Inertial vs Non Inertial Frames
Will a man in a lift in space accelerating up with an acceleration g feel any different from a man in a stationary lift on Earth?
He will feel lighter
He will feel no difference
He will feel heavier
A particle stays at rest as seen in a frame. We can conclude that
the frame is inertial
resultant force on the particle is zero
the frame is inertial if the resultant force on the particle is zero
The frame is non-inertial if there is a non-zero resultant force.
A particle is found to be at rest when seen from a frame S1 and moving with a constant velocity when seen from another frame S2. Mark out the possible options.
Both the frames are inertial.
Both the frames are non-inertial.
is inertial and is non-inertial.
is non-inertial and is inertial.
Rajat is sitting in an open cart that moves horizontally with an acceleration of 5 m/s2 rightwards. Rajat is unaware of his acceleration, and throws a ball up in the air. He attempts at drawing a Free Body Diagram of the ball assuming his frame to be inertial. Which of these would closely resemble his free body diagram of the ball (neglect air drag)?
