Kinetic energy is the energy possessed by an object due to its motion. It is directly proportional to the square of the object's velocity (v) and is expressed in joules (J). Mathematically, kinetic energy (T) can be calculated as:
where:
T is the kinetic energy in joules
m is the mass of the object in kilograms (kg)
v is the velocity of the object in meters per second (m/s)
A simple example of kinetic energy is a ball rolling on the ground. If a ball has a mass of 0.1 kg and is rolling at a velocity of 10 m/s, its kinetic energy would be:
The kinetic energy of an object is directly related to its ability to do work. The more kinetic energy an object has, the more work it can do.
For example, if a ball is thrown in the air, it will have more kinetic energy than if it is dropped from the same height. This is because the ball has more time to slow down and reach its maximum velocity before it hits the ground
