Why do f1 cars need friction?
F1 cars need friction for their brakes, if they didn't have friction on there brakes then it wouldn't be able to brake.
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.
Why doesn't a satellite need fuel to keep moving?
A satellite needs fuel to keep moving because when it's in space there is no air resistance and the gravitational pull and friction won't effect it.
Once the crate is sliding how hard do you push to keep is moving at constant valocity?
You need to push as much as the force of friction is.
Do cars need friction to stop?
Yes, of course.
Why does a car need a forwards force to keep moving?
Resistance from air and friction.
Why do cars need to be lightweight or weigh less?
Heavy cars are not economical. Lightweight cars use less fuel to get them moving and keep them moving.

Why do cars need oil?
cars are made up of mechanical moving components due to continuous moving ,there is friction between parts to reduce friction and longer life of car we need oil fro car Cars need in in order to lubricate the moving parts. In general, motor oil is the most commonly used oil in a car. This oil is meant to lubricate moving parts such as cam shafts, crank shafts, lifters and pistons. Without oil, these metal on metal contacts would heat up and eventually melt due to the friction created. Oil helps by lubricating the surfaces where moving metal parts meet. In addition, oil helps absorb and dissipate the heat generated by the friction.

Do cars need friction to stop?
Yes, of course.
Do you need a force to keep a body moving with uniform velocity?
Not if you ignore air resisteance, friction etc. A spacecraft does not need to fire its engines once in space to keep traveling at the same velocity. However, if your body in question is subject to air resistance or friction, then you need to apply force to keep it moving at constant velocity. For instance on a bike on a flat road, you can freewheel but you slow down due to air resistance and friction (in the wheel bearings and tyres on the ground). You have to pedal (i.e. apply a force ) now and again
Does a satellite need fuel to keep moving?
Satellites do not need fuel to keep moving because of their inertia and the centripetal force.
Why does space probe need very little fuel?
In space there is no friction, so once the space craft gets moving it will stay in motion until it runs into something. The lack or resistance (friction) means it doesn't have to keep pushing to continue moving. It only needs enough fuel to get it up to speed then it will continue on by itself.
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.
