Miss Zelle's Chapter 15 Lesson 2 Quiz Friday

In science this week we learned about Chapter 15 Lesson 2, What is Acceleration.  We are going to be taking our quiz on Friday this week.  Your child should study the following:
  • Velocity: is when you tell both the speed and direction.  Ex: 30 mph, north
  • Acceleration: is any change in the speed or direction of an object's motion.  Acceleration is any change in velocity.  Ex: speeding up, slowing down, and turning
  • Force- is a push and pull of all kinds.  Force changes motion, which in turn causes acceleration. 
  • Inertia- is the property of matter that keeps matter moving in a straight line, and keeps unmoving matter at rest.  Ex: a magician pulling a tablecloth from underneath dishes.
