Question : Why is weightlessness experienced while orbiting the Earth in spaceships?
Option 1: Inertia
Option 2: Acceleration
Option 3: Zero gravity
Option 4: Orbital motion
Correct Answer: Zero gravity
Solution : The correct option is Zero gravity .
When there is no gravity, it is referred to as zero gravity. The combination of inertia, acceleration, and free fall causes the experience of weightlessness. In other words, the astronauts are not weightless; rather, they are feeling as though they are since they are falling towards the Earth at the same velocity as their ship.
