Question

An astronaut of mass m in a spacecraft experiences a gravitational force F=mg when stationary on the launchpad.

What is the gravitational force on the astronaut when the spacecraft is launched vertically upward with an acceleration 0.2g.


A)1.2g B)mg C)0.8 mg D)0

Answer 1

gravitational force is the attraction force of earth on an object which is near the surface of earth

It will not depend on the velocity or acceleration of earth

So it will not change while an object is stationary or it is moving with some acceleration

So here we will say that force will remain the same

$F = mg$
