Newton's Laws of Motion Quiz

What is Newton most famously known for, despite it likely being a myth?

• Formulating the laws of motion

• Having an apple fall on his head

• Discovering gravity

• Inventing calculus

According to Newton's first law, what happens to an object if no resultant force acts on it?

• It accelerates

• Its velocity remains constant

• It comes to a stop

• It changes direction

In a tug of war with equal forces on both sides, what is the resultant force?

• 500 Newtons

• 1000 Newtons

• Zero

• 200 Newtons

What does Newton's second law state about the relationship between force and acceleration?

• Force is equal to acceleration divided by mass

• Force is equal to mass times acceleration

• Force is inversely proportional to acceleration

• Force is independent of acceleration

If a car has a mass of 1000 kg and a resultant force of 3000 Newtons is applied, what is its acceleration?

• 0.3 m/s²

• 3 m/s²

• 30 m/s²

• 300 m/s²

What happens to a car when a braking force is applied in addition to drag?

• It accelerates

• It maintains constant speed

• It decelerates

• It moves in the opposite direction

According to Newton's third law, what happens when a book rests on a table?

• The book exerts no force on the table

• The table exerts a force equal to the book's weight

• The book exerts a force less than its weight

• The table exerts a force greater than the book's weight

What is an example of Newton's third law in action?

• A tug of war

• A car accelerating

• A book resting on a table

• A car moving at constant speed

When two ice skaters push off each other, what law explains their movement?

• Law of universal gravitation

• Newton's second law

• Newton's first law

• Newton's third law

What is the key takeaway from Newton's third law?

• Forces are always equal

• Forces only act in one direction

• Forces are independent

• Forces always act in pairs
