Give examples of why you need friction?
Walking to move forward, same for anything that moves. If there was no friction it would be like walking on oil.
How much torque that car wheel need?
Sufficient to overcome the inertia and friction of the vehicle.
What are ways to over come friction?
The best way to overcome friction is with lubrication. With friction loss due to aero-dynamics or hydraulics you need to reduce drag.retold by Matt Isagan)
How can friction be both a positive and negative aspect in your every day lives?
a positive aspect is that friction stops your car from sliding so you stay on the road a negative aspect is that when it comes to machinery engineers need to calculate in friction. the friction that comes with making products will make companys actually lose money. you need more energy to overcome friction. this is why we haveto eat all ofthe food we do. to overcome all the forces of friction acting on us we need to fuel our bodys.
Why do lorries need a force to keep them moving at a steady speed?
They need the force to overcome the friction between the lorry and the road.
Does increasing friction make it easier to move an object?
no. No because we would need to overcome friction when moving, causing us to move slower.
What type of friction is involved in walking?
Grip is a type of friction that people need in order to walk comfortably. Without grip, people would slide and have nasty falls.
What useful friction?
You need friction to slow down or turn while skiing and ice skating. Auto braking during driving. Walking or the movement of the motor vehicle depends on friction or there will not be movement.
How can you overcome the disadvantages of coal?
You can't overcome them! The main disadvantage of coal is that it is a non-renewable fossil fuel. Therefore it will run out in the future. We need to find viable alternative energy sources.
What do you need in order to have a Force greater than zero acting on an object?
Push it, or pull it. You may have to push hard enough to overcome a force of friction.
Why do you need friction?
we need friction because if there were no friction the objects around us will slide
What are the advantages and disadvantages of having friction in sport?
These are a few of the great many advantages and disadvantages of having friction in sport: Friction allows a running person to stop, change direction, jump, catch a ball, and throw a ball. Friction between a ball and the air limits how far it can be thrown (although gravity has an even greater effect). Runners require energy to overcome the friction between their feet and the ground.
