Let’s see how much you’ve picked up with these experiments and the reading – answer as best as you can. (No peeking at the answers until you’re done!) Just relax and see what jumps to mind when you read the question. You can also print these out and jot down your answers in your science notebook.

1. What is velocity?


2. What’s the difference between speed and velocity?


3. What is terminal velocity?


4. Why do feathers have a low terminal velocity?


5. Why do bowling balls have a high terminal velocity?


6. Gravity pulls equally on a man with a closed parachute and the same man with an open parachute. Why does the man fall more slowly with an open parachute?

7. Newton’s first law says “An object at rest stays _______?”


8. And it says “an object in motion stays ________?


9. What is inertia?


10. What does inertia have to do with the last time you spilled a drink in the car?


11. Which has more inertia: a taco, or a tow truck?


12. I drop a feather and it takes the feather 4 seconds to fall 8 feet. What is the velocity of that feather? (Velocity is v=d/t)


13. So how long would it take that same feather to drop 12 feet? (t=d/v)


14. Which drops with more acceleration; a bowling ball or a golf ball?

    Thanks! I didn’t see it before.

  2. Yes, they are included in the Lesson Plan download in addition to being on the answer page itself as a clickable link.

    Wondering if there is a printer-friendly button for the exercises page? That would be really helpful.
