Motion - defined as the change of position over time, Reference Point - is a place or object used for comparison to determine if something is moving, Frame of Reference - is how the object moved based on the reference point you choose., Speed - Distance traveled per unit of time, Velocity - Directional speed of an object in motion, Speed Formula - s = d/t, Friction - the resistance that one surface or object encounters when moving over another, Gravity - Example: Pull force, Unbalanced - Vector quantities that do NOT equal out in how strong they are in an opposite/or the same direction. Or equal in size and opposite directions., Balanced - Vector quantities that equal out in how strong they are in opposite directions. Or equal in size and opposite directions. (Examples: at rest or constant speed), Net Force - the overall resulting force on an object, Newtons - What is used to measure force, Potential Energy - the energy that an object has when it is not moving and it is based on its position and location, Kinetic Energy - the energy that an object has when it is moving and it is based on its speed and velocity, Law of conservation of energy - Energy is not created or destroyed, on transformed/transfered,
