No need to travel ... the lesson will come to you! A well-designed lesson begins by describing the rate of change of a distance-time graph highlighting areas of constant, increasing, and decreasing speed. The video instructor then shows...

Don't fall for these common misconceptions about falling objects! Using two sports balls with different masses, the interviewer demonstrates in a brief video the forces at work. Participants marvel as a much-heavier medicine ball lands...

The formula for uniform motion, meaning something is moving at a constant speed, is d=rt. This involves distance, rate, and time. If the word problem gives two of any of these values, the third unknown value can be found.
