# Energy and Speed

Introduction

Let's imagine you're on the ball field ready to send the fastest pitch you can to the batter. What effects the speed of the ball, as it flies through the air towards the batter?

Today you are going to discover how energy and speed go hand-in-hand. We are going to watch a video that will review what energy is, and how it effects the speed and distance of a traveling object.

We will watch the video together, then you will get with your shoulder partner. Together you two will complete the note catcher that you are given.

With your partner, you are going to test out how the distance and speed relate and effect one another.

Process

If you look around the classroom, you'll find materials at stations. Table 1 will go to 1, table 2 will go to 2, etcetera. At this station you will find a long, clear plastic tube with marbles, a timer, and a measuring tape. While one partner holds up the tube, another will drop the marble into the tube, and another will time how many seconds it takes from the marble being dropped to where it stops. Then another will use the tape measure to record how far the distance of the marble travels. All students will have a graphic organizer to record what you're seeing. Take note of how high the tube is held, how far the marble travels, and the time it takes for the marbles to travel at different heights/distances.

Evaluation

Now you will independently answer the following closure questions on your own sheet of lined paper:

1. What is the formula to find speed?

A.  distance/time

B. time/distance

C. speed x time

D. distance x time

2. When dropping the marble, what happened when the marble was dropped at a shorter height?

3. When dropping the marble, what happened to it when the height of the tube was risen?

4. How does height effect the distance of the marble traveled?

5. Speed is defined as how ________ an object is _________.

6. When playing the skate park game, what did you notice happened to the boy on the skate board when placed at the top of the ramp at a medium speed?

7. When playing the skate park game, what difference would you see in the distance traveled when started at the middle of the ramp versus at the top of the ramp?

8. If an object is traveling at high speed with a short distance, how is the time effected?

9. True or false: If an object is traveling at 30 mph in a long distance, it will take it longer time to travel versus traveling the same distance at 60 mph.

10. What is the rate at which an object covers a distance?
