# A simple question about gravity.

Is the length of time for which an object is falling directly proportional to the force it hits the ground with?

The speed of a falling object is proportional to time (assuming no air resistance) V=u+gt

The force it hits the ground with depends on how quickly it stops.
But if we assume the stopping time is the same then F=ma and a (deceleration) is speed/stopping time

So yes.

Thanks for the help :)

In the context of things falling close to the Earth's surface, yes.

## 1. What is gravity?

Gravity is a fundamental force of nature that causes objects with mass to attract each other. It is the force that keeps planets in orbit around the sun and objects on Earth from floating away into space.

## 2. How does gravity work?

Gravity works by creating a force between objects with mass. The strength of this force depends on the mass of the objects and the distance between them. The larger the mass of an object, the stronger its gravitational pull.

## 3. Who discovered gravity?

Sir Isaac Newton is credited with discovering gravity in the late 17th century. However, the concept of gravity has been observed and studied by many ancient civilizations, including the Greeks and Egyptians.

## 4. What is the difference between gravity and gravitational pull?

Gravity and gravitational pull are often used interchangeably, but they are slightly different. Gravity is the force that attracts objects with mass, while gravitational pull is the strength of that force. So, gravity is what causes objects to be pulled towards each other, while gravitational pull is the measure of how strong that pull is.

## 5. Can gravity be manipulated?

Currently, we do not have the technology to manipulate gravity. However, there are theories and ongoing research on the concept of anti-gravity and ways to potentially control or negate the effects of gravity.
