how to derive the formula of kinetic energy. Note that mass is a scalar and can therefore be factored out. To derive the equation I used a system where a particle starts at rest and then has a constant force applied to it so that it accelerates with a constant acceleration.
Work done by gravity path independent Next lesson. To derive the equation I used a system where a particle starts at rest and then has a constant force applied to it so that it accelerates with a constant acceleration. He reasoned roughly as follows.
Assuming potential energy is constant Work is equal to the change in kinetic energy.
In physics a moving particle is said to have more energy than the particle at rest. To get the next equation derive an expression for the displacement of the object during the time interval Dt. This expresses the equation in the slope-intercept form of a line y mx b. The formula for kinetic energy is.
