Per NCERT Class 9 Science, WORK is done by a constant force F when an object undergoes a displacement s in the direction of the force. What is the formula for work done W?
AW = F + s
BW = F / s
CW = F − s
DW = F × s
Answer & Solution
Correct answer: D. W = F × s
Per NCERT Eq. 7.2, W = F × s (force times displacement in the direction of force). The other formulas misstate.
