## What does gravitational potential energy depend on?

Thus, we can say that Gravitational potential energy depends upon the following factors: Mass of the object. Height of the object. Value (strength) of the gravitational field.

## What is the acceleration of the meteoroid due to the gravitational force exerted by the planet?

Final answer: The acceleration of the meteoroid due to the gravitational force of the planet, which has the same mass as Earth and a radius 90% that of Earth’s, and is 600 km away from the meteoroid, is approximately 9.81 m/s², the same as Earth’s acceleration due to gravity.

## Does gravitational potential energy depend on direction?

The change in gravitational potential energy (ΔPEg) between points A and B is independent of the path. The equation ΔPEg = mgh applies for any path that has a change in height of h, not just when the mass is lifted straight up.

## What are 3 examples of gravitational potential energy?

- A raised weight.
- A car that is parked at the top of a hill.
- A yoyo before it is released.
- A book on the table before it fails.
- Water flowing from the tap uses gravitational energy.
- We walk, sit and stand comfortably due to gravitational force.

## What happens to the speed of meteoroids as they enter the Earth’s atmosphere?

Space.com: “Perseid meteoroids (which is what they’re called while in space) are fast. They enter Earth’s atmosphere (and are then called meteors) at roughly 133,200 mph (60 kilometers per second) relative to the planet.

## What is the acceleration of the meteoroid?

Question | Answer |
---|---|

A meteoroid changed velocity from 1.0 km/s to 1.8 km/s in 0.03 seconds. What is the acceleration of the meteoroid? | 26.7 km/s² |

A car going 50mph accelerates to pass a truck. Five seconds later the car is going 80mph. Calculate the acceleration of the car. | 6 mph/s |

## What forces act on a meteor as it falls toward Earth?

When the meteor gets close to Earth, the pull of Earth’s gravity causes it to accelerate. When it enters the atmosphere, it slows down because the force of friction is pushing in the other direction. This process speeding up and slowing down agrees with Newton’s second law.

## Can gravity do negative work?

If the object moves upward, the work done by gravity will be negative as the direction of gravity is opposite of the displacement. Whereas if an object moves downwards, the work done by gravity will be positive as the gravity and the displacement will be in the same direction.

## Why gravitational potential is always negative?

At the Earth’s surface, gravitational potential energy is negative because the gravitational field performs work in bringing a mass from infinity, i.e. work must be performed on a body if it is removed from the earth’s gravitational field. As a result, potential energy is negative.

## What is the difference between gravitational potential and potential energy?

Gravitational Potential is equal to the potential energy of the unit mass kept at that point. Gravitational Potential Energy is defined as the energy stored in an object that is held in a vertical position due to the force of gravity working on it to pull it down.

## What does gravitational potential energy not depend on?

From the equation, potential energy is proportional to M and inversely proportional to r . It does not depend on G because the universal gravitational constant is well, constant.

## Does gravitational potential energy depend on weight and height?

Gravitational potential energy depends upon the mass and height of the body.

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

As most of this GPE gets changed into kinetic energy, the higher up the object starts from the faster it will be falling when it hits the ground. would need more GPE to reach the same height. So a change in gravitational potential energy also depends on the mass of the object that is changing height.

## Why does gravitational potential energy depend on mass?

The higher the object is lifted and the greater its mass, the more potential energy it will possess. In summary, gravitational potential energy depends on both mass and height because these two factors affect the strength of the gravitational energy between objects.
