Question

if an object is moving ther must be a non zero force acting on it state whether true or false and justify ur answer briefly.

Answer 1

This is statement is false.
If object is moving, it can have uniform velocity or non uniform velocity.
If object is moving with uniform velocity then acceleration is zero hence force acting on the particle is zero.

If object is moving with non uniform velocity then object have some acceleration, so there is force which is acting on the particle.
