False. Energy is converted to another form. However, it is converted to UNUSABLE energy.
Friction does not "destroy" energy, but rather it transforms some of the mechanical energy into heat energy due to the resistance between two surfaces in contact. This transformation of energy can lead to a loss of usable energy in a system.
it doesnt
its doesnt help... it only destroys... much like humans.
friction forces
-Cody Simpson does not have a girl freind period! he said it on facebook and twiter! - actuaaly no he doesnt have a girlfriend he is currently single he even said it on twitter. He is single and does not have a girlfriend.
...friction. This is not best explained chemically, but with Newtonian physics.
Friction is essential for Walking and other movement. So obviously it is of paramount importance in football. Without friction, A player can't grip the ball, the ground pr other players. Running, which is the base of football, doesnt exist without friction. Hence, no friction = no football.

if your talking about salt, it only adds friction and therefore grip for vehicles, it doesnt stop them freezing
Friction doesnt not depend on the surface area...but the force of friction does! We cannot change the friction of a material but we can change the force due to that friction on another material in contact with it. Using this concept, racing cars have bigger tires to minimise the force of friction acting on them. They cannot change the friction of the road, so they change the resultant force on the tires.
No, it is not true. Friction can still occur even if the object does not move. The force applied may overcome static friction but not cause the object to move due to other factors like weight or surface roughness.
Friction is the force most likely opposing your efforts when you push on a stationary object and it doesn't move. Friction exists between surfaces in contact and resists the motion of objects.
