Grade 9 Science Experiment 4 - How does Friction Affect the Motion of Objects?
The purpose of this science fair project is to explore the physics of friction. Friction is the force between two surfaces when they are rubbed together. The science fair project will demonstrate the effects of friction in many instances including smooth and rough surfaces.
Following are properties of Friction:
- Two smooth surfaces rubbed together causes little friction.
- Two rough surfaces rubbed together causes great friction.
- Less friction occurs when a liquid is between the two surfaces.
- More friction occurs when two surfaces are forced against each other.
A common example of the effects of friction deal with the icy, snowy roads in the winter. Icy, snowy roads can be very slippery because the liquid water doesn't cause much friction with a car tire. Therefore, sand and salt are sprinkled on the roads. The sand is a rougher substances that will cause more friction with car tires thus helping cars to avoid sliding off the road.
Rubbing smooth surfaces together will yield less friction than rubbing rough surfaces together.
