In physics, a force can be broken down into components each acting in different directions. This means that when a force is applied to an object, not only is the total force important, but also the effect of the force in specific directions.
To calculate work done by a force when there is an angle involved, we need to consider which part of the force is actually making the object move.
The component of the force that contributes to work is the one acting in the same direction as the displacement.
This is known as the parallel component of the force.
- Only this parallel component does work on the object.
- Forces perpendicular to the displacement do not contribute to work.
Understanding these components helps us in solving problems involving work and energy effectively.
