Energy and Motion

Answer Key - Grade 4 Science Worksheet - Building Confidence

Read the investigation. Write the answer on the line.

1. Read this first

   A ramp and block test

   Sam let a toy car roll down a ramp and crash into a foam block. He used a low, a middle and a high ramp, and measured how far the block was pushed each time.

   Low ramp: 6 cm
   Middle ramp: 15 cm
   High ramp: 28 cm

2. 1.

   What did the tester change to give the car different amounts of energy of motion?

   ramp height
3. 2.

   Which ramp gave the car the most energy of motion?

   high
4. 3.

   Which ramp gave the car the least energy of motion?

   low
5. 4.

   Which gives the car more energy of motion: the low ramp or the middle ramp? Write the word.

   middle
6. 5.

   A faster car hits the foam block. Will the block be pushed farther or not as far? Write farther or not as far.

   farther
7. 6.

   When the car hits the block, some of its energy of motion moves to the block. Write the word.

8. 7.

   Which result shows the most energy of motion passed to the block? Write the number.

   28
9. 8.

   The faster an object moves, the more energy of motion it has. Write more or less.
