# What is the real force?

A genuine force is one that operates on an object as a result of another thing. "An isolated item, apart from all other objects, experiences no true force." A force is said to be universal if it acts on all matter. Gravity is the most familiar example of a universal force.

Other forces are not as widespread but they are still present in certain areas and under certain conditions. For example, the electric force is responsible for the attraction between a charged particle and a conductor. This force is universal because it acts on all matter with a charge to within certain limits. The weak nuclear force is very powerful but it is only active inside particles such as atoms and electrons and it acts only within certain distances (nanometers). It is therefore considered to be a local force.

The strong nuclear force is even more powerful but it acts over much larger distances (fractions of a micron). It is therefore regarded as a grand-unified force since it unites the forces of gravity and electromagnetism.

Finally, there is the force that binds together molecules into compounds and keeps them together in solids, liquids and gases. This is called the chemical force or covalent force and it is extremely powerful but it is only active within certain distances (angstroms).

## What is the force behind the science definition?

The term "force" has a specific meaning in science. At this level, it is quite acceptable to refer to a force as a "push" or "pull." A force is not something that an item "has in it." Another object applies a force on one object. The concept of a force is not restricted to living or non-living entities. A force can be said to exist between two objects regardless of whether they are separated by space or not. For example, if I lift up my bookcase and throw it across the room, there is a force acting between me and the bookcase because we are not separated by space.

Science defines forces in three ways: 1 as a push or pull exerted on an object; 2 as a change in momentum of a body; 3 as the ability of two bodies to act on each other.

A force is anything that causes changes in energy. Energy is the ability to do work. So a force is anything that can cause things to move or interact with one another.

For example, if I jump up onto my desk, I apply a force on myself and everything else in my vicinity. This force causes me to rise into the air and land on my feet without being touched by any part of the desk. It also causes my books to fall off the shelf and hit the floor. Forces are all around us; they just need a way to go somewhere!

## How is a force created?

A force is a push or pull on an object caused by its contact with another thing. When two objects interact, a force is exerted on each of the items. Forces exist exclusively as a result of contact...

How do forces work? Consider the example of two cars driving down the road toward one another. Each car is driven by a person who wants to get home as soon as possible. They are both trying to go as fast as they can while still staying in their own lanes. And just like that, forces are at work between these two vehicles. One driver wants to move his car forward, another driver tries to stop him. If the first driver didn't try to resist the second's attempt to slow down the first will be unable to go as fast as he or she wanted. The first driver needs resistance so that he or she can go faster. Without it, the car would roll over before reaching its destination.

In physics, forces are defined as the cause of change in momentum or direction of motion. For example, when you jump off a cliff, you apply a force on yourself which causes your body to accelerate downward. This is called the falling force. Your body has more mass than air so it takes time for you to reach terminal velocity - about 100 kilometers per hour (60 miles per hour). At this speed, you would travel about 1 kilometer every second!
