| Forces and Motion (Chapters 2 and 3) Newton's First Law of Inertia Inertia is Latin for "idle" so we call it the Law of Laziness - objects like to keep doing whatever they are doing 1) Read section 3.1 and 3.2 and review the First Law of Motion and Unbalanced Forces 2) What happens when you don't wear a seatbelt? 3) What is the effect of gravity and air friction on falling objects? A. Check out what happens when you fire a cannonball off a mountain at Newton's Cannon B. Effect of Air Friction on a ball - try it with air friction and then turn off the air resistance Newton's Second Law Force = mass x acceleration 1) Review Newton's Second Law at BBC Bitesize Physics 2) Review balanaced and unbalanced forces at BBC Bitesize Physics. 3) Mass and Gravity - review the difference between mass and weight, do the practice test Newton's Third Law 1) Review Newton's Law of Action-Reaction and do the practice questions. Review Forces and Newton's 3 Laws of Motion 1) Practice vocabulary with a matching game 2) Take a practice quiz on Forces and 3 Laws. Check your answers online. Show me your score Done?
