Forces

Today we're going to be summarising what we've done so far on forces.  Open a word document and complete the following.
1. If you have a zero resultant force, what information do you still NOT know?
2. Complete the activity here, then give your answer to the question with working out shown.
3. Copy the diagram here into your document. What two things do the arrows represent?
4. For the link above, continue through the last two pages of information and then try the test bite. What are two things that can influence stopping distance?
5. Find a photo online of anything (appropriate) that involves different forces - maybe different sports, objects, athletes, chemistry. Label this photo with force arrows, thinking about size and direction of forces involved. List the forces you have arrowed below the photo.
6. Copy the picture below into your document. What is the resultant force here? Why? What things could happen to make the resultant force not zero?                                                      
7. HOMEWORK - You need to find a definition of terminal velocity to bring to class next week. If you can, include information about how it occurs and what forces are involved.
