Study Notes

Work and Energy in Physics

The formula for work in physics is W = F × d, where W is work, F is force, and d is displacement.
Units of energy include Joule (J), calorie (cal), and kilowatt-hour (kWh).

Kinetic Energy

Kinetic energy is the energy of motion, and an example of it is the energy of a moving car or a rolling ball.

Potential Energy

Potential energy is the energy of position or stored energy, and it increases as an object is lifted to a higher height.
As an object falls, its potential energy decreases.

Work and Energy Concepts

Work is the transfer of energy from one object to another, and it is a measure of the amount of energy transferred.
Energy can be transferred from one form to another, such as from potential energy to kinetic energy.
