Is it possible for a particle to describe a curved path if no force acts on it? Does your answer depend on the frame of reference chosen to view the particle?
Answers
Answer:
It is not possible for a particle to describe a curved path without involvement of force
Indeed, if the frame of reference represents a curved path, the answer depends on the frame of reference chosen to view the particle.
Explanation:
If there is no force acting on the particle, its direction cannot be changed. So, when zero force applied on it, then it is not yet possible for a particular particle to describe a curved path.
Every particle tends to remain in its linear motion state (motion in a straight line with same velocity) or in a resting state until an unbalanced external force applied on it. This is the first law of Newton. But why do I say it?
Okay, when you mean that you want to interrupt its motion in a straight line by saying "curved road," in other words you want to change its pace. You must therefore apply an external unbalanced force perpendicular to the tangent at a certain point on a curved line.
Indeed, if the frame of reference represents a curved path, the answer depends on the frame of reference chosen to view the particle.
