To be honest, I have no idea how to start this problem.
An external force is a force that acts on an object from outside of the system it is in. It can cause a change in the object's motion or shape.
An external force works on a particle by exerting a force on it, causing it to move in a certain direction or change its velocity. This can lead to a change in the particle's kinetic energy.
Examples of external forces include gravitational forces, electric and magnetic forces, friction, and air resistance. These forces can affect the motion or behavior of a particle or object.
The work done by an external force on a particle is calculated by multiplying the magnitude of the force by the displacement of the particle in the direction of the force. This can be represented by the equation W = Fd.
Understanding external forces is important in science because it allows us to predict and control the behavior of objects and particles. It also helps us to understand the laws of motion and how energy is transferred and transformed in different systems.
