Newton's Laws of Motion

Front

Two objects are connected by a rope over a pulley. According to Newton's Second Law of Motion, the masses will start to move if the mass of object 1 is greater than the mass of object 2.

Back

mass of object 1 is greater than the mass of object 2

Front

Which statement best explains Newton's Third Law of Motion?

Back

For every action there is an equal and opposite reaction.

Front

Which is the best example of Newton's First Law of Motion?

Back

A soccer ball remains motionless until it is kicked by a player.

Front

According to Newton's 1st Law, when will a motionless object start to move?

Back

an unbalanced force is applied to the object

Front

As the wheels of a train push down on the track, the track pushes back against the wheels. Which of Newton's laws is used to explain these forces?

Back

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

Front

Which example best explains Newton's Third Law of Motion?

Back

When you sit on a chair, your body exerts a downward force on the surface of the chair, while the chair exerts an equal and upward force on your body.

Front

A truck that is travelling at a constant speed is carrying some boxes. If the truck comes to a sudden stop, what will most likely happen to the boxes?

Back

They will slide toward the front of the truck.

Front

A student throws a ball against a wall. Which statement best explains what is happening?

Back

The force from the wall on the ball is equal and opposite to the force from the ball on the wall.

Front

Object X has twice the mass of Object Y. Both objects are accelerating at the same rate. Which statement best describes the motions of Object X and Object Y? Options: Object X is travelling at twice the speed as Object Y., Object X is travelling at half the speed as Object Y., Object X requires twice the force to accelerate at the same rate as Object Y., Object X requires half the force to accelerate at the same rate as Object Y.

Back

Object X requires twice the force to accelerate at the same rate as Object Y.

Front

A person steps out of the boat and onto the dock. As the person moves forward onto the dock, the boat moves backward. Which statement best describes the backward motion of the boat as the person steps forward? Options: For every action there is an equal and opposite reaction., Every mass exerts a force on every other mass., An object at rest tends to stay at rest., Friction opposes the motion of an object.

Back

For every action there is an equal and opposite reaction.
