Question

Write an activity to show that rolling reduces friction?​

Answer 1

Answer:

In order to move a heavy object along the ground, rollers can be used to reduce the resistance from friction. A roller is a long object with a round cross-section. It must be long enough not to fall over and can easily roll along the ground or some even surface. A log or even a pencil can be used as a roller.

Some examples of items that have rolling friction are:

Truck tires.

Ball bearings.

Bike wheels.

Soccer ball, basketball, or baseball.

Car tires.

Skateboard tires.

Railroad steel wheels.

Bowling ball.
