An apple with a mass of 0.95 kilograms hangs from a tree branch 3.0 meters above the ground What is the potential energy of the apple?
PE=mgh Potential Energy = mass x gravity x height. PE=(5kg) x (9.8 m/s2) x (8m) which is the equation when you put the things you know into the right places. Gravity is the missing number, and that equals 9.8 m/s2
PE = mgh
PE = (5 kg)(9.8 m/s2)(8 m)
PE = (5 kg)(78.4 m2/s2)
PE = 392 kg m2/s2 or 392 joules
This block can perform 392 joules of work.
The potential energy of the apple can be calculated using the formula PE = mgh, where m is the mass of the apple (0.95 kg), g is the acceleration due to gravity (9.8 m/s^2), and h is the height above the ground (3.0 m). Substituting the values into the formula, the potential energy of the apple is 28.14 Joules.
Use the formula for potential energy, PE = mgh (mass x gravity x height). Gravity is about 9.8. Answer is in Joule.

Does a leaf on a branch have potential energy?
Yes, a leaf on a branch does have potential energy due to its position above the ground. When the leaf falls, this potential energy is converted into kinetic energy as it descends.
What forms of potential energy would be found on an apple on a branch of a tree?
The apple on a branch of a tree has gravitational potential energy due to its height above the ground. It also has elastic potential energy if the branch is bent under the weight of the apple.
What is the potential energy of a kilograms person that is W meters above ground?
The potential energy of a person standing W meters above the ground can be calculated using the formula: Potential energy = mass x gravity x height, where mass is in kilograms, gravity is approximately 9.8 m/s^2, and height is in meters.
What Forms of potential energy would be found in apple on a branch of a tree?
The apple on a branch of a tree would possess mainly gravitational potential energy, as it's elevated above the ground. It may also have elastic potential energy if the branch is bent from the apple's weight.
What if An apple with a mass of 0.95 kilograms hangs from a tree branch 3.0 meters above the ground. If it falls to the ground what is the kinetic energy of the apple just as it reaches the ground?
The potential energy of the apple while hanging is given by mgh, where m=0.95 kg, g=9.8 m/s^2, and h=3 m. At the moment it reaches the ground, all this potential energy will have converted to kinetic energy, thus the kinetic energy would be equal to the initial potential energy. Calculating mgh gives a potential energy of 27.93 J, which would be the kinetic energy just before hitting the ground.

What forms of potential energy would be found in an apple in a tree?
In an apple in a tree, potential energy forms include gravitational potential energy due to the apple's height above the ground, and elastic potential energy from the apple's position relative to the tree branch it's attached to.
What is the potential energy at the ground?
The potential energy at ground level is typically zero, as the reference point for potential energy calculations is often set at ground level. This means that any object at ground level would have zero potential energy due to its height above the ground.
A picture hanging on the wall has what energy?
It is higher from ground thus it contain potential energy.
How does a wooden arrow lying on the ground have potential energy?
No , it won't have potential energy. Potential energy is due to height.
Is anything that lifted off the ground has potential energy?
Yes, anything that is lifted off the ground gains potential energy due to its height above the Earth's surface. This potential energy can be converted into other forms of energy when the object falls back to the ground.
Does a rock have potential and kinetic energy as it hits the ground?
Yes, when a rock falls towards the ground, it has potential energy due to its position above the ground. As it falls, this potential energy is converted into kinetic energy, which is the energy of motion, until it finally hits the ground and transfers its energy upon impact.
What energy is used when skydiving?
Potential energy is converted to kinetic energy when skydiving. As the skydiver jumps from the plane, they have a high potential energy due to their height above the ground. This potential energy is then converted into kinetic energy as the skydiver accelerates towards the ground.
