How does kinetic friction affect the motion of a block in a block-and-pulley system?
Kinetic friction in a block-and-pulley system opposes the motion of the block, causing it to slow down and potentially come to a stop. This frictional force acts in the direction opposite to the motion of the block, reducing its speed and affecting its overall motion within the system.

How is static friction and kinetic friction differ from each other?
Static friction occurs when an object is at rest on a surface, preventing it from moving. Kinetic friction occurs when an object is already in motion on a surface, resisting its motion. Static friction is usually stronger than kinetic friction.
How does friction affect an oject's motion?
Friction is a force that opposes motion between surfaces in contact. It can slow down an object's motion by converting kinetic energy into heat. The amount of friction depends on the nature of the surfaces and the force pressing them together.
Which form of friction is harder to overcome static or kinetic?
Static friction is generally harder to overcome compared to kinetic friction. This is because static friction opposes the initial motion of an object and requires more force to initiate movement, while kinetic friction opposes the motion of an object already in motion.
How do static friction and kinetic differ from each other?
Static friction is a force that must be overcome to start motion. Kinetic friction is the force that must be overcomne during motion or the motion stops.
The direction of kinetic friction is always?
The direction of kinetic friction is always opposite to the direction of motion of the object.
