## What is force and its types

Force is a physical cause that can change the state of motion or the dimensions of an object. There are two types of forces based on their applications: Contact Force. Non-Contact Force.

## What is force in simple words

In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate. Force can also be described intuitively as a push or a pull.

## What are 5 units of pressure

The most frequently used units of pressure are pascal (Pa), kilopascal (kPa), megapascal (MPa), psi (pound per square inch), torr (mmHg), atm (atmospheric pressure) and bar.

## How we can classify the force

Contact forces can be classified according to six types: tensional, spring, normal reaction, friction, air friction, and weight. Noncontact forces: Forces that take place when two objects do not touch. These forces can be classified according to three types: gravitational, electrical, and magnetic.
