S8p3 (Speed, Velocity, Acceleration)

Front

What is the definition of speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s) or feet per second (ft/s).

Front

What is the definition of velocity?

Back

Velocity is the speed of an object in a particular direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, which can occur when an object speeds up, slows down, or changes direction.

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).
