Newton's Laws Form Corrections

A remote-control car has a mass of 1.5kg. Its electric motor accelerates the car at 6m/s2. What force does the motor provide?

2000 N of force cause an elevator to accelerate at 2 m/s2. What is the mass of the elevator?

A bow applies 25 N of force to an arrow with a mass of 2 kg. What is the acceleration of the arrow?

For the next 9 questions, you will identify the correct Newton's law that relates to each statement. Do you understand?

• Yes
• No

Forces occur in action-reaction pairs.

• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law

Balanced forces are equal in size but act in opposite directions.

• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law

The inertia of an object depends on its mass; the greater the mass, the greater the inertia.

• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law

Acceleration of an object depends on the mass of the object and the force exerted on the object.

• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law

When the same amount of force is applied to two objects with different masses, the object with the greater mass has less acceleration.

• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law

Inertia is the tendency of an object to resist a change in motion.

• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law
