Define force and explain its representation mathematically.

Force is a mechanical quantity that changes or tends to change the motion or shape of a body. It is represented mathematically as a vector and has a point of application.

What is the difference between direct and indirect methods of measuring force?

Direct methods involve a direct comparison with a known gravitational force, while indirect methods involve measuring other quantities and calculating force indirectly.

How can force be measured using direct methods?

Force can be measured using direct methods by comparing it with the gravitational force on a standard mass, such as by using a balance.

What is the formula to calculate the force experienced by a body in the earth's gravitational field?

<p>The force experienced by a body in the earth's gravitational field is given by the formula F = ma, where F is the force, m is the mass of the body, and a is the acceleration due to gravity.</p> Signup and view all the answers
