Potential energy is not affected by speed.
fRiCtIoN!!
Car brakes work by applying friction between two surfaces converting the motion (kinetic energy) to heat and slowing down the car. Traveling a downgrade for long distances can result in the brakes overheating and the friction surfaces grinding down and/or burning out. The correct thing to do is to downshift your transmission to prevent the vehicle from gaining too much downhill speed.
Gas molecules change their motion when they bounce into the surfaces of their containers. If the surfaces absorb the impact, then energy is transfered out of the system and particle speed decreases.
i think it is kinetic energy to thermal energy.
No. The speed of the object does not affect the amount of friction between an object and the surface. Friction is affected by the types of surfaces in contact, smoother surfaces produce less friction, and the weight of the object moving horizontally affects the resistance relative to the two surfaces in contact. Greater weight causes greater resistance.
Its charge is always 1.6X10-19 However when it's speed increases, it has more energy
the brakes affect the speed
If she's coasted down the hill at some speed, then she'll be carrying kinetic energy at the bottom of the hill.
The speed; the acceleration; the time it takes to react before the driver notices a danger (and applies the brakes). The acceleration is affected by the mass of the car; by the quality of the brakes; and by the condition of the road (for example, whether it's slippery).
Answer this question...Flt control surfaces, (IE) Ailirons, Elevators, rudders, Flaps, Speed brakes.
Using brakes slows your speed.
