Force of gravity from different heights

In summary, the force of gravity is a natural phenomenon that causes objects with mass to be attracted to one another. It decreases as you move further away from the center of the Earth and the relationship between height and gravitational force is inverse. On other planets, the force of gravity is dependent on their mass and size, and it affects all objects equally, regardless of their mass. However, objects dropped from different heights will reach the ground with different velocities due to the greater distance they had to accelerate.

How do I find the difference in gravity pull on a object dropped from 1km, 10km and 100km based on the objects mass (such as Earth vs the moon)

e: Don't care about drag

You can use the equation:

F = (-G x m1 x m2) / r^2

F is Force
G is Gravitational constant (6.7x10^-11) (Make it negative to show attraction)
m1 is the mass in kg of an object
m2 is the mass in kg of another object
r is the radius or the distance in meters between the objects.

Hope this helps!
 

Related to Force of gravity from different heights

1. What is the force of gravity?

The force of gravity is a natural phenomenon that causes objects with mass to be attracted to one another. It is a fundamental force of nature and is responsible for keeping planets in orbit around the sun, and objects on Earth from floating away into space.

2. How does the force of gravity change at different heights?

The force of gravity decreases as you move further away from the center of the Earth. This is because the Earth's mass is concentrated at its core, and the force of gravity is strongest at the surface. As you move higher above the Earth's surface, the gravitational pull decreases.

3. What is the relationship between height and gravitational force?

The relationship between height and gravitational force is inverse. As height increases, the force of gravity decreases. This is due to the inverse square law, which states that the force of gravity is inversely proportional to the square of the distance between two objects.

4. How does the force of gravity differ on other planets?

The force of gravity on other planets is dependent on their mass and size. For example, Jupiter is much larger than Earth and has a greater mass, so the force of gravity on Jupiter is stronger than on Earth. The force of gravity also varies with distance from the planet's center, just like on Earth.

5. How does the force of gravity affect objects dropped from different heights?

The force of gravity affects all objects equally, regardless of their mass. So if two objects are dropped from different heights, they will both accelerate towards the ground at the same rate. However, the object dropped from a greater height will have a higher velocity when it reaches the ground, due to the greater distance it had to accelerate.
