Aim
To measure the force of limiting friction for rolling of a roller on a horizontal plane.
Apparatus
Same as in Experiment 9 and lead shots as rollers.
Theory
Rolling friction. It is the friction acting on a body in rolling motion.
Force of rolling friction. It is the least force required to make a body start rolling over a surface.
Diagram
Procedure
1. Same as in Experiment 9. Spread lead shots over the table top to form a single layer.
2. Weigh the wooden block and put it over the layer of lead shots. Steps from 3 to 12 are same as in Experiment 9.
Observations
Same as in Experiment 9.
Calculations
Same as in Experiment 9.
Result
Same as in Experiment 9.
Precautions
Same as in Experiment 9.
Sources of error
Same as in Experiment 9.
