Effects of friction | You can walk, turn, and push. Moving Parts in a machine work better with less friction between the parts
🗑

Reducing Friction | You use oil in a car to reduce friction and grease on a bikes chain
🗑
|
||||
Lubricant | is any substance that reduces friction and helps moving parts move more friction
🗑
|
||||
Static Friction | A part of friction that makes something straight like a desk so objects can stay on it
🗑
|
||||
Sliding Friction | Like a toy car going on a carpet and the carpet will slow it down
🗑
|
||||
Rolling Friction | Like putting objects on a cart to move it quicker
