What else can I help you with?
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 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
What is an example of an event when momentum is not conserved?
An example of an event when momentum is not conserved is when two ice skaters on frictionless ice push off each other. When they push off, one gains momentum in the opposite direction, causing the total momentum of the system to change from the initial state. This violates the principle of conservation of momentum.
How do you escape from a frictionless room?
If you are in a frictionless room, you can't push off of anything to exert enough force to move away. However, if you have a bottle of compressed gas or liquid, the force of the escaping gas from the container will exert a reaction force to push you where you need to go. If you are near a wall, you can push off of that.
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 ice frictionless?
NO. There are several fun experiments to help you understand this... Do a search on... "friction experiments for kids."
What is an example for conservation of momentum?
An example of conservation of momentum is when two ice skaters push off each other on a frictionless surface. As they push off in opposite directions, the total momentum of the system remains constant before and after the interaction, even though their individual momenta change.
What is 'off ice' in hockey?
happening when players are off ice
What are property that affects how much light will be reflected off it?
The extent of smoothness tells us that how much light will be reflected off any substance.If the surface is frictionless the light reflected will be cent percent.
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
