What is the equation for work when the force F and the displacement s are constant and the angle θ between them is also constant?
What is the equation for work when the force F and the displacement s are constant and the angle θ between them is also constant?
- $W = |F||s|$
- $W = |F||s|\cos(\theta)$ (correct)
- $W = |F||s|\sin(\theta)$
- $W = |F| + |s| + \theta$
In which scenario does a force do negative work?
In which scenario does a force do negative work?
- When it is applied with a greater force
- When it has a component opposite to the direction of the displacement (correct)
- When the displacement is zero
- When it has a component in the direction of the displacement
