So the formula for kinetic energy is that it's equal to 1/2 times the mass of the object, times the magnitude of its velocity squared, or another way to think about it, its speed squared. And so given this formula, pause the video and see if you can calculate the kinetic energy for each of these running backs.

You can calculate the amount of energy in an object’s kinetic energy store ( \bold {E_k}) using the following formula: E_k = \dfrac {1} {2} m v^2. m= the mass of the object in kilograms \text { (kg)} v= the velocity of the object in metres per second \text { (m/s)}.

To calculate kinetic energy, we follow the reasoning outlined above and begin by finding the work done, W , by a force, F , in a simple example. Consider a box of mass m being pushed through a distance d along a surface by a force parallel to that surface.
