maintain that same velocity unless an outside acts upon it.

The principles of equivalence, these principles of equivalence are divided into two categories the weak one which states that the local effects of motion in a curved space (gravity provides a curved space according to the general theory of relativity) are not different from those of an accelerated observer in at space. And the strong one states that the consequence of any local experiment (whether it is a gravitational or not) in a freely falling laboratory
