Use the following link to answer the following questions:
http://www.darvill.clara.net/enforcemot/forces.htm
A. Forces: Make sure you have clicked on the forces tab at the right of the screen for the following questions.
1. Forces are measured in Newtons (N). Why are forces considered to be vectors?
2. List three things that can change a force?
3. Explain the force of gravity. (Is it weak or strong? Which direction does act on objects?)
4. What is weight?
5. What is the Earth’s gravitational strength at ground level?
Read and answer the gravity questions on your own.
6. Explain what a balanced force and an unbalanced force.
7. Observe the parachute picture and answer the questions below:
- What forces are acting?
- What can you say about the size of the forces?
8. The resultant force is also called the net force. Explain resultant force.
B. Friction tab: click on the friction tab on the right and answer the questions below
1. What is friction?
2. What are the two main types of friction?
3. What does friction depend upon?
Watch and read the animation about fiction!!
4. What is fluid friction?
5. What does fluid friction depend upon?
6. What is drag?
7. What is a viscous liquid?
8. What is terminal velocity?
Click on the terminal velocity graph to watch what happens to the graph when the sky diver descends
9. List 3 to 5 ways to reduce friction.
10. List 3 to 5 ways to use friction to your advantage.
Read and answer the questions about friction on your own.
Once you have completed all the questions, design/develop a powerpoint presentation on everything you have researched so far with interesting facts you have learnt.
You will present your information to the class.
Best presentation that is creative will be awarded a silver award
