What is the value of potential energy of a mango on a tree before it fells?
To determine the value of potential energy of a mango on a tree before it falls, we need to consider two factors: the mass of the mango and its height above the ground. Potential energy is calculated using the equation PE = mgh, where PE represents potential energy, m is the mass in kilograms, g is the acceleration due to gravity (approximately 9.8 m/s^2), and h is the height in meters.
To find the mass of the mango, we need a balance or a weighing scale. Place the mango on the scale and record the mass in kilograms.
Next, we need to measure the height of the mango from the ground. Use a measuring tape or ruler to measure the vertical distance from the base of the tree to the mango. Make sure to convert the measurement to meters.
Once you have the mass and height, you can calculate the potential energy using the equation PE = mgh. Multiply the mass (in kg) by the acceleration due to gravity (9.8 m/s^2) and the height (in meters). The resulting value will be the potential energy of the mango on the tree before it falls.
m g h is the potential energy on the branch if you define h, height, as zero on the ground.
All you can say about potential is difference. You have to pick a spot where you call it zero.
In the case of a fall out of a tree, you usually say zero at the ground. However if it fell in a
hole you could say zero at the bottom of the hole.
