Understanding Moments in Physics

What is a moment in physics?

• A unit of distance

• A turning force around a pivot

• A type of energy

• A type of time measurement

How can two children of different weights balance on a seesaw?

• By sitting at the same distance from the pivot

• By the lighter child sitting closer to the pivot

• By the heavier child sitting closer to the pivot

• By both sitting on the same side

What unit is used to measure moments?

• Newton-meters

• Seconds

• Kilograms

• Meters

What must you remember when calculating moments?

• Use the horizontal distance

• Use the perpendicular distance

• Use the vertical distance

• Use the total distance

What must be true for a seesaw to be balanced?

• Moments do not affect balance

• Clockwise and anticlockwise moments must be equal

• Anticlockwise moments must be greater

• Clockwise moments must be greater
