# What is the gravitational potential energy of a 3 kg ball that is 1 meter above the floor?

## What is the gravitational potential energy of a 3 kg ball that is 1 meter above the floor?

(3) x (9.8) x (3 meters) = 88.2 joules.

## What is the potential energy if a body of mass 250 kg is at a height of 30 meters?

250×30=7500.

What is the potential energy of the ball?

It has only been converted into gravitational potential energy. Dropping the ball will release the stored energy; as the ball falls, it transforms the potential to a kinetic form as it moves. When the ball hits the ground, the kinetic energy will be absorbed by the ground as heat or released as sound that you can hear.

What is the kinetic energy of a 3 kilogram ball that is rolling?

What is the kinetic energy of a 3-kilogram ball that is rolling at 2 meters per second? KE= ½ m v2 = ½ (3kg) (2 m/s)2 = 6 Joules 8.

### How do you calculate potential energy loss?

The loss of gravitational potential energy from moving downward through a distance h equals the gain in kinetic energy. This can be written in equation form as −ΔPEg = ΔKE. Using the equations for PEg and KE, we can solve for the final speed v, which is the desired quantity.

### What is the potential energy if a body mass 250?

What is the potential energy of 3 kilograms?

In this example, a 3 kilogram mass, at a height of 5 meters, while acted on by Earth’s gravity would have 147.15 Joules of potential energy, PE = 3kg * 9.81 m/s 2 * 5m = 147.15 J. 9.81 meters per second squared (or more accurately 9.80665 m/s 2) is widely accepted among scientists as a working average value for Earth’s gravitational pull.

What is the kinetic energy of 10 kg?

For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s 2.

#### How is the potential energy of an object related to its mass?

The gravitational potential energy of this ball depends on two factors – the mass of the ball and the height it’s raised to. The relationship between gravitational potential energy and the mass and height of an object is described by the following equation: PE grav. = m * h * g

#### How to calculate the potential energy of gravity?

The easiest way to calculate gravitational potential energy is to use our potential energy calculator. This tool estimates the potential energy on the basis of three values. These are: The mass of the object. Gravitational acceleration, which on Earth amounts to 9,81 m/s². The height of the object.
