Motion Acceleration Quiz

What is acceleration?

• Acceleration is the force acting on an object

• Acceleration is the rate of change of velocity with respect to time.

• Acceleration is the distance traveled by an object

• Acceleration is the speed of an object

How is acceleration calculated?

• acceleration = final velocity + initial velocity

• acceleration = final velocity / time

• acceleration = initial velocity / time

• acceleration = (final velocity - initial velocity) / time

What are the units of acceleration?

• m/s^2

• kg

• cm/s

• m

• km/h

Explain the difference between positive and negative acceleration.

• Positive acceleration results in slowing down, while negative acceleration results in speeding up.

• Positive acceleration results in decelerating, while negative acceleration results in accelerating.

• Positive acceleration results in maintaining speed, while negative acceleration results in changing direction.

• Positive acceleration results in speeding up, while negative acceleration results in slowing down.

Provide an example of an object experiencing acceleration.

• person standing still on the sidewalk

• plane flying at a constant speed

• bicycle slowing down on a hill

• car speeding up on a highway
