Today's Lateral Thinking question:

Now Playing During Lunch

Speed, Velocity, and Acceleration

Speed and velocity in their simplest terms. Watched

Today's Class:

We will continue with our notes over the chapter. Students will share their posters and I will supplement with lecture. In this unit you will need the conversion factor that 1 meter per second (m/s) is equal to 2.2 miles per hour (mph) or 1m/s=2.2mph. This can be written 2 ways depending on if you are trying to covert from mph to m/s or m/s to mph. 1m/s over 2.2mph OR 2.2mph over 1m/s. Take this example: a car is traveling at 26 mph and you want to know that speed in m/s. We need to use the conversion factor that allows us to cancel out mph and be left with m/s in the answer. Take 26mph over 1 / 1m/s over 2.2mph=  11.8 m/s
Today we will learn to use the Acceleration equation.
Ticket out the door- complete one of the speed and velocity problems from the overhead using the 5 step method.
