Average speed the total distance traveled by an object over a total amount of time
Balanced force equal and opposite forces on an object that result in no change in position, direction, or motion
Constant speed when an objectâ€™s speed remains unchanged
Displacement how far an object has moved from its original position; the difference between the final and initial positions
Kinetic energy energy of motion
Potential energy stored energy of an object because of its position or shape
Unbalanced force unequal forces on an object that may result in a change in position, direction, or motion
direction a line leading to a place or point
Inclined plane a simple machine for elevating objects
Force influence that results in motion, stress, etc. when applied
Graph a visual representation of the relations between quantities
Newton (N) SI unit of forces
Position the particular part of space occupied by something
Relative motion calculation of the motion of an object with regard to some other moving object.
