Gravity A Force of Attraction http://www.brainpop.com/science/motionsforcesandtime/gravity/

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. http://www.bing.com/videos/search?q=minute+physics+gravity&mid=C26CA968F2FF95A78B2BC26CA968F2FF95A78B2B&view=detail&FORM=VIRE2&adlt=strict

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

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.

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

The Core of an Idea Sir Isaac Newton

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)

Gravity & Mass

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.
