Change in movement
what is acceleration
a push or pull that can make an object speed up, slow down, or change direction
what is force
the force that acts in the opposite direction when you slide one object over another
what is friction
The force by which a planet or other body draws objects towards its center
what is gravity
how fast an object is moving and how much mass that object has
what is momentum
Forces that act on a object without causing a change in the objects motion
what is balanced forces
the tendency of an object to remain at rest or in motion unless it is acted on by a force
what is inertia
forces that change an objects motion changes
what is unbalanced forces
this occurs when a force is applied to an object and the object moves
what is work
rate at which something moves
what is speed
any force that requires contact to occur
what is contact force
force which acts on an object without coming physically in contact with it
what is noncontact force
