What is the formula for work when the force F and displacement s are constant and the angle θ between them is also constant?
What is the formula for work when the force F and displacement s are constant and the angle θ between them is also constant?
- $W = |F| + |s| + \theta$
- $W = |F||s|\cos(\theta)$ (correct)
- $W = \frac{|F|}{|s|}\cos(\theta)$
- $W = |F||s|\sin(\theta)$
What type of work does a force do if it has a component in the direction of the displacement?
What type of work does a force do if it has a component in the direction of the displacement?
