SBA Review #2 Part 3

• The force of friction is the same on each block.

• The force of friction causes the speed of each block to increase.

• The force of gravity causes all the blocks to move at the same speed.

• The force of gravity is greater than the force of friction on all the blocks.

One morning, Ryan noticed there were tiny drops of water on the grass as he walked to school. That afternoon, he did not see any drops of water on the grass when he returned home. Which of the following best explains what happened to the drops of water?

• The heat from the air caused the water drops to boil.

• The air cooled the water and caused the drops to freeze.

• The Sun heated the water and caused the drops to evaporate.

• The energy from the Sun caused the water drops to condense.

Delilah followed these steps of an investigation:

• Collect five objects made of different types of metal.

• Place them on a large laboratory table.

• Touch each metal object with a magnet and lift slowly.

• Record observations.

Which of the following statements is Delilah most likely testing?

• All types of metal are attracted to magnets.

• Each magnet can lift the metal object to the same height.

• Larger magnets can pick up heavier metal objects than smaller magnets can.

• Heavier metal objects are more attracted to magnets than lighter metal objects are.
