What is kinetic energy?
Energy stored by a moving object.
What is the equation for kinetic energy?
E_{k}=\frac12mv^2
What is gravitational potential energy?
The energy stored of an object at height from a gravitational field.
What is the equation for gravitational potential energy?
E_{p}=mgh
What happens to an objects gravitational potential energy when it falls (assuming there is no air resistance)?
It is converted into kinetic energy.
What is elastic potential energy?
Energy stored in a reversibly stretched or compressed object.
What does the elastic potential equation work up to?
The limit of proportionality.
What is the equation for elastic potential energy?
E_{e}=\frac12ke^2
