Friction Flashcards
1
Q
What is friction?
A
Friction is a contact force which opposes the motion of an object. It acts in the opposite direction of an object.
2
Q
Ways of reducing friction in everyday objects?
A
Using lubrication - adding oils between surfaces. And rollers - allowing surfaces to roll rather than drag or slide over each other.
3
Q
Ways of increasing friction?
A
Rougher surfaces increases friction (wood rather than tiles), also how hard the forces are being pushed together.
