Physics Test: Practice Questions On Moments, Levers And Gears! - Quiz

In this "Physics Test: Practice Questions On Moments, Levers, And Gears!" on the scientific topic of physics, we'll be taking a look at the moment of force – which is defined as the measure of its tendency to cause a body to rotate about a specific point of axis. One example you might find easiest to wrap your head around is the see-saw. Think of what causes the see-saw to balance and what tilts it to either side. What do you know about these moments? Take this quiz and find out.

Questions and Answers

1.

For a see-saw to balance, the anti-clockwise moment must equal the clockwise moment. A moment is another word for a turning effect. A see-saw is like a lever, turning around a pivot, also called a fulcrum. A lever is a simple machine which amplifies the effort force.
