## What happens to an object of the clockwise and anticlockwise forces are balanced?

If an object is balanced, **the total clockwise moment about a pivot is equal to the total anticlockwise moment about that pivot**.

## When a body is balanced the total clockwise moment about a point equals the total anticlockwise moment about the same point?

The Principle of Moments states that when a body is balanced, the total clockwise moment about a point equals the total anticlockwise moment about the same point. **Moment =force F x perpendicular distance from the pivot d**.

## When a seesaw is the clockwise moments equal the anticlockwise moments?

The longer the distance the greater the moment. This is why it is easier to turn a long spanner than a short one. **When an object is balanced**, the anticlockwise moment is equal to the clockwise moment. The clockwise and anticlockwise moments are the same, so the seesaw is balanced, or in equilibrium.

## What is the rule of balance?

Conclusion: On a separate sheet of paper, make a claim in which you mathematically state the rule of balance – that is, the rule that **one must use to determine if two weights placed on opposite sides of the fulcrum will balance each other.**

## Who is trying to turn the seesaw clockwise?

Moments Acting On A Seesaw

Both people exert a downward force on the seesaw due to their weights. **Person A’s weight** is trying to turn the seesaw anticlockwise whilst person B’s weight is trying to turn the seesaw clockwise. Therefore seesaw is in equilibrium.

## Do the clockwise and anticlockwise moments add up to zero?

So, basically the principle of moments, defines the null addition of all the rotational effects of forces acting, hence the clockwise and anticlockwise moments of forces **add up to zero**.

## Are clockwise moments positive?

**If a moment is moving ANTICLOCKWISE it is considered a POSITIVE moment**. If a moment is moving CLOCKWISE it is considered a NEGATIVE moment.

## How do you identify clockwise and anticlockwise moments?

**Moments**

- The anticlockwise moment acts downward on the left, and the clockwise moment acts downwards on the right.
- The perpendicular distance is the shortest distance between the pivot and the line of action of the force.
