Force and Motion Review

A student used 12 newtons of force to push a box 4 meters down the driveway. Using the formula, how much work, measured in joules (J), did they do to move the box? Work = force x distance

• 3 J

• 8 J

• 16 J

• 48 J

What will happen to the mass of a ball if it is moved from Earth to the Moon?

• The mass will increase

• The mass will remain the same

• The mass will decrease

• The mass will not exist

Which term refers to the tendency of an object to maintain its state of motion?

• inertia
• friction
• acceleration
• momentum

What is the difference between speed and velocity?

• Speed and velocity are the same thing.
• Velocity is the rate at which an object covers distance, while speed is the rate at which an object covers distance in a specific direction.
• Velocity is always greater than zero, but speed can be greater or less than zero.

• Speed is the rate at which an object covers distance, while velocity is the rate at which an object covers distance in a specific direction.

Which scenario best demonstrates an example of Newton's first law of motion?

• An object in motion will eventually come to a stop on its own.
• A rocket lifts off from a launch pad.

• A car passenger moves forward when a car suddenly stops.

• A shopping cart accelerates when it is pushed. 

What force, in newtons, is required to keep the object in the picture below at rest?

• 0 N

• 12 N

• 18 N

• 48 N

A force of 6.0 N is applied horizontally to a 3.0 kg crate initially at rest on a horizontal frictionless surface. After the crate is pushed for 1.5 seconds, it has a velocity of 3.0 m/s. Does this support Newton's second law of motion, that force equals mass times acceleration? Explain.

• No, because the mass and the velocity of the crate are equal.

• Yes, because the mass and the velocity of the crate are equal.

• No, because the acceleration of the crate is 2.0 m/s2.

• Yes, because the acceleration of the crate is 2.0 m/s2.
