Question

Think of the term that fits into or defines the given statement and fill in the given boxes with the correct spellings of that term.

Work done is ___________ for a body falling freely under _________.

• A. positive
• B. gravity

Answer 1

1. When a body is freely falling, due to the force of gravity, the force and the displacement are in the same direction.
2. $$\begin{gathered} Workdone=Force\times Displacement\times Anglebetweenthem \\ W=FS\cos \theta \\ forW=+ve=\cos \theta =1=\cos 0 \\ i.e.insamedirection \end{gathered}$$

Hence, the work done is positive for a body falling freely under gravity.
