Potential energy is stored energy that an object has because of its position, shape, or configuration. It can be converted into kinetic energy when conditions change.
What is potential energy?
Potential energy is stored energy associated with an object's position or condition. Common examples include gravitational potential energy and elastic potential energy.
Gravitational potential energy formula
Gravitational potential energy is calculated using PE = mgh, where mass, gravitational acceleration, and height determine stored energy.
Elastic potential energy formula
Elastic potential energy is stored in stretched or compressed objects. The formula PE = ½kx² uses spring constant and displacement.
How to calculate potential energy
Identify the correct formula, convert values into SI units, and substitute the values to calculate potential energy.
Potential energy vs kinetic energy
Potential energy is stored energy due to position, while kinetic energy is energy of motion. Energy can transfer between these forms.
Common potential energy mistakes
Common mistakes include incorrect units, confusing mass with weight, and using the wrong energy formula.
