Which of the two objects has more gravitational potential energy?

The more mass an object has, the more energy it stores. A 20 kg mass stores twice as much gravitational potential energy as a 10 kg mass at the same height. The higher up an object is, the more energy it stores. A mass 10 m above the ground stores twice as much energy as the same mass only 5 m above the ground.

When comparing 2 objects of the same mass which one has the greatest gravitational potential energy?

Higher objects (with further to fall) have greater potential energy. The heaviest of 2 objects at the same height has the greatest gravitational potential energy.

Which has a greater effect on gravitational potential energy height or mass?

The higher up an object is the greater its gravitational potential energy. This is because a tree has more mass, so it needs to be given more gravitational potential energy to reach the same height. So a change in gravitational potential energy also depends on the mass of the object that is changing height.

Does two objects with the same mass must have the same gravitational potential energy?

Yes they will have same gravitational potential energy. Others will be equal if the conditions are same.

Which of the following has the highest potential energy?

solid state of matter
The solid state of matter has the greatest potential energy.

What are 2 examples of gravitational energy?

Examples of Gravitational Potential Energy

• A raised weight.
• Water that is behind a dam.
• A car that is parked at the top of a hill.
• 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.
• Ripe fruit before it falls.

What is the relationship between height and gravitational potential energy?

There is also a direct relation between gravitational potential energy and the height of an object. The higher that an object is elevated, the greater the gravitational potential energy. These relationships are expressed by the following equation: PE grav = mass • g • height

How can the potential energy of a test mass be negative?

If a test mass moves from a point inside the gravitational field to the other point inside the same gravitational field of source mass, then the change in potential energy of the test mass is given by; > r f then ΔU is negative.

What is the energy of gravity between two objects called?

U = potential energy of gravity between two objects G = the universal gravitational constant, G = 6.673 x 10 -11 (N∙m 2 )/kg 2 r = the distance between the centers of mass of the two objects 1) Two asteroids are drifting away from each other.

How do you find the potential energy of gravity in space?

In space, it is possible to find the potential energy of gravity between two objects separated by a distance. This potential energy formula contains a constant, G, which is called the “universal gravitational constant”. Its value is = 6.673 x 10 -11 (N∙m 2 )/kg 2 . The unit of potential energy is the Joule (J), where 1 J = 1 N∙m = 1 kg m 2 /s 2 .
