Question

Write the three equations of motion for a freely falling body also write the meaning of the symbols

Answer 1

Answer: For a freely falling body,

1. v = u ± gt

2. h = ut ± 1/2 gt²

3. v²- u² = 2gh

Explanation:v is final velocity of the body, u is initial velocity of the body, g is acceleration due to gravity, t is the total time taken, h is height from which the body is dropped. The positive or negative signs are given to the values with reference to their positions and may vary according to the situation. Value for u is generally taken as zero for freely falling body.

Hope this helps!
