Welcome back from Spring Break! This week in 7th Grade Physical Science we will be starting our introduction to kinematics; the Motion, Forces, and Energy textbook will be very useful for this topic, and students should plan on having it with them whenever they plan on doing homework or studying. Kinematics is the study of objects in motion, and the name is derived from the Greek kinein, which means “to move”. What we today call kinematics has been studied since antiquity, primarily for its application to warfare (the arc of a siege engine’s projectile is well described by basic kinematics), but also for the design and operation of simple machines such as pulleys or levers.
You may notice your child asking to record your vehicle’s odometer reading on their way to school this week: they will be using this information to calculate their average speed on their way to school.
