Q

[ Definition ]

Displacement

A

the distance between an objects initial and final positions

Q

[ Definition ]

Velocity

A

the speed of something in a given direction

Q

[ Definition ]

Acceleration

A

the rate of change of velocity per unit of time

Q

[ Equation ]

Displacement

A

displacement = final position - initial position

Typical units: meters, kilometers, feet, etc.

Q

[ Equation ]

Velocity

A

velocity = displacement/time

Typical units: m/s, k/m, mph.

Q

[ Equation ]

Acceleration

A

acceleration = velocity/time

Typical units: m/s^2.

Q

The distance an object travels will always be…

A

equal to or greater than the magnitude of the displacement of the object.
