One common mistake people make about work in physics is thinking it just means hard physical effort.
But in physics, "work" has a special definition. It happens when you apply a force to an object and that object moves in the direction of the force.
So, if you push a box and it doesn't move, then, by physics rules, you haven't done any work!
Another misunderstanding is that work depends only on how hard you push.
Actually, work is figured out using this formula:
Work = Force × Distance × cos(θ)
In this formula, θ (theta) is the angle between the way you are pushing and the way the object is moving.
If you push at an angle or if there’s no movement, the amount of work done can be less than what you expected.
Many people also think that energy and work are the same thing.
While they are connected, work measures how energy is transferred when something moves.
Understanding these ideas helps clear up confusion about energy and work in physics!
