Question

A force acts on a particle that undergoes a displacement.

Answer 1

An F Vector Force

Example:

The work done by the force on the particle is 1 J.

The angle between the force and the displacement is 81.87⁰.

The given parameters;

F = (4i - 3j)

displacement of the particle, s = (i + j)

The work done by the force on the particle is calculated as follows;

The angle between the force and the displacement is calculated as follows;
