Physics Quiz

You throw a tennis ball and a basketball with the same amount of force. Which ball will likely move farther?

• The tennis ball will move further.

• The basketball will move further.

• It depends on the direction of the throw.

• Both balls will travel the same distance.

Which of the following statements accurately describes the forces acting on the bridge?

• The forces are balanced, so the bridge is stable.

• The forces are unbalanced, so the bridge is stable.

• The forces from the left are greater than the forces from the right.

• The forces from the top are greater than the forces from the bottom.

A cup is resting on a kitchen counter. Which statement best describes the forces acting on the cup?

• The forces are equal and acting in the same direction.

• The forces are equal and acting in opposite directions.

• The forces are unequal and acting in the same direction.

• The forces are unequal and acting in opposite directions.

Which type of force resists motion?

• friction

• gravity

• pull

• push

What occurs when two magnets are brought closer to each other?

• The magnetic force will repel the magnets.

• The magnetic force will attract the magnets.

• The gravitational force will repel the magnets.

• The gravitational force will attract the magnets.

A boy pulled a sled across the snow and moved it 2 feet in 5 seconds. He then asked a friend to help him pull the sled. How does the combined force change the motion of the sled?

• The combined force will change the direction of the motion of the sled.

• The combined force will create more friction and stop the motion of the sled.

• The combined force will make the sled move the same distance, but more slowly.

• The combined force will make the sled move the same distance, but more quickly.

Jasmine pushes a sled on ice with a force of 2 Newtons (N). The sled glides smoothly across the ice. Jasmine then applies another push of 2 Newtons (N) to the sled, while at the same time, Alex pulls the sled with a force of 3 Newtons (N) in the same direction. Which of the following best explains the outcome?

• The sled will glide at about its original speed due to increased resistance.

• The sled will slow down because a pull counteracts a push.

• The sled will glide at more than twice its original speed because the push and pull are in the same direction.

• The sled will glide faster than its original speed, but less than twice as fast due to increased resistance with speed.

The diagram illustrates a basic electrical circuit. It features a clip composed of an unidentified material. The light bulb illuminates brightly when the circuit is closed. What is the clip most likely made of?

• plastic

• ceramic

• aluminum

• paper

What happens to the beam from a flashlight when you direct it straight at a standard mirror?

• The beam will reflect upward to the ceiling.

• The beam will reflect downward to the floor.

• The beam will reflect back towards the flashlight.

• The beam will pass through the mirror.
