How do objects move under the influence of gravity? Gravity and Motion How do objects move under the influence of gravity?

What is Gravity? Gravity is a force of attraction between objects due to their mass size. Mass depicts gravitational force

Gravity is a pulling force

Weight Weight is a measurement of the gravitational pull on an objects mass Weight in NOT constant Mass is constant

Your Weight on other planets When weight changes, does your mass? http://www.exploratorium.edu/ronh/weight/

What determines the force of gravity? Gravitational pull depends on distance and mass of an object

Keeping objects in orbit Free fall: when gravity is the only force acting on an object Orbit – when an object travels around another object in space. gravity and inertia working together you have an orbit

Gravity and Inertia

Objects fall at the same speed All mass sizes fall at the same speed. file:///C:/Users/bogat/Downloads/Falling_Objects.asf file:///C:/Users/bogat/Downloads/Mass_and_Weight.asf
