Ryan Cates University of South Florida Big Idea 11: Energy Transfer and Transformation Force and Motion: Part i
Vocabulary Review • Conductivity • Insulator • Magnets have north and south ______? • Name 3 types of potential energy • Definition: The energy of motion. • Mass
Forces and changes in motion*VOCABULARY* • Force – A push or pull on an object. • Some forces act through physical contact while others act from a distance. • Weight – The force (pull) that gravity puts on mass. Calculated by mass* the gravity constant. • Gravity – A force of attraction the earth has terrestrial bodies.
Weight is different on other planets • Weight = Mass x Gravitational Constant • Gravitational Constant = 32.2 ft/s2 http://www.exploratorium.edu/ronh/weight/
Newton’s first law • An object that is in motion will stay in motion or an object at rest will stay at rest until acted upon by another force.
