Newton's Laws

Study Guide

What is Newton's First Law of Motion? An object in rest will stay at rest, a object in motion will stay in motion, unless acted upon an unbalanced force.
What is inertia? Resistance to a change in motion, and an object with more mass will have more inertia.
What is Newton's Second Law of Motion? Acceleration is produced when unbalanced force act on a mass.
What is acceleration? Is a change in speed OR direction of motion.
What causes acceleration? An unbalanced force.
Why does an object eventually stop moving? Because of friction, without friction the object will continue to move unless there is an object with a bigger mass in front of it.
Why would an roller coaster need to have a lap bar or shoulder bar. Because according to Newton's First Law an object in rest will stay in rest, an object in motion will stay in motion, unless acted upon a force.
What is Newton's Third Law of Motion? For every action, there is an equal but opposite reaction.
What causes an object to move. Gravity and friction.
