1. Imagine a skier sliding down a hill. Draw a simplified "stick figure" type sketch of the situation, and a free-body (force) diagram of
the skier by hand. Assume for now that there is no friction between the skis and the hill.
Use a ruler! Make sure that your axes and force vectors are straight lines and draw your force vectors proportional to their
magnitudes. You can take a picture of your force diagram with your phone and upload it using the image upload tool on the menu
above your answer box.
1. the normal force on an object by a surface is always perpendicular to the surface.
2. the force of gravity is always directly downward.
Hint:
3. use the particle model to represent the skier as a "dot"
4. Label your coordinate axes and the forces
5. Use the parallelogram rule to show the net force acting on the skier. Which way does it point? Is that where it should
point? If not adjust the lengths of the force vectors so that their sum points in the direction of the acceleration!

This is because there is a force exerted by the ground on the crate, parallel to the surface of the ground that opposes motion or attempted motion. This parallel force between surfaces in contact is called the friction force Ff. Make a few predictions: Q13 A wooden crate is sitting at rest on a horizontal table. There is no attempt to move it. Is there a friction force between the block and the table? Q14 Now suppose that you pull on a string attached to the crate, harder and harder, and the crate doesn't move because the friction force opposes your pull. As you pull harder, does Fr increase, decrease, or remain constant? Q15 Now suppose that you pull hard enough that the crate breaks free and moves along the table.
