Part 2: Thinking Time! (Sample Answers)
- A force is a push or a pull. Pushing a toy car is a push. Pulling a wagon is a pull.
- Gravity is a force that pulls objects toward each other. Earth's gravity pulls everything down to the ground.
- The ball comes back down because of Earth's gravity pulling on it.
- Mass is how much stuff is in an object, and it never changes. Weight is how hard gravity pulls on that object, so it can change if you go to another planet.
- You use a pushing force with your feet against the ground.
- It would be easier to jump high on the Moon because the Moon's gravity is much weaker than Earth's, so it doesn't pull you down as hard.
- A force can make an object start moving, stop moving, change direction, or change shape. (Any two are correct).
- A heavy school bag has more mass (more books and stuff inside), so the force of gravity pulls down on it more, making it feel heavier.
- It has a strong pull of gravity. (Like the Sun or Jupiter).
- (Answers will vary). Example: I used a push force to push my chair in. I used a pull force to open the refrigerator door.
