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?
Newton's First Law (Inertia)
Newton's Second Law (Net force = mass x acceleration)
Newton's Third Law (Action/Reaction)
Law of Universal Gravitation

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

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.
