Answer:
When one object interacts with another causing a push or pull, it means that we are dealing with what is called force.
There are various types of force. Let's see:
- Frictional
- Gravitational
- Tension
- Electrical
- Normal
- Magnetic
- Air resistance
- Applied
- Spring
We human beings are constantly in contact with some of these forces at some time of the day, let's see just some of them that will serve as an example for this exercise:
APPLIED FORCE:
In the case of this exercise, we have the applied force, which is what a person performs to an object. Suppose we push a chair in order to sit, that force made by pushing is what is known as the applied force.
GRAVITATIONAL FORCE:
This force is possessed by all of us who inhabit the earth, be they animals, people or objects. It is the force that keeps us on the ground and works in such a way that due to gravity, a force "pulls us down" towards the center of the earth.
NORMAL FORCE:
It is the force that we do when leaning on an object that is on a stable surface. For example if we are sitting in a chair, that push would be an example of normal force.
