Newton's Laws of Motion

When a marble is pulled back and released on a Newton's Cradle, the marble on the opposite side moves in the opposite direction. This is due to...

• Newton's First Law of Motion

• Newton's Second Law of Motion

• Newton's Third Law of Motion

• Newton's Law of Inertia

When trying to load a moving truck with furniture, the movers tried shouting at the boxes to get on the truck. The boxes did not move. This is due to...

• Newton's Second Law of Motion

• Newton's Third Law of Motion

• Newton's Law of Action and Reaction

You are able to stop a soccer ball from rolling down a hill. When a train (with much more mass) rolls down the same hill, you find it slightly harder to stop. This is due to...

• Newton's Second Law of Motion

• Newton's Third Law of Motion

• Newton's Fourth Law of Motion

Two people are pushing a cart up a ramp. Person 1 pushes with a force of 10 N, and person 2 pushes with a force of 15 N. If they are pushing the cart together, what is the net force?

• 10 N

• 15 N

• 150 N

• 25 N

Which formula for Newton's Second Law is correct?

• F = m x a

• F = m / a

• m = a / F

• a = m / F

Whenever two surfaces come into contact, this is the force that results from them touching.

• Inertia

• Balanced forces

• Friction

• Unbalanced forces

You shove two boxes with the same amount of force. You notice that Box 1 moves with 1/4 the acceleration of Box 2. This must mean that...

• The mass of Box 1 is double the mass of Box 2.

• The mass of Box 1 is quadruple the mass of Box 2.

• The mass of Box 1 is 1/2 the mass of Box 2.

• The mass of Box 1 is 1/4 the mass of Box 2.

What is the force on an object if it has a mass of 5 kg and accelerates at 5 m/s/s?

• 10 N

• 10 m/s/s

• 25 N

• 25 kg

Bob and Susan are standing on identical skateboards. Bob is taller and has more mass than Susan. Bob pushes Susan away with 10 N of force. If Bob had pushed Susan with 30 N of force, what force would Bob be pushed away with?

• 30 N

• 10 N

• 20 N

• 3 N

You notice during a game of tug of war that even though both teams are pulling in opposite directions, the rope is still moving to the right. This is due to...

• Friction

• Gravity

• Balanced forces

• Unbalanced forces
