Acceleration
Measure of how quickly the velocity of an object changes
Velocity
the speed and direction of an object's motion
Refrence point
The starting point you use to describe the motion or position of an object
motion
the process of changing position
balanced forces
when the net force on an object is 0
unblanced forces
When the net forces acting on an object is not 0
contact force
A push or pull applied by one object to another object that is touching it
gravity
A non contact attractive force that exists between all objects that have mass
force
A push or pull on an object
Interia
The tendency of an object to resist changes in its velocity: weather is motion or motionless
friction
A contact force that resists the sliding motion between two objects that are touching
