Question

During her gymnastics practice, Zoya was finding it difficult to maintain her balance on the balancing beam. Her coach tried to explain to her about basic principles of equilibrium.

According to the principles of equilibrium Centre of gravity plays a very important role.

1. The nearer the Center of Gravity to the Center of the base of support the more will be the ______.
2. The position of the centre of gravity changes depending upon the ______.
3. The sum of all the vertical and horizontal forces acting on the body must be ______.
4. Centre of gravity is the average location of an object’s ______.

                                       OR

  d. When the sum of force acting upon the object and sum of the movement acting upon the body is both equal to zero then the body is said to be in ______.

Answer 1

1. The nearer the Center of Gravity to the Center of the base of support the more will be the stability.
2. The position of the centre of gravity changes depending upon the position of the intersection of force. 
3. The sum of all the vertical and horizontal forces acting on the body must be zero.
4. Centre of gravity is the average location of an object’s weight.

                                    OR

d. When the sum of force acting upon the object and sum of the movement acting upon the body is both equal to zero then the body is said to be in equilibrium.
