Answer 1

Answer:

Answer:

━━━━━━━━━━━━━━━━━━━━━━━━━━

Force:

Force is a physical quantity defined as a push or pull on a body. Force is an external agent in the form of push or pull. force can be different types and can produce different effects. force is always applied in a particular direction.

━━━━━━━━━━━━━━━━━━━━━━━━━

Types Of Force:

As we know that force is a push or pull. It is caused by the interaction of two objects. as soon as this interaction ceases, the object no longer experience the force.

Some forces can be felt easily, while others are difficult to spot. Different types of interactive forces can be categorised as non- contact and contact force.

Contact Forces:

This forces come into play only when bodies are in contact with each other. For example, when one body is sliding over another, contact forces are acting between them. Whether the bodies will move slow or fast will depend on the magnitude of contact force acting on them. Some important Contact Forces are:

✵Muscular Force

✵Muscular Force

Non-Contact Forces:

These are the forces that come into play when interacting bodies are not in contact with each other or at a distance. it is also referred to as action at a distance. Some important Non- Contact Forces are:

✵Gravitational Force

✵Electrostatic Force

✵Magnetic Force

Force can be classified into 2 types

i) Contact Force

Ans : Forces which acts on a body when a body is contact with another body is called contact force

ii) Non Contact Force

Ans : Forces which acts on a body when a body is not contact with another body is called non contact force.

Types of Contact Forces

i) Normal Force

Ans : If the contact forces between the bodies is perpendicular to the surface in contact are known as normal force

ii) Force of Friction

Ans: Two bodies placed in contact can also exert forces parallel to the surface in contact such a force is called force of friction.

iii) Muscular Force

Ans : Force exerted by muscles are called Muscular force.

Types of Non Contact Force

i) Gravitational Force

Ans The force of attraction between any two particles in the universe is called gravitational force

ii) Electrostatic Force

Ans: The force exerted by A charged body on another charged or uncharged body

iii) Magnetic Force

Ans : The force exerted by magnet is called magnetic force.
