As an object (I will use a ball for an example) slides across a surface or terrain it will gradually heat up and slow down due to the composition and features on the surface. Such features include coarseness/roughness. Friction is described in Newtons Three Laws of motion.
what is the effect of friction force on plant
If there is more friction with a machine, efficiency is less.
more friction = less speed
Friction will work against force
less friction
what is the effect of friction force on plant
it rubs the steel because its friction!
No
No effect
If there is more friction with a machine, efficiency is less.
more friction = less speed
Friction will work against force
less friction
Friction inhibits the motion of objects.
yes
The work being done will be increased if you pick it up instead of dragging it due to the friction.
No, We cannot do work on friction less surface
