What does Velocity measure?

• measures how quickly an object moves

• measures an object’s speed and direction

• measures the rate of change of velocity

What is the definition of Acceleration?

• The rate of change of velocity of an object with respect to time.

What does Acceleration measure?

• measures how quickly an object moves

• measures an object’s speed and direction

• measures the rate of change of velocity

What is the relationship between Speed, Velocity, and Acceleration?

• Speed is the rate of change of distance, velocity is speed with direction, and acceleration is the rate of change of velocity.

• Speed is a vector quantity, velocity is a scalar quantity, and acceleration is the rate of change of speed.

• Speed, velocity, and acceleration are all scalar quantities.
