You would not be able to walk. Walking is the friction of your shoe againjst the ground. Without friction, you would not go anywhere. A good example, all though not completely frictionless, is ice. Walking on clean, clear ice is very hard because of the lack of friction.
The force called supportive force is a force exerted by hard surfaces
the force we think is called gravity No its friction.
In my opinion , frictional force will increase
Frictional force exist between two moving objects that make it hard for them to move.Frictional force causes objects to slow down if force is not applied continuously to the moving objects. Frictional force causes some of the energy to be converted into the wasteful form of energy.
A skateboard should be used by pushing hard on the ground.
no
It depends how hard you fall.Most times skateboard accidents are fractures.
soft ones make it easyer to turn
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.
that is a very hard question to answer sorry i do not no
Yes, and if you have a skateboard be careful not to use any tricks that you've wanted, and like those other people died on a skateboard, and it's really hard and dangerous to use a trick in a skateboard. Please do not use a skateboard trick.
The original type of skateboard is much better than the other! It is very hard to do tricks on longboards and on plastic cruisers
well not realllyl just keep trying and have lots of passion for it.
Yes
soft ones
