Fighting Friction

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it comes into contact with another surface.

Front

What type of energy is created when rubbing two objects together?

Back

Heat energy is created when rubbing two objects together due to friction.

Front

What happens to the temperature of an object when friction is applied?

Back

The temperature of the object increases because friction generates heat.

Front

How do rubber soles on shoes help prevent slipping?

Back

Rubber soles increase friction between the shoe and the ground, providing better grip.

Front

What is an example of friction in everyday life?

Back

An example of friction is when car tires grip the road while driving.

Front

Why do hands feel warm when rubbed together?

Back

Hands feel warm when rubbed together because friction generates heat energy.

Front

What is the relationship between friction and heat?

Back

Friction causes heat to be produced when two surfaces rub against each other.

Front

How does friction affect the movement of objects?

Back

Friction slows down or stops the movement of objects by opposing their motion.

Front

What can increase friction between two surfaces?

Back

Rough surfaces and materials with high grip, like rubber, can increase friction.

Front

What is an example of reducing friction?

Back

Using oil or grease on machinery reduces friction between moving parts.
