Motion - a change in position over time, Position - the location of an object relative to a reference point, Reference Point - used to describe an object or individual's position in comparison to another location, Speed - a mesure of how far something moved (distance) divided by the give amount of time it took to travel that distance , Average Speed - Calculated by distance divided by time formula and often expressed as m/s, km/s, or mph, Velocity - speed in a specific direction , Acceleration - the change in velocity over time. This can mean that an object changes speed, direction, or both, Force - a push or pull on an object, Net Force - the combination of all forces acting on an object, Balanced Forces - if both forces are going in opposite directions, you subtract the forces. They do not change the motion. The net force is 0., Unbalanced Forces - cause a change in motion. They have a net force greater than 0., Friction - a contact force that opposes motion when two objects are touching, Gravity - pulls people and objects towards the earth, Magnets - the force can be felt at a distance before they are even touching. The force can also be felt as they repel., Newton's First Law of Motion - the law of inertia. It states that an object at rest will remain at rest, and an object in motion will remain in motion, unless acted on by an unbalanced force, Newton's Second Law of Motion - the acceleration of an object depends on the mass of the object and the amount of force applied, Force Formula - mass times acceleration, Newton's Third Law of Motion - whenever one object exerts force on a second object, the second object exerts an equal and opposite force on the first. (action-reaction), this graph represents an object moving at a CONSTANT PACE, this graph represents an object AT REST or MOTIONLESS, This graph represents an object that is in POSITIVE ACCELERATION, This graph represents an object that is in NEGATIVE ACCELERATION, this graph represents an object RETURNING TO IT'S STARTING POINT,
