Question

define kinetic energy devirne and equation expression​

Answer 1

The kinetic energy of an object is the energy an object has due to its motion. The formula for kinetic energy is: KE=1/2 mv^2 , where m is the object's mass and v is its velocity.

This is expressed in the formula ∆KE=Fd. You can then use algebra or calculus to derive the kinetic energy equation

Answer 2

Answer:

In physics, the kinetic energy (KE) of an object is the energy that it possesses due to its motion.[1] It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest.
