Answer 1

Answer:

Friction is a force between two surfaces that are sliding, or trying to slide, across each other. For example, when you try to push a book along the floor, friction makes this difficult. Friction always works in the direction opposite to the direction in which the object is moving, or trying to move.

Answer 2

FRICTION

• It is a force which oppose the motion or oppose the intension of motion.
• Friction is occurs at the point of contact.
• Friction is occur between the two surfaces.

TYPE OF FRICTION

STATIC FRICTION

• When two objects having more relative motion between two bodies in contact is called Static friction.
• Static friction help us to start the motion or move.
• For walking on ground or for starting a motion Static friction is necessary.

LIMITING FRICTION

• To start a object motion minimum limiting friction must be applied.
• Direction of limiting friction is always opposite to the direction in which body have to move.

KINETIC FRICTION

• Realtive motion between bodies which is in contact
• It help us to stop the motion.
• it is always slightly less than the limiting friction.
• It is also known as dynamic friction.
