1. Gravity A Force of Attraction

2. The Effects of Gravity on Matter
Gravity – force of attraction between objects that is due to their masses.
Gravity is a result of mass
Pulling Force
All objects experience an attraction toward all other objects.

3. Team Work Make a poster Pick an activity that is affected by gravity
Explain through pictures why gravity is beneficial and harmful to that activity

4. The size of the Earth’s Gravitational Force
The earth’s large mass = large gravitational force
You must apply forces to overcome Earth’s gravitational force anytime there is a lift.

5. Newton and the study of Gravity
Why do objects fall toward earth?
What keeps the planets moving in the sky?

6. The Core of an Idea
Sir Isaac Newton

7. The Law of Universal Gravitation
Describes the relationship between gravitational force, mass, distance. ALL OBJECTS IN THE UNIVERSE ATTRACT EACHOTHER THROUGH GRAVITATIONAL FORCE. (the size of the force depends on the masses and distance of the objects)

9. Gravity & Mass

12. Weight as a measure of gravitational force & The difference between mass and weight
Weight (N) – a measure of the gravitational force on an object. Mass (kg) – the amount of matter in an object.

14. Gravity from Universe DVD Video Series

15. Tides and the moon
