Define: Speed, Velocity, and Acceleration.

• Speed is the rate of change of distance, Velocity is speed with direction, Acceleration is the rate of change of velocity.

• Speed is the rate of change of velocity, Velocity is speed without direction, Acceleration is the rate of change of distance.

• Speed is the rate of change of time, Velocity is speed with direction, Acceleration is the rate of change of speed.

• Speed is the rate of change of distance, Velocity is speed without direction, Acceleration is the rate of change of time.

An object is consistently traveling 20 m/s around a curve. Is the object's speed constant?

• Yes, because the speed is not changing.

• No, because the speed is increasing.

• No, because the speed is decreasing.

• Yes, because the object is accelerating.

What is the difference between distance and displacement?

• Distance is a vector quantity, displacement is scalar.

• Distance is the total path traveled, displacement is the shortest path.

• Distance is measured in meters, displacement in seconds.

• Distance is always positive, displacement is always negative.
