## What is the downward force on earth called?

gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth’s mass exerts on them.

**What is the downward force on an object?**

Weight of an object is a result of the Earth’s attraction downward. Weight is a downward force. Example: An astronaut in space has the same mass as he does on earth while having different weights. This is because there is a difference in gravity.

**Is gravity a real force?**

Gravity is most accurately described by the general theory of relativity (proposed by Albert Einstein in 1915), which describes gravity not as a force, but as a consequence of masses moving along geodesic lines in a curved spacetime caused by the uneven distribution of mass.

### Which force is pushing upward?

normal force

Since the block is not moving, these two forces must be equal and opposite to produce a net force of zero. Since normal force is pushing upward, it will be positive. (The force of gravity would be negative).

**What force keeps you on the ground?**

gravity

The answer is gravity: an invisible force that pulls objects toward each other. Earth’s gravity is what keeps you on the ground and what makes things fall. Anything that has mass also has gravity.

**What kind of force acts on the object that makes it move downward every time it is tossed upward?**

Gravity

Gravity is the downward force upon a projectile that influences its vertical motion and causes the parabolic trajectory that is characteristic of projectiles. A projectile is an object upon which the only force is gravity.

## What are the 4 forces of nature?

fundamental force, also called fundamental interaction, in physics, any of the four basic forces—gravitational, electromagnetic, strong, and weak—that govern how objects or particles interact and how certain particles decay. All the known forces of nature can be traced to these fundamental forces.

**What is upwards force?**

The upward force on an object at rest is called the Normal force and is always perpendicular to the surface. If you recall from Newton’s Third law, “Every action has an equal and opposite reaction.”
