1. Gravity is a c͟o͟n͟t͟a͟c͟t͟ f͟o͟r͟c͟e͟ that acts between two separate objects.
2. Gravity is the force exerted by the Earth which is equivalent to the m͟a͟s͟s͟ of an object
3. Gravity on the Moon is l͟e͟s͟s͟ than the gravity on the Earth.
4. Friction, unlike gravity, is a n͟o͟n͟c͟o͟n͟t͟a͟c͟t͟ f͟o͟r͟c͟e͟
5. f͟r͟i͟c͟t͟i͟o͟n͟ keeps objects from sliding off surfaces.
6. The principle of gravity was discovered by S͟i͟r͟ i͟s͟a͟a͟c͟ n͟e͟w͟t͟o͟n͟
7. Friction is the force that opposes the p͟u͟s͟h͟ of gravity on objects.
8 The l͟e͟s͟s͟e͟r͟ the mass of an object, the greater the pull of gravity on it.
9. g͟r͟a͟v͟i͟t͟y͟ keeps anything from going up.
10. Gravitational pull between objects i͟n͟c͟r͟e͟a͟s͟e͟s͟ as the distance between them decreases.​
