When does a car going down the hill have the most kinetic energy?
At the steepest point near the bottom of the hill
How do you find the gravitational potential energy if you have the weight in newtons and the acceleration and the height?
The gravitational potential energy is the product of (mass) x (acceleration due to gravity) x height). The first two terms ... (mass) x (acceleration due to gravity) ... are the object's weight. So if you already know its weight, then the gravitational potential energy is just (weight) x (height) and you don't need to use gravity at all.
When you move your hand or foot your body has converted potential energy into what type of energy?
Isn't the answer kinetic energy or something along the lines of that? I'm an eighth grader with a basic understanding of energy, and that's the first that comes to mind....
Where is the greatest amount of potential and kinetic energy in a roller coaster?
If it is a rollercoaster that has a first drop hill, the roller coaster has the greatest kinetic energy at the bottom of that drop. If it is magnetically launched, the kinetic energy is probably greatest immediately after the launch. However, there are cases where these statements may not be true. (i.e. a drop right after a magnetic launch)The energy is the greatest at the bottom of a drop, before some is translated back into potential energy as the car climbs the next rise.
What part of mechanical energy does the girl is jumping on the trampoline?
If we start with the girl stationary then first she jumps which is the transformation of chemical potential energy to kinetic energy by her leg muscles. As she gains height that kinetic energy (ke) is converted into gravitational potential energy (gpe) which is at a maximum at the top of her jump. As she falls back down again the gpe is converted back into ke. As she lands on the trampoline the ke is stored as potential energy in the springs of the trampoline. As she starts to bounce back up again the springs potential energy is converted into ke and the process repeats.
What is the relationship between Issac Newtons first law of motion and gravitational potential energy?
No Gravitational potential energy equals no force and thus no acceleration.
Where does a roller coaster have the least kinetic energy?
At the tallest point on the track. Potential energy is given by U(Which is potential energy) = mass times height time gravitational constant. You can't change the gravitational constant, or the mass of the roller coaster car. So you have to change the height. PE=mgh so more the height and the mass the more PE

What is the source of potentail energy?
Let's take an example: gravitational potential energy. An object has more potential energy if it is raised to a higher position. The energy comes from whatever raised it up, although it is also possible (as in the case of meteorites) that the object was never on the ground in the first place.Let's take an example: gravitational potential energy.

3 What type of energy is gained as the roller coaster car goes up to the top of the first hill?
It is gravitational potential energy.
Why do roller coasters end lower than where they start?
Since the top of the first hill is the highest point on the track, it's also the point at which the roller coaster's gravitational potential energy is greatest. As the roller coaster passes over the top of the first hill, its total energy is greatest. Most of that total energy is gravitational potential energy but a small amount is kinetic energy, the energy of motion. From that point on, the roller coaster does two things with its energy. First, it begins to transform that energy from one form to another--from gravitational potential energy to kinetic energy and from kinetic energy to gravitational potential energy, back and forth. Second, it begins to transfer some of its energy to its environment, mostly in the form of heat and sound. Each time the roller coaster goes downhill, its gravitational potential energy decreases and its kinetic energy increases. Each time the roller coaster goes uphill, its kinetic energy decreases and its gravitational potential energy increases. But each transfer of energy isn't complete because some of the energy is lost to heat and sound. Because of this lost energy, the roller coaster can't return to its original height after coasting downhill. That's why each successive hill must be lower than the previous hill. Eventually the roller coaster has lost so much of its original total energy that the ride must end. With so little total energy left, the roller coaster can't have much gravitational potential energy and must be much lower than the top of the first hill.

At what point does a roller coaster have the greatest kinetic energy?
Potential energy is at its greatest when the train is at the highest point of the track. At the top of the first hill, before the first plunge. Potential energy = mass * gravity * height mass * gravity remain constant. When Height is greatest, PE is greatest

What two factors influence the gravitational potential energy of an object?
First of all, a clarification on the wording of the question: Gravitational potential energy is the energy associated with the gravitational interaction between objects with mass. Obviously if you just have a single isolated mass, it would not be under the influence of any gravitational fields and therefore there would be no gravitational potential energy. Gravitational potential energy is property that describes a whole system of masses (it could be two masses or three or four or...). When we talk about the gravitational potential energy of an object on Earth, it is implicit that we mean the gravitational potential energy associated with the system of two masses (one being the object in question, and the other being Earth).For simplicity, let's assume that we have two masses labelled m1 and m2. The gravitational potential energy (which I'll label U) is given by the relation:U = (Gm1m2)/r2where r is the distance between the centre of each mass, and G is the universal gravitational constant. You can derive this equation very simply from Newton's Universal Law of Gravitation (which you may be familiar with) and the definition of potential energy. So, what does the potential energy of this system of masses depend upon? Everything that is a variable in the equation! Namely, the mass of each object and their separation. In our everyday example of an object that is some height habove the surface of the Earth, the mass of the Earth doesn't change, and neither does its radius (distance between centre and surface). Therefore, in that particular instance, the potential energy depends only upon two things 1. the height of the object above the surface, and 2. the mass of the object.
What happened to the gravitational potential energy the ball had after i dropped the ball?
Whenever an object falls, its potential energy is first of all converted to kinetic energy.
When in a roller coaster ride does potential energy become kenetic energy?
Potential energy becomes kinetic energy when the car begins its downward descent from the top of one of the rollercoaster's peaks. It accumlates potential energy as it is lifted to the first and highest peak. It regains some of its lost potential energy each time it re-ascends one of the lower peaks, then loses potential and gains kinetic energy as it drops again.
