“Weight and inertia are proportional, and on the earth’s surface are often taken to be numerically equal, which causes a certain confusion to the student. On Mars, weights would be different but the amount of force needed to overcome inertia would be the same.”
What does it mean?
The statement seems confusing!
If we try to throw a ball up on Mars then it would require less force than on Earth because the resisting force of gravity is less. Weight is less!
