Exploring Newton's Laws of Motion

What does Newton's First Law of Motion state about an object at rest?

• It will remain at rest forever.

• It will start moving on its own.

• It will remain at rest unless acted on by a force.

• It will move in a circular path.

If a box is on a surface and all forces acting on it are balanced, what will happen to the box?

• It will remain at rest.

• It will rotate.

• It will start moving.

• It will accelerate upwards.

What is momentum defined as?

• Mass times acceleration

• Mass times velocity

• Force times distance

• Velocity divided by time

What does the impulse-momentum theorem state?

• Impulse is equal to mass times acceleration.

• Impulse is equal to velocity divided by time.

• Impulse is equal to the change in momentum.

• Impulse is equal to force times distance.

According to Newton's Third Law, what happens when you apply a force on an object?

• The object does not react.

• The object accelerates indefinitely.

• The object applies an equal and opposite force back.

• The object moves in the same direction.
