# What is the potential energy of a rock that weighs 150 Newtons?

Answer: The potential energy of the rock is 30,000 J.

## How do you calculate potential energy in physics?

The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.

## What are 10 examples of potential energy?

• Pendulum.

## What is potential energy in physics with examples?

potential energy, stored energy that depends upon the relative position of various parts of a system. A spring has more potential energy when it is compressed or stretched. A steel ball has more potential energy raised above the ground than it has after falling to Earth.

## How do you calculate potential energy examples?

1. PE = m g h.
2. = 2 kg × 9.8 m/s2 × 0.4 m.
3. = 7.84 kg m2/s2
4. = 7.84 J.

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

We have to calculate the potential energy of the body for this formula. We can calculate the potential energy and so u equal to m g h, equal to 250 into 9.8 into 30 into 73500 joules. Hence the potential energy of the body will be 73500 joules and that’s the required.

## What is the potential energy of a 3kg ball that is on the ground?

In conclusion, the ball has no potential energy.

## What are the 4 example of potential energy?

Energy due to the position is called potential energy. P.E is the type of mechanical energy, Coiled spring, raised hammer, stretched rubber band are some examples of potential energy.

• A child at the top of a slide.
• Ripe fruit before it falls.

## What are the 3 main types of potential energy?

There are three main types of potential energy: elastic potential energy, gravitational potential energy, and chemical potential energy. Elastic potential energy is stored in objects that can either be stretched or compressed.

## What is the 5 potential energy?

There are several forms of potential energy including gravitational, magnetic, electrical, chemical, and elastic potential energy.

## What is potential example?

The definition of potential is having the power or being capable of happening. An example of potential is dinner plans that are not yet definite.

## How do you find potential energy between two charges?

So to find the electrical potential energy between two charges, we take K, the electric constant, multiplied by one of the charges, and then multiplied by the other charge, and then we divide by the distance between those two charges.

## What is the formula of potential energy of electron?

The potential energy of the electron in the field of the positive proton point charge is U(r) = -qeV(r) = – keqe2/r. The total energy is the sum of the electron’s kinetic energy and its potential energy.

## What is the potential energy if a body of mass 50 kg is at a height of 30 m?

∴ The potential energy of a body is 4900 J .

## How much potential energy an object of mass 50 kg can possess at the height 12 m while g 10 m s2?

CALCULATION: Given that: the mass of body 50 kg, Height covered 10 m, g = 10 m/s2. P. E. = m × g × h = 50 × 10 × 10 = 5000 Joule.

## What is the potential energy of a 2kg mass having a height of 40m from its reference point?

m = 2 kg, h = 40 m, and, g = 9.8 m/s². ⇒ U = 784 J.

## What is the potential energy of a 150 kg?

Find the height of the box above the ground. Take g=9.8Nkg−1. Q. The gravitational potential energy of a box of weight 150 KGF is 1.5×104J.

## What is the potential energy of the car on top of a 72 m hill and weighs 966 N?

PE= Fwh = (72 m) (966 N) = 69552 Joules 7.

## What potential energy is acquired by a hammer with a mass of 0.75 kg when raised 0.35 m?

Therefore, the potential energy acquired by the hammer is 2.57 J.

## Why does gravitational potential energy depend on both mass and height?

The law of gravity states that the gravitational potential energy for an object must be equal to the amount of work done against gravity to move an object to a certain location. This is why gravitational potential energy depends both on height and acceleration due to gravity, g.
