What else can I help you with?
How could a person who is a rest on completely frictionless ice covering a pond reach shore?
Even on 'frictional' ice it is possible to crawl, slide, walk on the ice.
Is conservation of mechanical energy likely to hold if a hockey puck slid on a frictionless surface of ice?
yes
How can a fully dressed person at rest in the middle of a pond on perfectly frictionless ice get to shore?
Take off some clothing to walk on and avoid slipping.
How does spikes help climb on hard ice?
The spikes dig into ice and allow the climber to involve his feet on the slippery ice. Hard ice may require more force to 'dig' into, but spikes help prevent snow buildup, and provide stability and traction on an otherwise frictionless surface.
Is there any frictionless train?
No there is always a resistive force such as air resistance. The closest frictionless train is the japanese magnetic train which has no friction on the track.
What is the oppositon of friction?
slickness, smoothness, frictionless
Can acceleration happen on a frictionless surface?
yes
Where does friction happen?
Everywhere! Frictionless surfaces do not exist.
What is frictionless compressor?
it is the act of without friction.
How can you get away in a frictionless surface?
You have to get rid of mass. Throw things, spit, fire a gun if you have one, etc. Since momentum is conserved, every time you get rid of something, you move across the ice in the opposite direction.
What requires less effort sliding a 1 kg box on an ordinary floor or sliding a 2000 kg box on a frictionless floor?
2000 kg box on a frictionless floor
When will frictionless engine be 100 percent efficient?
at 0'kelvin
