The study of the motion of objects.
The describing of the motion of objects using words, diagrams, graphs, numbers, and equations.
A quantity that is described by a numerical value alone.
A quantity that is fully described by both a numerical value and a direction.
A scalar quantity that refers to how much ground an object has covered during its motion.
A vector quantity that refers to how far out of place an object is; the object's overall change in position.
A scalar quantity that refers to how fast an object is moving.
A vector quantity that refers to the rate at which an object changes position.
How to get average speed
Distance traveled divided by the time of travel.
How to get average velocity
Position divided by time equals displacement divided by time.
The speed at any given instant in time.
The average of all instantaneous speeds, found simply by a distance over time ratio.
A vector quantity that refers to the rate at which an object changes its velocity. As long as the object's velocity is changing, the object is accelerating.
When the velocity of an object is changing at a constant speed.
How to get acceleration
Acceleration equals velocity divided by time.
