Force and Motion

Acceleration the rate at which velocity changes over time; an object accelerates if its speed, direction or both change
Average Speed the total distance traveled divided by the total time taken
Balanced Forces a set of forces on an object that cancel one another out so that there is no overall force on that object; the combined force is the same as zero force; balanced forces will not cause a change in the motion of an object
Displacement the change in position in an object
Force a push or pull exerted on an object in order the change the motion of the object; force has size and direction
Friction a forces that opposes motion between surfaces that are in contact
Inertia the tendency of an object to resist being moved or, if the object is moving, to resist a change in speed or direction
Instantaneous Speed the rate of motion at a particular instant in time
Motion an object's change in position relative to a reference point
Net Force the combination of all the forces acting on an object
Newton's Laws of Motion a series of laws developed by Isaac Newton that describe the relationship between force and motion
Newton the SI unit for force (symbol, N)
Position the location of an object
Reference Point a location to which another location is compared
Speed a measure of how fast something moves; rate of motion
Unbalanced Forces a set of forces exerted on an object that change the motion of that object; the combined force has size and direction; unbalanced forces are needed to make an object start moving, speed up, slow down or change direction
Vector a quantity that has both size and direction
Velocity the speed of an object in a particular direction
Velocity the speed of an object in a particular direction
