Newton's Laws of Motion Quiz

What does Newton's First Law of Motion state?

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

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

• 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.

• The acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to its mass.

Which law is also known as the law of inertia?

• First Law of Motion

• Second Law of Motion

• Third Law of Motion

• None of the above

Newton's Second Law of Motion can be mathematically expressed as:

• Both A and B

• None of the above

What does Newton's Third Law of Motion imply?

• Objects in motion tend to stay in motion.

• Acceleration is produced when a force acts on a mass.

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

• The amount of inertia an object has depends on its mass.

Inertia is a property that describes:

• The speed of an object.

• The tendency of an object to resist changes in its state of motion.

• The amount of matter in an object.

• The gravitational pull on an object.

According to Newton's Second Law, if the mass of an object is constant, the acceleration is directly proportional to:

• The net force acting on the object.

• The velocity of the object.

• The distance traveled by the object.

• The time taken by the object to stop.

• A rocket launching into space.

• An apple falling from a tree.

• A book resting on a table.

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

• Kilogram (kg)

• Meter (m)

• Newton (N)

• Joule (J)

If the force acting on an object doubles, what happens to the acceleration, assuming mass remains constant?

• It halves.

• It remains the same.

• It doubles.

• It quadruples.

What does it mean when we say that force and acceleration are directly proportional to each other?

• Increasing the force will decrease the acceleration.

• Increasing the force will not affect the acceleration.

• Increasing the force will increase the acceleration.

• There is no relationship between force and acceleration.
