Types of Forces

Define nuclear force.

The meaning of the inertia is resistance to change.

Explain the concept of inertia.

Earth is an inertial frame.

Newton's laws of motion are applicable in inertial frame.

Define the resultant force of a body.

Resultant forces are also called as net forces of the body.

Friction is a component of total reaction force.

Explain frictional force with an example.

What are the four fundamental forces?

How does fundamental force classified on the basis of their work?

The rough surface of a horizontal table offers a definite maximum opposing force to initiate the motion of a block along the table, which is proportional to the resultant normal force given by the table. Forces $\mathrm{F}1$ and $\mathrm{F}2$ act at the same angle $\mathrm{\theta }$ with the horizontal and both are just initiating the sliding motion of the block along the table. Force $\mathrm{F}1$ is a pulling force while the force $\mathrm{F}2$ is a pushing force. $\mathrm{F}2 > \mathrm{F} 1$ , because

Consider following forces: $\left(\mathrm{w}\right)$ Force due to tension along a string,$\left(\mathrm{x}\right)$ Normal force given by a surface, $\left(\mathrm{y}\right)$ Force due to air resistance and $\left(\mathrm{z}\right)$Buoyant force or upthrust given by a fluid. Which of these are electromagnetic forces?

What do you mean by force? Discuss in brief the various types of forces.

The force, that is not displacement dependent is:

Which one of given force is not example of internal force?

Which of the given force is not external force?

What is SI unit of force?

When cars drive on icy roads, the friction between the car and the road is reduced. If the friction was reduced to zero, which statement describes the motion of the car along a flat icy road?

The forces, which meet at one point but their lines of action do not lie in one plane, are called:-
