Understanding Moments and Equilibrium

What is the effect called when a force causes an object to turn around a pivot?

• Gravity

• Moment

• Torque

• Inertia

In the context of moments, what is the unit of force?

• Pascals

• Joules

• Watts

• Newtons

Why are door handles placed far from the pivot?

• To balance the door

• To make the door heavier

• To increase the moment

• To reduce the force needed

Which of the following is NOT a factor affecting the moment?

• Distance from pivot

• Direction of force

• Force applied

• Weight of the object

What is the primary purpose of using long-handled tools?

• To increase the force applied

• To increase the distance from the pivot

• To decrease the weight of the tool

• To make the tool more durable

If a person weighing 500 newtons is 2 meters from the pivot, what is the moment?

• 2000 newton meters

• 500 newton meters

• 1000 newton meters

• 250 newton meters

What is the moment if a force of 600 newtons is applied 2 meters from the pivot?

• 300 newton meters

• 1200 newton meters

• 600 newton meters

• 1800 newton meters

What is the moment if a force of 450 newtons is applied 3 meters from the pivot?

• 1200 newton meters

• 1500 newton meters

• 900 newton meters

• 1350 newton meters

What happens to a seesaw if the clockwise and anti-clockwise moments are equal?

• It moves clockwise

• It falls over

• It moves anti-clockwise

• It remains balanced

In a balanced seesaw, what does the law of moments state?

• The pivot is at the center

• The sum of forces is zero

• The sum of clockwise moments equals the sum of anti-clockwise moments

• The seesaw will always tilt
