Why do f1 cars need friction?
F1 cars need friction to maintain grip on the track and maximize traction, allowing for better acceleration, cornering, and braking performance. Friction is essential for the tires to generate the necessary grip to navigate the high-speed corners and stop effectively during racing conditions.
When or where might you need as little friction as possible?
You might need as little friction as possible in situations like lubricating machine parts to reduce wear and improve efficiency, minimizing friction between moving components in high-speed vehicles like airplanes or cars to maximize speed, or reducing friction between surfaces in medical devices to prevent tissue damage during surgery.
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
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.
What forces would be at work if you were trying to move a huge block of stone?
If you were trying to move a huge block of stone, the forces of friction would be applied against you. To get the stone in motion, you must overcome static friction, the friction force that acts on objects that are not moving and is always working in the direction opposite of your applied force. Then, to keep it in motion, you must overcome sliding friction, which, though it takes effort to keep moving a stone, is substantially less than the effort to get a stone into motion originally.
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 does a car need a forwards force to keep moving?
Resistance from air and friction.
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.

Once the crate is sliding how hard do you push to keep is moving at constant valocity?
You should push with a force equal to the force of friction acting on the crate. This will counteract the friction force and allow the crate to continue moving at a constant velocity. Pushing with a greater force will accelerate the crate, while pushing with a force lower than the frictional force will cause it to decelerate.
Do cars need friction to stop?
Yes, cars need friction between the tires and the road to stop. When the brakes are applied, the brake pads create friction against the brake rotors, which slows down the wheels and ultimately brings the car to a stop. Without friction, the tires would not be able to grip the road surface and the car would not be able to stop effectively.
How do fast cars acieve the speeds against firction?
High Horse Power Low weight Low friction And at higher speeds you will need aerodynamic considerations. Like a wing to keep it on the ground and controllable.
Is it true cars need friction to stop?
Yes, friction is essential for cars to stop. Braking systems rely on the friction between the brake pads and the brake discs (or drums) to convert kinetic energy into heat and ultimately stop the car. Without friction, the wheels would not be able to slow down or stop effectively.
