Turning effect of forces outcomes6 objectives
- Explain the concept of the moment of a force as an indicator of its ability to cause rotation, and provide common examples from daily life.
- Define the moment of a force using the formula moment = force × perpendicular distance from the pivot, and be able to recall and apply this formula.
- Utilize the principle of moments in scenarios where there is one force on each side of the pivot, including the balancing of a beam.
- Recognize that an object is in equilibrium when there is no net force and no net moment acting on it.
- Apply the principle of moments to various scenarios, including those involving multiple forces on either side of the pivot.
- Outline an experiment that shows there is no resultant moment acting on an object that is in equilibrium.
