Forces
Define what forces are
a force is defined as a push or pull
Define what energy is
Energy is the ability to do work or produce heat, existing in various forms such as kinetic, potential, thermal, and chemical energy.
Define what simples are
Simple machines are mechanical devices that use a force to do valuable work by changing the direction or magnitude of the force. They have a simple mechanism accompanied by no or very little motion. For example, a pair of scissors is a simple machine that can easily cut through paper.
List the different types of forces
List the different types of energy
Mechanical Energy, Thermal Energy, Nuclear Energy, Chemical Energy, Electromagnetic Energy, Sonic Energy, Gravitational Energy, Kinetic Energy, Potential Energy, Ionization Energy
The inclined plane, lever, wedge, wheel and axle, pulley, and screw.
Define what gravitational forces are
Gravitational force is the force that attracts two bodies toward each other.
Can energy be created or destroyed?
Energy cannot be created or destroyed. This principle is known as the Law of Conservation of Energy. It can only change forms, like from chemical energy in food to kinetic energy when you move.
What are simple machines used for?
Simple machines are fundamental devices that help us perform work more efficiently by modifying the direction or magnitude of a force.
