The car has 1000 kg mass and it was going 20 ms before it stopped at the stop sign what is its potential energy?
Before the driver hit the brakes, the car's kinetic energy was (1/2 m V2) = (500) (20)2 = 200,000 joules.
After it stops at the stop sign, its kinetic energy and potential energy are both zero. The brakes
turned that whole 200,000 joules into heat, and the wind blew it away.
Unless . . .
Unless the car is an electric or a hybrid. What they do is to take that kinetic energy and put
a lot of it back into the battery, so you can use it again, and you don't completely lose it all.
That's what's the big deal about electric and hybrid cars.

When does a skydiver have the gratest potential energy?
A skydiver has the greatest potential energy when they are at their highest point, just before they start to descend. This is because potential energy is dependent on an object's height and the gravitational force acting on it.
How do gravity and potential energy work together to give you a great ride on a roller coaster?
the gravitational potential energy of a roller coaster is equal to two things. Not only is it equal to the gravitational potential energy, it is also equal to the kinetic energy at the lowest point of the coaster. the gravitational potential energy can be calculated as: m*g*h where m is mass (kilograms), g is gravity (9.8 m/s^2), and h is height (metres).d the kinetic energy at the bottom of the coaster can be calculated as (m*v^2)/2 where m is mass (kilograms), v is velocity (metres/second).
What has the least potential energy a ball on top of a slide a ball going down a slide or a ball on top of a 3 story building?
going down a slide
Is potential energy slower than kinetic energy?
Potential energy is unreleased energy - an unmoving rock at the top of a cliff, or a stick of dynamite. Potential energy becomes kinetic energy when it is released - the rock is falling from the cliff, or the stick of dynamite is exploding. So technically the answer is yes. Kinetic even means "motion"! But be careful about saying that potential energy is "slower" than kinetic, or in trying to distinguish between the two based on how fast you perceive an object to move. Kinetic energy doesn't necessarily make an object "look" as if it is moving faster. For example, heating water in a microwave converts potential energy (a difference in voltage between the two prongs of the microwave plug) into kinetic energy (an increase in the temperature of the water), but the water doesn't "look" as if it is going "faster" until it actually boils - the actual change in velocity is at the molecular level of the water.
How does kinetic energy become potential energy?
Here are some examples of how kinetic energy becomes potential energy: -when a rollercoaster car is at the bottom of a hill and going back up the next hill. -when a ball hits the floor and bounces back up. -climbing up a rock wall. Hope this was helpful!
How does potential energy and kinetic energy transfer as a roller coaster moves?
when it is high and stopped its potential when its going down is the kinetic
How kinetic energy and potential energy vary?
Well, the most potential energy is when your going slow or your stopped. The most kinetic energy is like at the bottom of a hill over the first hump in a rollarcoaster, when your going your fastest. Your speed and probably friction will affect it.
What is the potential energy increased by going up hill?
gravitational potential energy
When would a person going down a hill have the most potential energy?
A person going down a hill will have the most potential energy at the top of the hill, where the gravitational potential energy is highest due to the greater height. As the person descends the hill, potential energy is converted into kinetic energy.
When does a skydiver have the gratest potential energy?
A skydiver has the greatest potential energy when they are at their highest point, just before they start to descend. This is because potential energy is dependent on an object's height and the gravitational force acting on it.
What is the potential energy of a 5 kg object sitting on a shelf 3 m high?
The potential energy of the object is given by the formula: potential energy = mass * gravitational acceleration * height. Plugging in the values: potential energy = 5 kg * 9.8 m/s^2 * 3 m = 147 Joules.
What type of energy does a lift gain when going up?
A lift gains potential energy when going up, which is due to its increased height above the ground. This potential energy can then be converted back to kinetic energy as the lift descends.
How does the energy associated with a bicycle change as it speeds up going downhill?
The energy associated with a bicycle changes as it speeds up going downhill due to the fact that potential energy is converted to kinetic energy. The potential energy is the energy of the position. The kinetic energy is the energy of movement.
Which car has the most potential energy going down a hill?
p
What are the conversions between potential and kinetic energy that occurs when you shoot a basketball at a basket?
Seriously -.-' First of all When You throw The Basketball it is going up^ Which is Kinetic energy when is comes down and STOPS it is Potential energy. Oh And this question is in the 6th grade science textbook! The orange textbook....so yeah. BYe
What is a potential energy increased by going uphill?
The potential energy of an object increases when it is raised above a reference point, such as when moving uphill against gravity. This increase in potential energy is a result of the work done to lift the object and overcome gravity. The higher the object is lifted, the greater its potential energy.
What energy transformation is going down a slide?
The energy transformation going down a slide involves potential energy being converted to kinetic energy. As you move from the top of the slide, where you have more potential energy due to your height, to the bottom where you have more kinetic energy due to your moving speed, energy is being transformed from one form to another.
