If the rockets of a spaceship in outer space (far from all gravity) suddenly lose power and go off, the spaceship will gradually slow to a stop. true or false?

false

Explanation:

Objects in space also follow the laws of physics, hence the spaceship which follows newtons first law of motion (an object in rest stays at rest and an object in motion stays in motion unless being acted upon by an external force) which means it would be having inertia will not stop after loosing power and going off unless another force stops it, and also there is no air or atmosphere in space to act as resistance to the space ship.

think about the oscillation of the toy shown in the video. when the toy is at the highest point of its motion, its velocity is zero and its acceleration is negative.

the part of the wave he is travelling on is the crest
