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.

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.

Definition and Mathematics of Work. Calculating the Amount of Work Done by Forces. Potential Energy. Kinetic Energy. Mechanical Energy. Power. Kinetic energy is the energy of motion. An object that has motion - whether it is vertical or horizontal motion - has kinetic energy.
Calculate the kinetic energy of a particle given its mass and its velocity or momentum Evaluate the kinetic energy of a body, relative to different frames of reference It’s plausible to suppose that the greater the velocity of a body, the greater effect it could have on other bodies.
