Answer:

Explanation:

we know that,

force = mass × acceleration

∴ since speed/velocity is constant, acceleration should be zero.

∴ f = m × 0

f = 0 N

∴ If we apply this to ,

work = force × displacement

we get ,

w = 0 × s

∴ we can say that the net work is zero.

and hence the answer is true!!!
