Multiple Choice

You are driving to a birthday party with the cake sitting in the passenger's seat. You slam on your brakes to avoid hitting a deer. This causes the cake to splatter all over your dashboard and the floor of the passenger's side. Which of Newton's Laws best explains why this happens?

​Example question:

​How much force is required to accelerate a 2kg mass at 3m/s²?

​

force = mass x acceleration

force = 2 x 3

force = 6 N​

​

How much force is required to accelerate a 10kg mass at 3m/s²?

​

Force = 10 x 3

force = 30 N​

Multiple Choice

10. A ball rolls down from the top of a grassy hill, reaches the bottom of the hill, continues to roll, and then starts to slow down and comes to a stop. What forces caused this ball's motion?

• Frictional force caused the ball to roll down the hill, but air resistance caused the ball to slow down and stop.

• Magnetic force caused the ball to roll down the hill, but gravity caused the ball to slow down and stop.

• The force of the hill caused the ball to roll down it, but gravity caused the ball to slow down and stop.

• Gravity caused the ball to roll down the hill, but frictional force caused the ball to slow down and stop.
