Question

A body is thrown upwards with velocity ‘u ’ and it attains a height h. Write the equation of motion for the body.

Answer 1

When an object is thrown upwards, the value of acceleration due to gravity (g) is negative.

Thus, equations of motion are:

(1) v = u - gt

(2) h = ut - \(\frac{1}{2}\) gt²

(3) v² = u² – 2gh
