Question

What is the relationship between friction and velocity?

Answer 1

$\huge \sf \underline{ \purple{Åñwêr :}}$

• Friction is typically unrelated to speed. When the surfaces start to melt or otherwise change because of heat build up or inability to follow the surface then things will change.

• Friction is related to velocity in that it acts to reduce velocity. In other words it causes moving objects to decelerate.

• The friction force may also act as one of the forces in a moment that is causing motion. If the motion is rotary, or following any path, then the friction force may be simply a part of the system of forces that influences motion.

Hope It's Helps! :)

Answer 2

Friction is exerted when an object sliding over a surface and its formula
Ff =miu times normal force miu is the coefficient of friction
Velocity is how fast a body moves with in direction and velocity =displacement over time
