1. how does the friction affect forward
motion? give an example.
2. describe two ways to change the
frictional force between two solids surfaces.
change the lubrication between the two surfaces
change the normal force between the two surfaces
3. how does air resistance affect the
velocity of a falling object?
4. what two sources of friction do you
have to overcome when you are walking?
5. if you push a chair across the floor
at a constant velocity, how does the force of friction compare with the force
exert? explain.
6. if you push a book against a wall
hard enough, it will not slide down even though gravity is pulling it. use what
you know about newton’s laws of motion to explain why the book doesn’t fall.
