Dynamics
is concerned with the forces that affect motion
Displacement
distance and direction of an object's change in position from the starting point.
Distance
How far an object moves
Speed
distance an object travels per unit of time which can be calculated by v = d/t where v = speed, d = distance, and t = time.
Average Speed
total distance that an object travels divided by the total time it takes to travel that distance.
Instantaneous Speed
speed of an object at a given point in time which is constant for an object moving at constant speed and is different at each point in time for an object that is slowing down or speeding up.
Velocity
describes the speed and direction of a moving object.
Acceleration
rate of change of velocity which occurs if an object speeds up, changes direction, or slows down.
Kinematics
the branch concerned with the motions of objects without being concerned with the forces that cause the motion.
