Mass of a body and its speed are needed to calculate kinetic energy.

Kinetic energy of an object = mv2/2

This formula is useful only when object's speed is much less than speed of light.

To calculate kinetic energy, you need to know the mass of the object and its velocity. The formula for kinetic energy is KE = 1/2 * m * v^2, where KE is kinetic energy, m is mass, and v is velocity.

The object's mass, and its speed. Both are used in the formula for kinetic energy, whether you use the basic formula, or the more complicated relativistic formula.

### How factors are used to calculate the kinetic energy of an object?

KE = (1/2)mv2 where m = mass (in kilograms), and v = velocity (in meters/second) this gives you the kinetic energy in units of Joules

### You can calculate kinetic energy by using the equation what?

The equation to calculate kinetic energy is: KE = 0.5 * m * v^2, where KE is the kinetic energy, m is the mass of the object, and v is its velocity.

### What is the energy of moment?

A moving object has both moment, and kinetic energy. You can't calculate one from the other; it is possible for two objects to have the same moment, and different amounts of kinetic energy. This is because the moment is proportional to the velocity, while kinetic energy is proportional to the square of the speed.
