mass = 20 kg
height = 100 m
acceleration due to gravity = 10 m/s2
U = mgh
= 20 X 100 X 10
= 20000 J
or
= 220kJ

The potential energy of the rock can be calculated using the formula: Potential energy = mass * gravity * height. Given the mass of 20 kg, gravitational acceleration as 9.8 m/s^2, and height of 100 meters, the potential energy of the rock would be 20 kg * 9.8 m/s^2 * 100 m = 19600 J.

How much energy (in Joules) does a 3-kg vase possess when it's placed on shelf 2.5 meters above the ground?
The potential energy of the 3-kg vase can be calculated using the formula: potential energy = mass * gravity * height. With a mass of 3 kg, gravity as 9.81 m/s^2, and a height of 2.5 meters, the potential energy would be approximately 73.58 Joules.
How does height affect the amount of potential energy of an object?
Height affects the potential energy of an object through gravitational force. The higher the object is lifted, the more potential energy it has due to the increased distance it can fall under gravity. The potential energy of an object is directly proportional to its height above the reference point.
What two factors does potential energy depend on?
Potential energy depends on the object's position and its mass. The higher an object is placed above the ground and the more massive it is, the greater its potential energy.
How does height affect potential energy and kinetic energy?
Height directly affects gravitational potential energy, since this energy is equal to mgh (mass x gravity x height). Height does not affect kinetic energy, which depends on the speed, not on the height. Except indirectly - for example, if an object is falling down, its speed will usually increase.
What is a second factor that affects gravitional potential energy?
Another factor that affects gravitational potential energy is the height or distance the object is from the reference point. The higher an object is placed, the greater its gravitational potential energy will be.

How much energy in joules does a 3 kg vase possess when its placed on a shelf 2.5 meters above the ground?
The potential energy of the vase can be calculated using the formula: Potential Energy = mass * acceleration due to gravity * height. Plugging in the values: Potential Energy = 3 kg * 9.8 m/s^2 * 2.5 m = 73.5 Joules.
Example for gravitatinal potential energy?
A simple example of gravitational potential energy is a book placed on a table. The book has potential energy due to gravity pulling it downwards. As the book is lifted higher, its potential energy increases because it has the potential to fall from a greater height and do more work as it falls.
What everyday object uses all forms of potential energy?
An everyday object that uses all forms of potential energy is a wind-up alarm clock. It stores energy in the form of mechanical potential energy when it is wound up, gravitational potential energy when placed at a height, and elastic potential energy in its spring mechanism.
What is potential energy result?
Potential energy is the energy that an object possesses due to its position or configuration. When an object is placed at a certain height or stretched or compressed, it has potential energy that can be converted into kinetic energy as the object moves or changes position. The potential energy of an object represents the energy stored within it that can be released and used to do work.

How much energy in Joules does a 3 kg vase possess when it's placed on a shelf 2.5 meters above the ground?
Use the formula PE = mgh (potential energy = mass x gravity x height). Gravity is approximately 9.8 m/s2. Answer will be in Joule.
If to vases are side-by-side on a shelf how could one have more potential energy?
One vase could have more potential energy if it is placed higher up on the shelf compared to the other vase. Potential energy is directly related to an object's height above the ground, so the higher the vase is placed, the more potential energy it will have due to its greater distance from the ground.
