1. Which of the following best describes the force of gravity?
A force that pushes objects apart.
A force that attracts objects with mass towards each other.
A force that only affects objects in space.
A force that is only present on Earth.
2. What two factors primarily affect the strength of the gravitational force between two objects?
Color and shape
Temperature and pressure
Mass and distance
Speed and direction
3. The more an object has, the stronger its gravitational pull.
4. As the distance between two objects , the gravitational force between them decreases.
5. Gravity is only present on Earth and the Moon.
True
False
6. The force of gravity keeps planets in orbit around the Sun.
True
False
7. Imagine you are on the Moon. Would your mass change? Would your weight change? Explain your reasoning.
8. Describe how gravity influences the tides on Earth.
This image reminds us of Isaac Newton and the legendary apple that inspired his thoughts on gravity. While the story might be a simplification, it highlights the fundamental concept of objects being pulled towards the Earth.
