Emma and her friends are racing toy cars on a race track. Emma can hear their wheels on the track. All the cars have the same mass. Each car is racing at a constant speed. Stop watches are used to time the cars. Emma records the results of the race in a table.

Using the data in the table as evidence, Emma made the following claim: The red car traveled with the greatest kinetic energy. Is Emma’s claim supported by the evidence?

• No, because the blue car traveled for the longest time.

• No, because the green car had the fastest speed

• Yes, because the red car traveled the farthest distance

• Yes, because the red car had the fastest speed.

Use evidence in the picture to explain the energy transfer shown.

• The toasted bread is evidence that electrical energy is

  transferred to the toaster, where electrical energy is then

  transformed into thermal energy.

• The plugged-in toaster is evidence that electrical energy is

  transferred to the toaster, where electrical energy is then

  transformed into light energy.

• The toasted bread is evidence that chemical energy is

  transferred to the toaster, where chemical energy is then

  transformed into thermal energy.

• The plugged-in toaster is evidence that chemical energy is

  transferred to the toaster, where chemical energy is then

  transformed into electrical energy.
