Question

Can there be displacement of an object in the absence of any force acting on it? What are
the energy transformations during lighting an electric bulb?

Answer 1

Answer:

Yes, there can be displacement of an object in the absence of any force acting on it. Since mass 'm' cannot be zero, therefore, when force F = 0, then acceleration 'a' = 0. ... An objects thrown at a certain angle to the ground moves in a curved path and falls back to the ground.
