Distance | a scalar quantity of how far you travel along a path from A to B. Path Dependent |
Displacement | a vector quantity of how far apart two parts are in space. |
Velocity | a vector quantity that describes the change in distance divided by the change in time. |
Speed | a scalar quantity that describes a velocity without the direction. |
Acceleration | a vector quantity that describes the change in velocity divided by the change in time. |
Frame of Reference | a viewpoint that can be used to describe moving objects. |
Projectile Motion | a type of motion where an object follows a curved path due to gravitational force acting on it in the y-direction only. |
Linear Motion | a type of motion where the object follows a straight-line path. |
Harmonic Motion | a type of motion where the object oscillates back-forth in a wave pattern. |
Freefall | a type of motion where the object has only the force of gravity acting on it. |
Equation for Average Speed | = total distance / total time |
Equation for Velocity | = distance / time |
Equation for Acceleration | = (final velocity - starting velocity) / time |
SI Unit for Displacement | meter (m) |
SI Unit for Time | second (s) |
SI Unit for Velocity | meter per second (m/s) |
SI Unit for Acceleration | meter per second squared (m/s^2 or m/s/s) |
