Newton's Laws Quiz

What is force?

• A push that causes a change in an object's motion

• A push or a pull that causes an object to move, stop, or change direction

• A pull that causes an object to move, stop, or change direct

• How fast something is moving

Which scientist came up with the 3 laws of motion ?

• Albert Einstein

• Charles Darwin

• Indiana Jones

• Isaac Newton

What is the net force?

• 800 N

• 600 N

• 400 N

• 400 N down

Which best describes Newton's 1st law?

• Law of force

• Law of action-reaction

Use the diagram to answer the question.

Brennan is traveling in a car at a constant speed. He quickly applies his brakes and stops to avoid an accident. Brennan’s body continues to move forward and is stopped by the seat belt. Why?

• an object in motion remains in motion unless acted on by an unbalanced force

• for every action there is an opposite equal reaction

• when mass increases a greater force is needed to accelerate the object

• the law of gravity

Which law says f = m∘a

• Newton's first law

• Newton's second law

• Newton's third law

• Newton's fourth law

Which formula would you use to find the acceleration of a bike rider with a mass of 50kg who pushes off with a force of 25 Newtons.

• f = ma

• V= d/t

• y=mx + b

A cart was pushed with a force of 50 N, if its mass is around 3.4 kg, how much was the acceleration produced? F= MA

• 14.7 m/s²

• 53 m/s²

• 0.068 m/s²

• 170 m/s²

If a 10 kilogram object accelerates suddenly at 15 m/s², how much force was applied to the object? F=MA

• 150 Newtons

• 15 Newtons

• 150 kilograms

• 100 kilograms

If the man pushes with an equal amount of force, which object will accelerate more?

• Car because it has more mass

• Lawnmower because it has less mass

• Car because it has less mass

• Lawnmower because it has more mass
