Question

write an activity to show wheel reduce friction

Answer 1

roller is a friction-reducing machine that allows you to move a heavy object along the ground. Rolling friction is much less than sliding friction.

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.

hope it helps!!❤❤❤..
