Answer:
1) Friction is the force that opposes motion between any surfaces that are in contact. There are four types of friction: static, sliding, rolling, and fluid friction. Static, sliding, and rolling friction occur between solid surfaces. ... Fluid friction occurs in fluids, which are liquids or gase
2) Friction is one of the strength that play an important task in our everyday life. The beautiful holding of Friction will contain the blocking of your vehicle before hitting somebody else car on a busy road.
3) like Open the door, push a table, push a car
4) push or pull can change the speed of a moving bicycle. If the force is applied in the direction of motion of the object, its speed increases. If the force is applied in the direction opposite to the direction of motion of an object then its speed decreases
Answer:
- Friction is the force that opposes motion between any surfaces that are in contact.
There are four types of friction:
- static
- sliding
- rolling
- and fluid friction.
2.A friction is very much desirable to stop the body from its moving condition
3.like opening the door, lifting a bag, kicking a ball.
4.A push or pull can change the speed of a moving bicycle. If the force is applied in the direction of motion of the object, itsspeed increases. If the force is applied in the direction opposite to the direction of motion of an object then its speeddecreases.
