Newton's 3rd Law states that for ever action there is an equal and opposite ________.

• reaction

• satisfaction

• fraction

• transaction

A ______ is a push or pull on an object.

• force

• speed

• acceleration

• velocity

A force that causes an object to slow down when it touches another object is _________.

• gravity

• friction

• inertia

• Newton

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

• force or applied force

• weight

• gravity

• mass

Which of Newton’s Laws explains a rocket’s movement during launch?

• Newton's First Law of Motion

• Newton's Second Law of Motion

• Newton's Third Law of Motion

• Newton's Fourth Law of Motion

A picture is hanging on a wall and does not move.

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

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

Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).

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

This law is often called "the law of inertia."

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