Force and Motion Review

Front

What information does Lola need to gather to measure her average speed when biking around her neighborhood?

Back

distance traveled and total time traveled

Front

Which of the following statements about the car's motion is true?

• The total time for the car trip was 50 minutes.
• The car returned to where it had started the trip at the end of the trip.
• The car did not slow down during the trip.
• The car did not travel at a constant speed during the entire trip.

Back

The car did not travel at a constant speed during the entire trip.

Front

Which statement BEST describes the motion of the cars?

Back

Cars 1 and 3 have variable speeds, whereas Car 2 has a constant speed.

Front

Which of the following correctly describes the object's motion?

Back

The object is moving with constant velocity.

Front

Why would a bouncy ball go slower moving away from the ground?

Back

because the ball must move against the force of Earth's gravitational field on the way up

Front

Why does the book stay still on the desk?

Back

The forces acting on the book are balanced.

Front

Why does an apple fall from a tree?

Back

the gravitational attraction between the apple and Earth

Front

A teacher throws two balls with the same force. The first ball has a mass of 0.1 kg, and the second ball has a mass of 0.5 kg. Which statement BEST describes the results?

Back

The first ball has a smaller mass, so it will have greater acceleration than the second ball.

Front

Which argument is supported by the results of the investigation?

Back

The acceleration of an object is proportional to the force applied to the object but not the mass of it.

Front

An object that is traveling east at a constant rate has

Back

speed and velocity, but no acceleration.
