Newton's Laws of Motion Quiz (Level 1)

What is inertia?

• The ability of an object to move easily

• The speed at which an object moves

• Resistance of an object to changes in its motion or rest

• The force that causes an object to move

Which of the following statements best describes Newton's First Law of Motion?

• An object at rest will stay at rest, and an object in motion will stay in motion with the same speed and in the same direction, unless acted upon by an external force.

• An object at rest will start moving in the opposite direction if no external force is applied.

• An object at rest will eventually start moving if no external force is applied.

• An object in motion will eventually come to a stop if no external force is applied.

Which of the following is an example of inertia?

• A car accelerating when the gas pedal is released

• A car turning left when the steering wheel is turned right

• A car continuing to move forward after the brakes are applied

• A car stopping immediately after the brakes are applied

What is the law of inertia?

• An object at rest will stay at rest, and an object in motion will stay in motion with a different speed and direction, unless acted upon by an external force.

• An object at rest will stay at rest, and an object in motion will stay in motion with the same speed and direction, unless acted upon by an external force.

• An object at rest will stay at rest, and an object in motion will slow down and eventually stop, unless acted upon by an external force.

• An object at rest will stay at rest, and an object in motion will change its direction, unless acted upon by an external force.

Which of the following is an application of Newton's First Law of Motion?

• A car accelerating from rest.

• A ball rolling down a hill.

• A rocket launching into space.

• A brick wall standing still.

• 1st Law (Inertia)

• 2nd Law (Force=Mass x Acceleration)

• 3rd Law (Action and Reaction)

The SI units for force are...

• Kilograms
• Newtons
• Meters per second
• Pounds

How does Newton’s third law explain how a rocket takes off?

• The rocket’s acceleration is positive, while the gasses acceleration is negative but the direction is the same. 
• The rocket is at rest until ignition.
• The hot gasses move in one direction, while the rocket moves in the opposite direction but with equal force.

For a force on an object there is an equal and opposite force.

• Newton’s first law of motion
• Newton’s second law of motion
• Newton’s third law of motion
