-- If the car is a hybrid or all-electric, then braking converts some of its kinetic energy
into some heat, which is dissipated into the air, and some electrical energy, which is
put back into the batteries.
-- If the car is the classic internal combustion type, then braking converts some of
its kinetic energy to all heat, which is dissipated into the air, and which can burn up
the brakes if it goes on for too long.

How much energy does it take to stop a 3000 lb car traveling at 30 miles per hour?
Trick question--The answer is none. Indeed, energy in the form of heat is produced by the car stopping. But no energy is required to stop it. The brake pads, and drums or discs absorb energy and get hot.
A car traveling at 60 mph carries times the energy as the same car traveling 30 mph?
12
What has greater kinetic energy a car traveling at 35 miles per hour or a car traveling at 50 miles per hour?
Kinetic Energy is defined as the energy associated with motion. This is in contrast to potential energy which is associated with an entity's energy at rest, and it's potential for motion. Kinetic Energy can be calculated using this formula: KE = 0.5*Mass*Velocity^2, where KE = Kinetic Energy It is apparent by the formula that the same car traveling at a higher speed will have a greater kinetic energy than it does when traveling at a lower speed. Therefore, when the car travels at 50 mi/hr it has a higher kinetic energy than when it travels at 35 mi/hr. Let me just note that if we were talking about two different cars then we'd have to consider the weights of the cars.
Which has a greater kinetic energy a car traveling at 30 km h or a car half that mass traveling at 60 km h?
60. K= 1/2mv^2 therefore when v is larger, there is more kinetic energy
How many kilocalories of heat are generated when the brakes are used to bring a 960 kg car to rest from a speed of 101 km per hour?
((.5 * 960) * ((101 * 1 000 * 60 * 60)^2)) * 0.000239005736 = 1.5166917 × 1016 1/2 M V^2= kinetic energy times conversion from joules to kilocalories.
What happens when you step on the breakes?
Thee Car Stopsss -_-
What energy conversion occur when solar powered car is moving?
Chemical energy and heat energy
What is the energy conversion in car engine?
Chemical (gas) to thermal (combustion) to mechanical More Simply: Chemical Energy to Mechanical Energy
Is it a hit and run if a car throws rock and breakes my car window and leaves the scene?
No. The driver of the car that threw the rock has no way of knowing that his car caused the accident.
A man filling his car with gas is expecting what kind of energy conversion to happen?
Chemical Potential Energy to kinetic energu
How do you remove a stuck key in the ignition of 2002 Mitsubishi eclipse?
Try to put your car on the parking breakes.
What are 5 physical changes that can occur to a substance?
What type of energy conversion is using gasoline in a car
What kind of energy is created when an energy conversion is happening?
Energy conversion takes place when one form of energy is converted to another form. An example would a turbine, which converts heat energy to mechanical energy, or a generator which converts mechanical energy to electrical energy, or an electric motor which converts electrical energy to mechanical energy. In all conversion processes energy is lost (i.e. it is converted to heat at a low temperature). The useful power output of a machine is always less than the power input, by a ratio called the efficiency, usually expressed as a percentage. Typical efficiency for an electric motor is 95%, for a car engine 25%.
What form of energy is generated when gasoline is burned in a car engine and the car moves?
kinetic energy is created
A car that brakes suddenly comes to a screeching halt Is the sound energy produced in this conversion a useful form of energy?
because it have sound energy
How does potential energy become kinetic energy during your ride?
The answer depends on the ride. If you go for a ride in you car on a level road, there is no conversion of PE to KE.
Share information about when kinetic and potential energy will be critical for the pinewood derby?
I would assume that the most critical point would be at the moment of inertia, which would take place in the curve of the track as the car transitions from the hill to the flat of the track. This is when the potential energy would be converted to kinetic energy, thus propelling the car towards the finish line. If the weight in the car is not concentrated, the car will use more potential energy to overcome the point of inertia resulting in less potential energy available for the conversion to kinetic energy. Also if the center of mass is to far back on the car at this point, the front wheels on the car will lift, causing the car to again lose valuable potential energy and limiting the amount available for the conversion to kinetic energy.
