Equations with current values

W = Fd cos θ

Parallel component = F cos θ

Net work = sum of all work

Work–energy theorem: W net = ΔK

Values are physical calculations. Perspective, trails, and arrow lengths use conceptual visual scaling.

Chapters

Learning objectives

Calculate work by a constant force using W = Fd cos θ.
Explain positive, zero, and negative work.
Connect net work to kinetic-energy change.
Identify which force component transfers energy along a path.
Apply the model to ramps, lifting, carrying, and circular motion.

A reliable method

Choose the force whose work you want.
Measure displacement of its point of application.
Find the angle between force and displacement.
Use only the parallel component, F cos θ.
Multiply that component by displacement.
Add work from all forces to get net work and ΔK.

Examples demonstrated

Horizontal pulling: positive work.
Angled suitcase handle: only the forward component does work.
Ramp: applied force competes with gravity and friction.
Elevator: tension does positive work while gravity does negative work.
Rigid wall: force with no displacement does zero work.
Backpack: upward support is perpendicular to horizontal displacement.
Circular motion: radial force is perpendicular to instantaneous motion.

Common misconceptions

Exerting a force does not guarantee mechanical work; displacement is required.
The total force magnitude is not used when only its parallel component acts along displacement.
Negative work means energy leaves the object’s kinetic-energy store; work itself is not a direction.
Work is measured in joules, while force is measured in newtons.
