2. Symbol: G

3. Force: Earth

2. Explore what factors are related to the size of gravity

1. Conjecture:

What is the relationship between the gravity of an object and _____?

Explore the relationship between the gravity on an object and its mass.

2. Design experiments

Class summary

1. Gravity: There is a mutual attraction force between any two objects in the universe, from as large as celestial bodies to as small as dust.

2. Gravity: the force exerted on an object due to the attraction of the earth, symbol G

3. The magnitude of gravity: The gravity experienced by an object is proportional to the mass of the object.

4. Direction of gravity: vertically downward (pointing to the center of the earth)

5. The point of action of gravity: center of gravity
