5th Force, Motion, and Energy

The box would be easier to move if the surface of the ramp was smoother because there would be less -

• distance to push the box

• mass in the box

• friction opposing the box

• gravity pulling on the box

A student placed his marble game above a stereo speaker. When he turned the speaker on, the marbles shook and some fell to the floor.

WHICH OF THE FOLLOWING STATEMENTS BEST EXPLAINS THE MOTION OF THE MARBLES?

• magnetic energy attracted the marbles

• sound waves cause the marbles to vibrate

• electricity pushed the marbles

• heat caused the marbles to move

• true
• false

Inertia is....

• for every action, there is an equal and opposite reaction
• larger objects take more force to move 
• an object in motion tends to stay in motion unless acted on by an opposite force
• a push that acts in the opposite direction and it slows down.

A student uses a spring scale to pull a 50-gram block horizontally across a wood desk. Then the student pulls the block the same distance across surfaces of carpet, sandpaper, and glass. Which question is this investigation most likely designed to answer? (5.6D)

• How do block of different sizes react to force?

• How do different surfaces affect the amount of force needed to move a block?

• How do blocks affect spring scales?

• How does the mass of a block change when it is pulled across a desk?
