A lamp sitting on a table is demonstrating Newton's ___ Law.

• 1st

• 2nd

• 3rd

• 4th

A ______ is a push or pull on an object.

• force

• speed

• acceleration

• velocity

Newton's 2nd Law says the acceleration of an object depends on its _______ and ______. (Choose two answers)

• force or applied force

• weight

• gravity

• mass

What will be the effect on the boy in the picture if the driver stops quickly?

• Because of inertia he will remain in the same position.

• He will be pushed back into the car seat.

• He will move from one side of the car seat to the other.

• He will move forward pressing against the seatbelt.

Sitting at the top of a steep hill on a roller coaster (not moving), is an example of:

• Acceleration

• Inertia

• Speed

• Velocity

A magician pulls a tablecloth out from under dishes and glasses on a table without disturbing them.

• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law
• None of them

Pushing a child on a swing is easier than pushing an adult on the same swing, because the adult has more inertia.

• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law
• None of them

Pushing a child on a swing is easier than pushing an adult on the same swing, because the adult has more inertia.

A person not wearing a seatbelt flies through a car window when someone slams on the breaks because the person’s body wants to remain in continuous motion even when the car stops.

• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law
• None of them

An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

• Newton's 2nd Law
• Newton's 3rd Law
