Acceleration
A change in the velocity(speed, direction or both) of a body
Density
An object's mass divided by its volume; a measure of how many particles are packed together into a certain amount of space
Force
A pull or push that is applied to an object
Gravity
A force that exists between any two objects that have mass
Magnitude
Size of ground movement caused by seismic waves due to energy released
Mass
The amount of matter in an object
Motion
A change in the position of an object compared to another object
Speed
Distance traveled per unit of time
Thrust
A reaction force that pushes an object forward
Velocity
The speed and direction of moving objects
Frame of Reference
An item against which the motion of an object can be measured
Friction
A force that opposes the motion of a body across a surface or through a gas or liquid
Weight
The force of gravity on an object
Free Fall
Downward motion with only the force of gravity
Potential Energy
The amount of energy that is stored in an object; energy that an object has because of its position relative to other objects
Kinetic Energy
The energy an object has due to its motion
Newton's 1st Law
An object will not change its motion unless a force acts on it
Newton's 2nd Law
The force on an object is equal to its mass times its acceleration
Newton's 3rd Law
There is an equal and opposite reaction for every action
