Answer 1

1) What force(s) are acting on the ball as it travels upward?
- the downward force of gravity

2) If you threw a ball in a gravity-free environment it would —
- continue to move in the same direction at the same speed

3) Gravitational force is required for one object to orbit another.
- True

4) Which pair will experience the greatest gravitational force?
- 2 large objects close together

5) Why do people in the space station experience weightlessness?
- They are falling together

6) Without gravity, objects would be weightless.
- True

7) Which scientist proposed his own idea of gravity after Isaac Newton?
- Albert Einstein
