Friction Lab
1) What is friction?
The resistance caused by one object moving over another object.
2) What causes friction?
An object moving over another
3) Record your data in the table below as you conduct the activity

4) When you moved the black across the table, was the force of friction acting against the block greater or less than the force you exerted on the block? How do you know?
less because it caused the object to accelerate or change direction
5) Described the motion of the block when balanced forces acted on it and that of the block when unbalanced forces acted on it.
Balanced-Does not move
Unbalanced- Moves places
6)Was there a difference in the force required to pull the block across the path without sandpaper and that to pull the block across the path with sandpaper? How could you use what you learned from this demonstration to describe the force to drag a desk across a tile floor and that to drag a desk across a carpeted floor?
Yes because the sandpaper applied more friction, therefore the box was not as easy to pull. If the desk is pulled across the tile floor, the surface is smoother, compared to pulling it across a carpeted floor, which would be harder since there is more friction being appllied.
7) How could you decrease the amount of friction on a dirt road?
The dirt road would have to be smooth in order for there to be less friction, so you could always pave it.
