Definitions: Energy - Energy is the ability to do work. Force - A force is a push or a pull that acts on an object. When a force causes an object to move a distance in the same direction as the force then Work = Force x Distance. Gravity - The attraction between two objects due to their mass. Each planent has a different gravity. Gravity on earth is 9.8N/km Kinetic energy- Kinetic energy s the energy to an object in motion. Mass - The amount of matter in an object. Potential energy - Potential energy is stored energy. Thermal Energy - Thermal energy is when friction does work on an object and some of its energy becomes thermal energy. Also it is the total energy of the moving particles in a substance. Weight - Is the force of gravity acting upon an object. Work - Work is done when a force causes something to move and energy is transfered.
Units:
Energy or Work is measured in Joules (J)
Force is measured in Newtons (N)
Distance is measured in Meters (m)
Interesting Facts: The term "gravity" comes from "gravitas" meaning heavy in Latin. The term "kinetic" comes from "kinema" meaning motion in Greek.
