Term | Definition |
Acceleration | Acceleration is the rate at which an objects velocity changes |
Air resistance | Air resistance is a kind of fluid friction, as it flies through the air |
Average speed | Average speed is the total distance and time |
Balanced forces | Forces that cancel each other completely are called balanced forces |
Distance | Distance is the measure of how far it is from one point to another |
Energy | Energy is the ability to do work or cause change |
Force | A force is a push or a pull |
Friction | Friction is a force that occurs when two surfaces rub against each other |
Gravity | Gravity is a force that pulls all objects toward one another |
Kinetic Energy | Kinetic energy is the energy an object has because it is moving |
Mass | Mass is the amount of material, or matter, in an object |
Momentum | Momentum is a property that a moving object has because of its mass and velocity |
Motion | Motion is the process of changing from one position, or place, to another |
Newton's First law of Motion | It states that a moving object will continue to move with the same velocity in a straight line until a large enough force acts on it and changes its motion |
Newton's Second law of Motion | Newton's Second law of Motion shows how force, mass, and acceleration are related |
Newton's Third law of Motion | Newton's Third law of Motion states that for every action, there is an equal and opposite reaction |
Potential Energy | Potential Energy is stored energy |
Speed | Speed is how fast it changes position |
