Question

1. what are the three types of friction and when does each apply?

Explanation:

• Static friction: It acts when an object is at rest and a force is applied to try to move it. For example, when you push a heavy box that doesn't move immediately, static friction is opposing the applied force.
• Sliding friction: Applies when an object is sliding over a surface. Like a book sliding on a table, sliding friction acts to slow down the sliding motion.
• Rolling friction: Occurs when an object is rolling over a surface. For instance, the wheels of a bicycle rolling on the road experience rolling friction.

Answer:

• Static friction: When an object is at rest and a force is applied to move it.
• Sliding friction: When an object is sliding over a surface.
• Rolling friction: When an object is rolling over a surface.
