Acceleration Reading Quiz

What are three ways an object can accelerate?

• 1. By speeding up, maintaining constant velocity, or changing direction

• 1. By speeding up, slowing down, or changing direction

• 1. By maintaining constant velocity, slowing down, or changing direction

• 1. By speeding up, slowing down, or maintaining constant velocity

What is the difference between average acceleration and instantaneous acceleration?

• 1. Average acceleration is the change in displacement divided by the elapsed time; instantaneous acceleration is the acceleration at a given point in time.

• 1. Average acceleration is acceleration at a given point in time; instantaneous acceleration is the change in displacement divided by the elapsed time.

• 1. Average acceleration is the change in velocity divided by the elapsed time; instantaneous acceleration is acceleration at a given point in time.

• 1. Average acceleration is acceleration at a given point in time; instantaneous acceleration is the change in velocity divided by the elapsed time.
