Motion Of Body Under Gravity - Practice Questions & MCQ

The force of attraction of the earth on anybody is called the force of gravity. Acceleration produced on the body by the force of gravity is called acceleration due to gravity. It is represented by the symbol ‘g’.

Sign convention:

• Upward direction and right direction is taken as positive
• Downward direction and left direction is taken as negative

There are three cases basically in this - 

             1) If a body dropped from some height (initial velocity zero)

                      u = 0 

                      a = g

            2) If a body is projected vertically downward with some initial velocity

            3) If a body is projected vertically upward.
