Question

If the trajectory of a body is parabolic in one reference frame, can it be parabolic in another reference frame that moves at constant velocity with respect to the first reference frame? If the trajectory can be other than parabolic, what else can it be?

Answer 1

Hii dear,

# Answer-
1. May or may not be parabolic
2. straight line

# Explaination-
We'll take an example to explain this.
Suppose, an object is thrown out from a train moving with constant velocity.

a) For an observer on ground, path of the trajectory is parabolic.

b) For an observer from same train, path of trajectory will be straight line.

c) For an observer from another train with different constant velocity, path of trajectory will be parabolic.
Hope that helps you...

Answer 2

The  trajectory of path of an  object is based on  the observer .

For example :

If we consider that we throw a ball from a train which is moving with constant velocity, then

--- w.r.t observer the person in the train ---- the trajectory path of ball is straight line.

-- w.r.t observer on the platform or outside train , the path is parabolic
