A body is moving in deep space substantially away from others influences of gravitational force ( just assume).
Suddenly, a big planet appears in It's vicinity. As per relativity it's not some force issuing forth from the planet that attracts the body towards itself. The body just keeps on moving as before, only the space is curved this time.So, it starts to move towards the planet. OK till now, I suppose.
My question is, 'why does the body accelerate/increase its speed.Why doesn't it keep moving at the same speed as before?
Or, do the people on the planet only SEE it to be accelerating towards the planet, as it is moving closer to the planet with time? Is the speed of the body same as before?
I hope there is nothing objectionable with this post
