Question

how can velocity be zero or negative​

Answer 1

Answer:

When I release the spring from rest, the force due to gravity and the force due to spring(restoring force) are the two forces acting on the block.

According to me,when:

magnitude of Force due to gravity> magnitude of Restoring force, then the velocity of the body increases.

magnitude of Force due to gravity=magnitude of Restoring force, then the acceleration of the body is zero, and the body has maximum constant velocity.

Answer 2

Explanation:

Hey mate......

Velocity is displacement upon time and since displacement is a vector quantity (changes with direction), velocity is also a vector quantity. ... velocity is vector quantity, hence it can be negative (direction wise from mean position). zero velocity means magnitude of the velocity is zero.
