What affects gravity of an object?

Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is. Earth’s gravity comes from all its mass.

What variables affect gravity and why?

Gravity is affected by the size of an object and the distance between the objects. When the mass of an object increases the force of gravity increases as well. If an object’s weight is greater than the other object’s weight, then the object with the greater weight will land first.

How can height affect the force of gravity?

gravity increases with height. gravity is significantly less on high mountains or tall buildings and increases as we lose height (which is why falling objects speed up) gravity is caused by the Earth spinning. gravity affects things while they are falling but stops when they reach the ground.

How does distance affects gravity?

Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.

How does the force of gravity affect falling object?

Gravity is a force that pulls objects down toward the ground. Gravity causes an object to fall toward the ground at a faster and faster velocity the longer the object falls. In fact, its velocity increases by 9.8 m/s2, so by 1 second after an object starts falling, its velocity is 9.8 m/s.

Does gravity affect the air we breathe?

We breathe by expanding our lungs. As long as the air around us is thick enough we can breathe, regardless of gravity. On Earth, gravity is what holds our atmosphere. When astronauts go into space they can breath, because their space ships and space suits keep the air around them, even though gravity is very weak.

What are 2 factors that affect the strength of gravity?

When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.
