Cards Term Define speed. Definition The distance an object travels in a certain amount of time Term How do you calculate speed? Definition speed=distance/time Term What is velocity? Definition The speed and direction of an objects motion Term What is velocity? Definition The speed and direction of an objects motion Term Define Frame of Reference. Definition A place or object that you assume is fixed. Term What is the difference between speed and velocity? Definition Speed is the distance and objct travels while velocity is the speed and direction. Term which one is more accurate, speed or velocity? Definition velocity Term What is constant speed? Definition when an object doesnt change its speed Term What is the difference between average speed and constant speed? Definition constant speed stays the same while average speed is always changing Term What is the difference between average speed and constant speed? Definition constant speed stays the same while average speed is always changing Term What is the difference between average speed and constant speed? Definition constant speed stays the same while average speed is always changing Term What is acceleration? Definition the rate at which velosity changes Term How do you calculate acceleration? Definition acceleration=final velocity-starting velocity/time Term What does positive acceleration show? Definition an increase in speed Term What does negative acceleration show? Definition a decrease in speed Term What is deceleration? Definition decreasing of speed Term Acceleration caused by motion in a circle is called what? Definition centripetal acceleration Term Acceleration caused by motion in a circle is called what? Definition centripetal acceleration Term What is energy? Definition The ability to work Term What are 3 examples of energy? Definition Kinetic, potential, conservation of energy Term How do you calculate kinetic energy? Definition K.E.=mass x velocity(squared)/2 Term Can energy be destroyed? Definition No Term What does G.P.E. stand for? Definition Gravitational Potential Energy Term Define kinetic energy. Definition energy of motion Term What are 3 types of acceleration? Definition Positive, negative, and change in direction
