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.
