Newton's Laws Quiz

What does Newton's First Law of Motion state?

• An object in motion will change its velocity if a force acts upon it.

• An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

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

• The force on an object is equal to its mass times its acceleration.

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

• A ball rolling down a hill speeds up.

• A book lying on a table remains at rest.

• A rocket launching off into space.

• A car slowing down as it approaches a stop sign.

What does Newton's Second Law of Motion describe?

• The relationship between an object's mass, its acceleration, and the applied force.

• The necessity of an unbalanced force to change an object's motion.

• The equal and opposite reaction for every action.

• The natural state of objects to remain at rest or in uniform motion.

According to Newton's Second Law of Motion, what happens when the same force is applied to two objects of different masses?

• Both objects will experience the same acceleration.

• The object with the larger mass will have a greater acceleration.

• The object with the smaller mass will have a greater acceleration.

• The objects will not move since the forces cancel each other out.

If two forces act in opposite directions on an object, how do you determine the net force on the object?

• Add the two forces together.

• Subtract the smaller force from the larger force.

• Multiply the two forces.

• Divide the larger force by the smaller force.

What happens to an object if the net force acting on it is zero?

• It will start moving in the direction of the applied force.

• It will increase its speed.

• It will change its direction of motion.

• It will not change its state of motion.
