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

In this quiz 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?
