A force is needed to start something moving and to stop it once it is moving. A force can make something speed up or slow down. Friction is a force generated when surfaces move across each other.
no, movement creates friction
Friction. The brake pads clamping on the rotor creates friction which creates heat.
Yes, anything from 2 surfaces creates friction.
usually when you rub on to something it creates heat so that makes friction. Ice has no friction because it slips
Water flowing through the pipe creates some friction. That friction creates vibration, vibration = sound.
Rubbing causes friction, friction creates heat.
Moving a blade through a dense material like wood creates friction . Friction creates heat.
Moving a blade through a dense material like wood creates friction . Friction creates heat.
Moving a blade through a dense material like wood creates friction . Friction creates heat.
When two objects rub against each other, it creates friction. Friction is the force that opposes the motion of one object relative to another when they are in contact.
This is called friction. Moving an object in a very tight space generates heat.
Relating to cars, the friction of the tires creates a backward force on the pavement, the pavement then creates an opposite forward force that pushes the car forward on the road.
