What is Kinetic Energy and Momentum

We go through the forces and motions with these fundamentals of physics!

Any object that is said to have motion has kinetic energy, which is defined as half the mass of an object multiplied by its velocity squared.

It quantifies the work that the object could do as a result of its motion. Rolling a bowling ball, driving a car, or a glass falling from a table are all examples of kinetic energy at work, with each possessing a specific amount at any given point. The faster or more massive a body is, the more kinetic energy it will subsequently have. An object at rest is said to have potential energy, which is converted to kinetic energy when it actually begins to move.

The kinetic energy can then be converted into other forms such as thermal or sound energy when it is acted on by another force, colliding with another object or accelerating for example.

Kinetic Energy and MomentumAs an object accelerates it gathers momentum, which is defined as mass x velocity. The driver of a moving car must apply brakes to stop the car as it has gained momentum and will continue to move forwards unless it is acted on by another force such as friction or contact with another body. Like kinetic energy, the greater the mass or velocity of an object, the greater its momentum. A force acting on a moving object will change its momentum, such as when two cars collide; the result of the collision will see each object with a new amount of momentum, which will depend on their initial mass and velocity.

Kinetic energy = (mass of object x (velocity of object)2)/2

Momentum = mass of object x velocity of object
