Kinetic energy must always be either zero or a positive value. While velocity can have a positive or negative value, velocity squared is always positive. Kinetic energy is not a vector. So a tennis ball thrown to the right with a velocity of 5 m/s, has the exact same kinetic energy as a tennis ball thrown down with a velocity of 5 m/s.

Kinetic energy is the energy that any object with mass has simply because it is moving. If an object is not moving, it has no kinetic energy. An object's kinetic energy is directly related to its mass. Imagine two objects moving at the same speed. If one object has twice the mass of the other, it will also have twice the kinetic energy.
1. Write the equation. The formula for calculating kinetic energy (KE) is KE = 0.5 x mv2. Here m stands for mass, the measure of how much matter is in an object, and v stands for velocity of the object, or the rate at which the object changes its position.
