## What is the formula of gravitational?

We can do this quite simply by using Newton’s equation: forcegravity = G × M × mseparation2 . Suppose: your mass, m, is 60 kilogram; the mass of your colleague, M, is 70 kg; your centre-to-centre separation, r, is 1 m; and G is 6.67 × 10 11 newton square metre kilogram2.

## What is gravitational potential energy GCSE?

When an object is lifted in a gravitational field , energy is transferred to a gravity store. This store is called gravitational potential energy . gravitational potential energy = mass × height × gravitational field strength (g)

## What are 2 examples of gravitational energy?

Examples of Gravitational Potential EnergyA raised weight.Water that is behind a dam.A car that is parked at the top of a hill.A snow pack (potential avalanche)A yoyo before it is released.River water at the top of a waterfall.A book on a table before it falls.A child at the top of a slide.

## What is work formula?

Work is done when a force that is applied to an object moves that object. The work is calculated by multiplying the force by the amount of movement of an object (W = F * d).

## Is GPE equal to ke?

If an object, such as a ball is lifted above the ground it has gravitational potential energy. The gravitational potential energy is converted to kinetic energy .

## What is an example of GPE?

If an object is lifted, work is done against gravitational force. The object gains energy. For example, Book C would gain GPE if it were lifted onto the higher book shelf alongside Books A and B. For example, a book with a mass of 0.25 kg is lifted 2 m onto a book shelf.

## Where is gravitational potential energy stored?

Figure 1. (a) The work done to lift the weight is stored in the mass-Earth system as gravitational potential energy.

## What is the SI unit of gravitational force?

In SI units, G has the value 6.67 × 1011 Newtons kg2 m2. The direction of the force is in a straight line between the two bodies and is attractive. Thus, an apple falls from a tree because it feels the gravitational force of the Earth and is therefore subject to “gravity”.

## What are the 3 laws of gravity?

Newton’s Three Laws of MotionEvery object in a state of uniform motion will remain in that state of motion unless an external force acts on it.Force equals mass times acceleration [ ].For every action there is an equal and opposite reaction.

## What is the Newton formula?

1 Newton = 1 kg • m/s2 One Newton is defined as the amount of force required to give a 1-kg mass an acceleration of 1 m/s/s.
