Which of the following explains the money on the elbow grab trick?

When you remove your elbow the money wants to remain at rest until gravity pulls it down.

When you move your elbow it adds a balanced force on the money so they stay still.

Moving your elbow places an unbalanced force on the money in an equal & opposite direction.

A truck and a car are both broke down on Eagle Parkway. Which one would require the least amount of force to push out of the way and why?

The car, because it has less mass

The car, because it has smaller tires

The truck, because it has more mass

The truck, because it has bigger tires

Which of the following are an example of Newton's 3rd Law of Action-Reaction?

jumping forward off a skateboard that then goes backward

a rocket taking off by pushing down on Earth to go up

a bowling ball requires more force to throw than a basketball

bus riders moving forward in the seat after the bus stops suddenly

If the mass of an object does not change, what would be the effect of pushing with a greater force?

The acceleration would increase.

The acceleration would decrease.

The acceleration would not change.

What do you look for when trying to solve a problem that involves force, mass or acceleration?

If there are Newtons, divide putting the Newtons in the calculator first.

If there are Newtons, multiply putting the Newtons in the calculator first.

If there are Newtons, divide putting the Newtons in the calculator second.

If there are Newtons, multiply putting the Newtons in the calculator second.

Which of the examples is NOT a correct statement?

A volleyball drops on the other side of the net after hitting the net with a balanced force.

Increasing the amount of friction will slow an object down.

Increasing the force on an object will cause the object to accelerate.

Heavier objects require more force to change their motion than lighter objects.
