If you toss a ball in the air at what point does it have the most kinetic energy?
Haitianboi
As soon as the ball has been released.
In this case, the energy starts off purely kinetic; dependent on motion. Once the ball has reached it's highest point, it has converted to potential energy; dependent on height. It then resumes falling back to kinetic energy. This is best shown by a graph of energy over time where Potential energy is a parabola opened down (frown face) and Kinetic energy is a parabola opened up (smiley face).
With this you can also note that Kinetic Energy + Potential Energy = mechanical energy. These two graphs added together should make a straight line for Mechanical energy (in simplistic demonstration).

Also, by conservation of energy, KEi+PEi= KEf+PEf Where PE is potential energy. Since the only potential energy in this specific problem after the ball is tossed is that of gravity then it would be PE=mgh (mass*gravity*height) so the higher the ball gets, the more potential energy it has, and the less kinetic energy it has.

∙ 12y agoIf a ball is thrown straight up, its kinetic energy is zero at its highest point and its
potential energy is maximum. In its return back down, its kinetic energy is recovered
at the expense of its potential energy.
If the ball is thrown into the air in a "cannon ball" fashion, the ball tends to follow a
parabolic path (only limited by air resistance). In this case you can think of two
components of the velocity of the ball. A parallel to the ground velocity component
vx, and a vertical velocity component vy. Air resistance aside, the x velocity component vx is kept constant, the y velocity component vy drops to zero at the ball
maximum height and recovers as the ball comes down, like in the case of the ball thrown straight up.

∙ 13y agowell when you throw a ball that is when it has the most speed so that would be the most energy and when they ball is mid way through the throw or toss it starts to slow down. hope this helps

Heat energy to kinetic energy to sound energy to what?
I do not have any answer concerning the converting of sound energy into kinetic energy. But concerning heat energy, the most common and most effective means is through a heat engine. It is a machine for changing heat into motion or kinetic energy. The most popular of these engines are the internal-combustion engine and the external-combustion engine.
Derivative of kinetic energy?
Kinetic energy is a measure of energy and is therefore measured in joules (J). In S.I. units, a J can be written in its most basic form as: (kg m^2)/(s^2) This is apparent from the kinetic energy equation: KE = (1/2) m v^2
Where does a skater have the most kinetic energy?
At rest at top of slope, it is all potential energy(mass * g * vertical distance to bottom of slope). Ignoring friction losses, this will translate to all kinetic energy at the bottom. kinetic energy = 0.5 * mass * velocity squaredexample:mass of sled + rider = 100 kgg = 9.82 ((m/s)/s) acceleration due to gravityvertical distance = 20 metresso:potential energy at slope top = 100 * 9.82 * 20 = 19 640 joulesso:kinetic energy at bottom = 19 640 joulesso :19 640 = 0.5 * 100 * velocity ^2so:velocity = square root (19 640 / (0.5 * 100))velocity = 19.82 metres / sec
What happens to kinetic energy and potential energy of a car when it accelerates up a hill?
What happens to kinetic energy when your car stops at the end of the track? It's all about energy? The first question to ask yourself is," What stops your car? Most people would say, "The brakes stop the car." What happens to the brake as the car is stopped? Due to friction, they heat up and the brake pads wear out? What does it mean for brake pads to wear out? The brake pads get thinner as they rub on the spinning rotor. What causes them to get thinner? The friction breaks the chemical bonds in the material of which they are made. The Kinetic energy is converted into heat and used to break the bonds between the molecules in the material of which the brake pads are made. If you push hard enough on the brake pedal, the tires will stop turning, and the car will skid to a stop. In this case, the tires will give off heat due to friction and the tires will wear thin as the chemical bonds between the molecules in the material of which they are made are broken. Good site for explanation of brakes! http://www.familycar.com/brakes.htm
This form of energy is produced by plants as a result of photosynthesis?
It cannot be certain as there is still alot left to learn about plants and their actions. The most supported idea is CHEMICAL KINETIC energy. This is because the chemical produced in photosynthesis is then transported to the other parts of the plants, therefore, CHEMICAL KINETIC energy.
Does kinetic energy have chemical energy?
no, kinetic energy is the energy below so if u hold a ball up in the air it has most potential energy but if u drop the ball the potential energy goes down and the kinetic energy goes up.
The ball has the most potential energy at point 3?
The ball has the most potential energy at the highest point of its trajectory

Consider al bouncing ball were would the ball have least gravitationl energy?
gravitational energy is the same as potential and kinetic energy. When the ball is further from the surface of the earth it will have the most potential energy and when the ball gets closer to the surface of the earth that potential energy turns into kinetic energy because it is being used to move the ball towards the surface.
Which item will have the greatest kinetic energy a marble a basketball a beach ball or a tennis ball?
If they're moving at the same speed, then the one with the most mass will have the most kinetic energy; that's probably the basketball.If they're not moving at the same speed, all bets are off.
As a rocket rises its kinetic energy changes. At the time the rocket reaches its highest point most of the kinetic energy of the rocket has been and mdash?
When an object - rocket or otherwise - rises, its kinetic energy gets converted to gravitational potential energy. At its highest point, if it rises directly upwards, all the kinetic energy will be converted to gravitational potential energy. However, its movement may also have a sideways component; in that case, not all the kinetic energy is converted to potential energy.
If you toss a ball in the air at what point does it have the most potential energy?
When the ball is in your hand, not moving
What sport involves transforming gravitational potential energy into elastic energy?
This can happen in many sports. One common example is anything that involves a ball - of the type that can bounce when they fall. In such a ball, when it falls down, gravitational potential energy is converted into kinetic energy; later, when it touches the ground, the kinetic energy is converted into elastic energy. When the ball bounces back, part of this elastic energy (typically, most of it) is converted back into kinetic energy.
Thermal energy is comprised of?
kinetic energy
When does a object have the most kinetic energy?
In the case of a falling object, the instant before the object hits the ground. U = KE + PE; PE=-KE . Inversely, the object has the highest potential energy (lowest kinetic energy) at the starting point of the fall.
Where does the pendelum posses the highest potential energy?
At it's highest point where it begins to come back down. It has 0 kinetic energy, so that is when it has the most potential.
Which state of energy has the most kinetic energy?
