Force & Newton' Laws of Motion 4 of 4

What would cause the diver to experience a greater acceleration? (faster upward speed)

• The diver should apply a greater downward force

• The diver should apply a smaller downward force

Which of Newton's Laws is represented in this image?

• First Law - object wants to keep on keeping on

• Second Law - greater the force the greater the acceleration

• Third Law - action - reaction forces

Which answer does NOT explain why a bowling ball eventually stops moving?

• Gravity exerts a downward force on the ball.

• The friction of the floor applies a resistance force to the bowling ball.

• The back wall of the lane applies an unbalanced force to the bowling ball.

• The person rolling the bowling ball is not very strong.

Why is it dangerous to stop suddenly in front of a large vehicle?

• Newton's 1st Law - The large object wants to keep moving

• Newton's 2nd Law - The greater the mass the greater the force needed to slow it down

• Newton's 3rd Law - The large truck exerts a large force

What forces act on the rocket to launch it into space?

• gasses push down and out of rocket, rocket is pushed up into the air

• Gravity is pushing down on the rocket and the ground pushes upwards

• The engine is pushing down and the exhaust pushes up.

Newton's First Law is also known as the law of inertia - which is NOT an example of the first law?

• Car slams on the breaks and dog from back seat flies into the front seat.

• You are on an amusement park ride and you get pushed back into your seat when the ride starts

• You are jumping from a boat to the boat ramp and the boat moves away from the

• At first, when the school bus makes a hard turn to the left, you move right

Which law is "BEST" represented by this image?

• First Law - heavier cart has more inertia

• Second Law - the greater the mass the greater the force needed to accelerate the object.

• Third Law - sorry, just can't make this one work. Third law is equal and opposite. This diagram doesn't show that. :)

If the same force is applied, which ball will have a greater acceleration: bowling ball or a baseball?

• Both will have the same.

• The baseball because it has a smaller mass

• The bowling ball because it has a greater mass
