## What type of motion does a bicycle have?

As the wheels rotate on their axis they perform a rotational motion. Due to this rotation with the contact of the ground the bicycle covers a certain longitudinal distance. So the wheels also perform a translational motion concerning the ground.

## What part of bike reduces friction?

Friction is reduced (wheels, handle bars) with ball bearings and grease (rolling and lubricants). Look at ball bearings taken apart to see how they work. Look at pictures of other places that have ball bearings (handle bars, wheels, pedals).

## What are the 4 types of motions?

The four types of motion are:

• linear.
• rotary.
• reciprocating.
• oscillating.

## What is periodic motion with example?

Periodic motion, in physics, motion repeated in equal intervals of time. Periodic motion is performed, for example, by a rocking chair, a bouncing ball, a vibrating tuning fork, a swing in motion, the Earth in its orbit around the Sun, and a water wave.

## Why do cyclists crouch down?

Racing cyclists crouch down low on their bikes to reduce the air resistance on them. This helps them to cycle faster. They also wear streamlined helmets. … Their smooth shapes make the air resistance smaller, which allows them to travel further on the same amount of fuel.

## What are some examples of static friction?

Static Friction Examples

• Papers on a tabletop.
• A towel hanging on a rack.
• A bookmark in a book.
• A car parked on a hill.

## What are 2 common examples of fluid friction?

Fluid Friction

• Air pushing against your hand when you stick it out the window of a car (external)
• Water pushing against a swimmer’s body as they move through it (external)
• The movement of your coffee as you stir it with a spoon (external)
• Sucking water through a straw (internal)
• Submarine moving through water (external)

## Why does friction cause circular motion?

Now before sliding starts, to oppose the outward relative motion, static friction comes to play. It opposes the motion by acting in opposite direction i.e., radially inward to the turn. Thus if you imagine the turn as a part of a circle, the static friction will play the role of centripetal force.
