BMST - Basic Math and Science Newton's Laws of Motion Questions and Answers

Question 1

A passenger in a car feels pressed back into their seat as the car accelerates forward. This sensation is best explained by which of Newton's laws?

Accepted Answer

Newton's First Law (Inertia)

Answer

Newton's Second Law (F=ma)

Answer

Newton's Third Law (Action-Reaction)

Answer

The Law of Universal Gravitation

Question 2

According to Newton's Second Law of Motion, if a constant net force is applied to two objects, one with a mass of 10 kg and the other with a mass of 20 kg, which statement is true?

Accepted Answer

The 10 kg object will accelerate twice as fast as the 20 kg object.

Answer

Both objects will have the same acceleration.

Answer

The 20 kg object will accelerate twice as fast as the 10 kg object.

Answer

The acceleration of both objects is independent of their mass.

Question 3

A rocket propels itself forward in the vacuum of space by expelling hot gases from its engine. This is a classic example of which principle?

Accepted Answer

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

Answer

The relationship between force, mass, and acceleration.

Answer

An object in motion tends to stay in motion.

Answer

The force of gravity acting on the rocket.

Question 4

Which of the following objects possesses the greatest inertia?

Accepted Answer

A large, stationary cargo truck

Answer

A baseball moving at 90 mph

Answer

A feather floating in the air

Answer

A bowling ball resting on a rack

Question 5

If the net force acting on an object with constant mass is doubled, what is the effect on the object's acceleration?

Accepted Answer

It is doubled.

Answer

It is quadrupled.

Answer

It is halved.

Answer

It remains the same.

Question 6

Which of the following scenarios is the best example of a Newton's Third Law action-reaction pair?

Accepted Answer

A swimmer pushing water backward with their hands, and the water pushing the swimmer forward.

Answer

The force of gravity pulling a book down and the normal force of a table pushing the book up.

Answer

A car accelerating forward and the force of air resistance pushing against it.

Answer

The Earth pulling on the Moon and the Sun pulling on the Earth.
