Forces Quiz

Students conducted an investigation in which they rolled a bicycle wheel on different ground surfaces. What is a testable question that the students could be investigating?

• How does friction of ground surfaces affect how a bicycle wheel rolls? 

• 
  How does the size of a bicycle wheel affect how it is rolled on different ground surfaces? 

• 
  How does gravity affect how a bicycle wheel rolls? 

• 
  How do different types of bicycle wheels affect how they roll on different ground surfaces?

Students are investigating and observing the “domino effect.” They set dominoes up in an intricate design and then push one domino at the end of the design. What will students observe in this investigation?

• The domino that is pushed will fall over because of the force of gravity, leaving the other dominoes to remain standing. 

• The domino that is pushed will fall over because of the force of friction, knocking into other dominoes and pushing them down. 

• The domino that is pushed will fall over because of the force of gravity, knocking into other dominoes and causing gravity to pull them down one after the other. 

• The domino that is pushed will fall over because of the force of magnetism, leaving the other dominoes to remain standing.

What investigation will help a lab team test the effect of friction on an object?

• Drop a ball from different heights.

• Roll different toy cars across a smooth table.

• Use a magnet to move a paper clip across a table.

• Roll a toy car across smooth and rough surfaces.

A student enters his classroom to see the setup for an investigation.  There are two ramps at different heights and a toy car. What question is the class most likely trying to answer?

• How does the height of a ramp affect the distance a toy car will travel?

• How does a toy car affect the angle of a ramp?

• How does friction affect the distance a toy car will travel?
