Machines with moving parts will have some amount of friction that makes them less efficient, wears them out, and can make them overheat. In a pump, a piston moves up and down inside a cylinder. If it rubs against the wall of the cylinder, that wastes energy. It should move with minimal friction.
What else can I help you with?
Is friction a problem?
no of Corse not
Does friction force things away?
not necessarily sometimes it creates force sometimes not
Where friction is helpful?
Friction is helpful between car tyres and roads for grip. It is also sometimes used for heating as friction generates heat.
Why is friction a problem for machines?
it can create lots of heat
When might friction be a problem?
when it causes to much heat
What problem did the wheel and axle solve?
To reduce friction
Why friction is problem?
Friction can be a problem as it slows down the movements of objects. It may also stop the movement of object and as such, a bigger force is needed to make the object move faster.
Why do objects sometimes appear to slow down on their own?
Friction.
How does gravity and friction affect sports?
This is because it slows you down and it means that you will get hot feet
Examples where friction is a problem on the earth?
Friction is a problem when walking on icy surfaces, as it can cause slips and falls. Friction can also be an issue when trying to push or pull heavy objects, as the force needed to overcome friction can be significant. Brakes in vehicles rely on friction to slow down or stop, so issues with friction can lead to decreased braking performance.
Is it normal to hate one of your step children?
no you crazy lady how could u say that love your husband, love his kids
Large trucks sometimes have curved shields over their cabs to reduce?
Friction. A+
