## What are two ways that friction is harmful when riding a bike?

1) the sole of shoes can be destroyed. 2) it causes the damage to machines. It is helpful while riding the cycle: friction helps us to stop our cycle when we need.

In what ways can friction be harmful?

Friction reduces the speed of the moving objects and it even stops the motion of the object. Friction between the objects produces heat. This results in the wastage of energy in the machines.

### How is friction caused in cycling?

Direct friction occurs when wind comes into contact with the outer surface of the rider and the bicycle. Racing cyclists often wear “skinsuits” in order to reduce direct friction. Direction friction is less of a factor than air pressure drag.

Is there friction when you ride a bike?

Friction is a force that resists sliding motion between contacting surfaces. A bike, for example, has many instances of friction. The brake pads and the wheel rims have friction when we brake. There is friction between the handlebar and the hands that allows for a successful gripping.

#### What are two ways in which friction can be useful?

Friction can be a useful force because it prevents our shoes slipping on the pavement when we walk and stops car tyres skidding on the road. When you walk, friction is caused between the tread on shoes and the ground. This friction acts to grip the ground and prevent sliding. Sometimes we want to reduce friction.

Why do heavier objects have more friction?

A: Heavier objects press together with greater force, and this causes greater friction between them.

## What is created when friction does work?

Friction can generate static electricity. The harder two surfaces are pressed together, the more force it takes to overcome the friction and get them to slide.

Why do cyclists wear tight clothes?

They wear tight clothing, they ride downhill in a tucked position, and they ride very closely together. Loose clothes create a large amount of aerodynamic drag and slow you down. The more form fitting the clothes are, the more aerodynamic you’ll be, and the faster you’ll go.

### What force do you use when you ride a bike?

The primary external forces on the bike are gravity, ground, friction, rolling resistance, and air resistance.
