Dr. Forrester talks about Columbus’s second voyage to the New World with seventeen ships and a thousand men.

Dr. Forrester teaches about Newton’s Second Law of Motion.

Mr. Addit reviews telling time by the hour and half-hour. He then explains how to tell time by the minute.

Mr. Addit explains the measurement of time: seconds, minutes, hours, days, and so on. He then compares an analog clock to a digital clock and how each clock tells the time of day.

Miss Palomine sorts through old photographs and talks about the passage of time. This leads to a description of time and how clocks are used to tell time.

Miss Palomine references day 11’s lesson of order of events to instruct the student to learn the order of numbers: 1, 2, 3. She teaches the student the terms, “first,” “second” and “third.”

This problem is about using Newton's 2nd Law to determine the acceleration of a block being pulled at an angle on a level surface.

This problem is about using the derivative and Netwon's 2nd Law to determine the time at which the net force on an object is zero.

This problem is about what happens to the center of mass of two people standing on a frictionless surface and they push away from one another.

This problem is about using Newton's 2nd Law to determine the velocity of two identical stars in a fixed orbit around their mutual center of mass.
