Newton’s 3rd Law of Motion 2-1 Scale Review

What is the interaction between two objects called?

• motion

• force

• action force

• reaction force

• mass

How do mass and acceleration affect the motion of objects according to Newton’s second law?

• Mass increases acceleration

• Mass decreases acceleration

• Acceleration increases with mass

• Acceleration is independent of mass

What can be calculated using action-reaction force pairs?

• motion

• force

• action force

• reaction force

• net force

What can be used to predict the outcome of colliding objects?

• Newton's third law of motion

• motion

• force

• action force

• reaction force

How do objects respond to action forces according to Newton’s first law?

• They accelerate

• They remain at rest

• They move at a constant velocity

• They decelerate

What does Newton's third law state about forces?

• For every action, there is an equal and opposite reaction

• Force equals mass times acceleration

• Objects in motion stay in motion unless acted upon by an external force

• Acceleration is produced when a force acts on a mass

How does the gravitational force between two objects change if the distance between them is halved?

• The force is halved

• The force is doubled

• The force increases by four times

• The force decreases by four times

What unit is used to measure force in the International System of Units (SI)?

• Kilogram (kg)

• Meter (m)

• Newton (N)

• Second (s)

What is the effect of increasing the mass of an object on its gravitational pull?

• Increases the gravitational pull

• Decreases the gravitational pull

• No effect on the gravitational pull

• Initially increases then decreases

Which of the following best describes inertia?

• The ability of an object to change its state of motion

• The resistance of any physical object to any change in its velocity

• The rate of change of momentum of an object

• The force applied to bring an object to rest
