Question

Force has the same unit as?

Answer 1

Answer:

Force : N or kgms−2

Displacement : m

Force * Displacement : J or kgm2s−2

Power : W or kgm2s−3

Energy : J or kgm2s−2

Acceleration : ms−2

Momentum : kgms−1

By comparing the base units, we can see that energy and force * displacement in direction of force have the same units (J or kgm2s−2 )
