Question | Answer |
---|---|
Force | "A push or a pull" (Houghton Mifflin Harcourt, 2015, p.30) . |
Inertia | "The tendency of an object to resist a change in motion unless an outside force acts on the object" (Houghton Mifflin Harcourt, 2015, p. R51). |
Motion | "An object's change in position relative to a reference point" (Houghton Mifflin Harcourt, 2015, p. R52). |
Balanced Force | When forces are balanced on the object at rest it will not move. An object already moving will continue to move steadily (Houghton Mifflin Harcourt, 2015). |
Unbalanced Force | When forces cause the object to change its speed and/or direction (Houghton Mifflin Harcourt, 2015). |
Force Pairs | "Whenever one objects exerts a force on a second object, the second object exerts an equal and opposite force on the first" (Houghton Mifflin Harcourt, 2015, p.38). |
Newton's First Law of Motion | "Objects at rest will stay at rest and objects in motion will stay in motion unless acted upon by an outside force" (Houghton Mifflin Harcourt, 2015, p. 34). |
Newton's Second Law of Motion | The more mass an object has, the more force will be required to accelerate it (Houghton Mifflin Harcourt, 2015). |
Newton's Third Law of Motion | "Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first" (Houghton Mifflin Harcourt, 2015, p. 28). |
Acceleration | "The rate at which velocity changes over time" (Houghton Mifflin Harcourt, 2015, p. R50). |
