Question

2. When a body moves in a direction
perpendicular to the direction of the force, no
work is done. Why?​

Answer 1

since perpendicular forces do not change the magnitude of velocity (only their direction), the perpendicular force should not enter into the equation of work (since it does not contribute to the energy change).

Answer 2

Answer:

Hyyy

Explanation:

For (1), since perpendicular forces do not change the magnitude of velocity (only their direction), the perpendicular force should not enter into the equation of work (since it does not contribute to the energy change).
