Concept explainers
A friend says that astronauts in orbit are weightless because they're beyond the pull of Earth’s gravity. Correct your friend’s ignorance.
To correct: One’s ignorance that astronauts in orbit are weightless because they are beyond the pull of Earth’s gravity.
Explanation of Solution
Introduction:
The force of gravity is the attractive force between any two bodies that are having mass. This force is always attractive because it continuously attempts to pull the bodies together and never tries to push them away from each other. Law of universal gravitation states that gravitational force
No, astronauts are in free fall condition because of that they feel weightless in orbit. They are in orbit only because of the Earth’s gravitational force of attraction on them. If there is no pull of Earth’s gravity on astronauts they would fly off in a straight-line in to the space.
