What are some situations where friction is good and some some where friction is bad?
In situations where you want to create heat or dissipate kinetic energy, friction is usually a good thing. Friction when rubbing your hands together creates heat, which you appreciate, and friction between your brake pad and brake disc slows down your car, which is also a good thing. In situations where you want to maintain kinetic energy or minimize heat, friction is usually bad. Air friction slows down a glider, limiting its range, and mechanical friction in a car rolling on a flat surface causes it to stop without the brakes being applied.
A pendulum set in motion eventually stops because?
1). Air resistance 2). Friction in the pivot. These two effects rob energy from the pendulum. Without air resistance or friction in the pivot, a pendulum, once set in motion, would not stop.

Please state whether or not friction is involved.
Without friction there would be?
NO friction
Can you not walk without friction?
You require friction in order to walk.
What would be like to climb a rope without friction?
Without friction - climbing a rope would be impossible !
What is examples of friction?
The fact that you can walk without sliding is an example of friction.
What is express cargo?
Cargo or freight that is shipped without stops.
Where is friction in cycling?
the friction is between the tyres of cycle and the road surface. Without friction movement is impossible.
Can you shot an A5 12 ga without friction rings?
The weapon was not designed to be fired without the friction rings. You risk damaging it if you fire it without them.
Why is friction important in baseball?
friction is importent cause without it you can play baseball
What happens if there were no friction?
Without friction, objects would have no resistance, therefor loose no energy as a result. For example, without friction a ball could roll up and down a half-pipe continusily without loosing hight.
