What is The primary factor in decreasing the Kinetic Energy of an object?
Important factors in decreasing Kinetic Energy are Gravity and 'drag' from Friction.
What are uses of decreasing or increasing friction in daily life?
applying a brake
What is the effect of decreasing the block in contact with the table on kinetic friction?
Decreasing the block in contact with the table reduces the normal force acting on the block, which in turn decreases the frictional force. This results in a lower kinetic friction force between the block and the table.
What is the primary factor in decreaseing the kinetic energy of an object?
Decreasing the mass or Decreasing the velocity
3 ways of decreasing friction?

Activities that require increasing and decreasing friction?
Activities that require increasing friction can include using sandpaper to roughen a surface or tightening the grip of shoes with a shoelace. Activities that involve decreasing friction can include applying lubricant to machine parts or gliding on ice skates with a thin layer of water on the ice.
Can friction be important?
Yes, friction can be important in various situations. It is essential for allowing us to walk, drive vehicles, and hold objects. Additionally, friction is crucial for preventing slipping and ensuring stability in many everyday activities.
How can friction increased?
Friction increases or decreases based on the surface changes. If a box were sliding down a smooth hill that suddenly becomes quite rough, then friction would increase. It would be the same vice versa for decreasing friction.
How can friction be increased?
There are different ways through which helpful friction be increased. The easiest way is using coarser or rougher surface to increase resistance.
