Newton's Laws of Motion Quiz

Newton's first law states that:

• Every object remains in its state of rest unless acted upon by an external force

• Force equals mass times acceleration

• Action equals reaction

• Momentum is conserved in a collision

What is inertia?

• The tendency of an object to resist motion

• The rate of change of velocity

• The force required to move an object

• The resistance offered by air

Newton's second law gives the relationship between:

• Force and mass

• Force and acceleration

• Force, mass, and acceleration

• Mass and weight

The SI unit of force is:

• Kilogram

• Newton

• Joule

• Watt

Newton's third law of motion states that:

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

• Force equals mass times acceleration

• Objects in motion stay in motion

• Energy is conserved

The force required to accelerate a 10 kg object at 2 m/s^2 is:

• 5 N

• 20 N

• 50 N

• 10 N

Which of the following is not a correct application of Newton's third law?

• A rocket propels upward

• A swimmer pushes water backward to move forward

• A car accelerates on a smooth surface

• A stationary object remains at rest

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

• It accelerates

• It decelerates

• It remains in uniform motion or at rest

• It changes its direction

The force of gravity acting on a 1 kg mass is:

• 9.8 N

• 1 N

• 98 N

• 0.98 N

A force is said to be balanced when:

• It produces no acceleration in an object

• It causes an object to move

• It changes the shape of an object

• It produces maximum velocity
