Question

Define the following key-words

Magnetic force, Muscular force, Non-contact force, Pressure

​

Answer 1

Answer:

Magnetic force: the force exerted by a magnet on magnetic substances is called magnetic force

Muscular force: The force applied by a muscles of human or an animal is called muscular force

Non contact force : The forces that act on the objects when they are not in actual contact with each other are called non contact force

Pressure: ...........

$\huge\pink{❥Magnetic-Force}$

Magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. It is the basic force responsible for such effects as the action of electric motors and the attraction of magnets for iron.

$\huge\green{❥Muscular-Force}$

It is a force that results because of the action of muscles and is a contact force since there is contact between the surfaces. Muscular force is required whenever the movement of the body occurs.

$\huge\orange{❥Non-Contact\:Force}$

A non-contact force is a force which acts on an object without coming physically in contact with it. The most familiar non-contact force is gravity, which confers weight. In contrast a contact force is a force applied to a body by another body that is in contact with it.

$\huge\red{❥Pressure}$

Pressure is defined as the physical force exerted on an object. The force applied is perpendicular to the surface of objects per unit area. The basic formula for pressure is F/A (Force per unit area). Unit of pressure is Pascals (Pa). Types of Pressures are Absolute, Atmospheric, Differential, and Gauge Pressure.
