You can minimize friction in your car (notably in the engine) by always using the lubricating oil and oil level that is recommended by the car manufacturer. Keeping grease points in good condition also helps to reduce friction and wear and tear on moving parts.

How are you able to minimize or maximize friction?
You can minimise friction by Decreasing surface area, making area smoother, lubricating it(eg. car parts) and the opposite to maximise friction.
When do participants in swmming maximize friction when do they minimize it?
you maximumize friction to train and when you compete you minimize it
List and Explain 2 reasons why you might increase friction between two objects?
Car tires and the road: increasing friction will allow a car to brake faster. Shoes and the ground: increasing friction will make it less likely for you to slip.
What are the forces acting on the cars and explain why the cars do not slide down the hill?
The car is being acted upon by gravity and friction. The reason that the car doesn't slide down the hill is because friction is keeping the car in place.
A car's motor does 2500 kJ of work in moving the car however the car only has 18 kJ of kinetic energy. Explain how this can happen?
The remaining energy got lost to friction.
What is a feature of a car that increases friction?
the front boot of the car increases the friction on the car
What are some situations where friction is good and some some where friction is bad?
In situations where you want to create heat or dissipate kinetic energy, friction is usually a good thing. Friction when rubbing your hands together creates heat, which you appreciate, and friction between your brake pad and brake disc slows down your car, which is also a good thing. In situations where you want to maintain kinetic energy or minimize heat, friction is usually bad. Air friction slows down a glider, limiting its range, and mechanical friction in a car rolling on a flat surface causes it to stop without the brakes being applied.
Which force is responsible for wear and tear of machinery?
Friction is the main force that is responsible for the wear and tear of machinery, this is why mechanicalæparts are sometimesæoiled, to minimize the friction.
Do car brakes reduce friction?
Friction is what makes the brakes stop the car.
How does friction change how far a car goes?
Friction does work to slow down the car. Thus, the more friction there is, the less distance a car can go.
Explain the term dynamic limiting friction and rolling friction?
awesome looking
What game requires little or no friction?
Curling. A kettle is slid across the ice. Team members brush the ice in front of the kettle to minimize friction.
