Look back at your definition of the word robot. Be prepared to share the examples of types of work that robots can do.
What is the science behind a spacecraft launch? • Force- Push or pull • Gravity- Attraction between any 2 objects Earth’s surface resists the downward force and keeps an object still
Newton’s First Law of Motion • An object at rest tends to stay at rest (inertia) unless acted on by a force. Example: pulling a piece of paper from under a science book versus pulling a piece of paper from under a staple
Newton’s Second Law of Motion • Force=mass x acceleration (F= m x a) Example: slide a crate across the floor, what happens to the equation when more mass is added? What happens to the equation when less mass is used?
Newton’s Third Law of Motion • For every action, there is an equal and opposite reaction Example: What is the action of the rocket taking off? What is the reaction?
Kinetic Energy • ENERGY OF MOTION
Potential Energy • STORED ENERGY • Gravitational potential energy Example: a golf ball setting on the edge of the table • Chemical potential energy Example: a carrot or banana
