Suppose that a heavy person and a light person are balanced on a seesaw made of a plank of wood. each person now moves in toward the pivot point a distance of 25 cm. what effect will this have on the balance of the seesaw?

the seesaw will still be balanced, nothing will happen to it

Explanation:

the principle of moment states that for a body to be in equilibrium the sum of anticlockwise moment must be equal to the sum of anticlockwise moment

also

The sum of upward forces must be equal to the sum of downward forces

a=weight of the heavy person

b=weit of the lit person

x=distance of the heavy person from the fulcrum

y=distance of the lit person from the fulcrum

now that they both moved 25cm towards the pivot

a*(x-25)= b*(y-25)1
