Went around the room and asked what the students told their parents about yesterday's class.
Handed back RA 4.1 and went over it.
Newton's First Law - An object at rest will remain at rest and a moving object will continue moving in a straight line with constant speed unless acted on by an outside net force.
Showed the students that a mass of 1 kg weighs 10 N on Earth.
Mass is NOT the same as weight.
Weight = mass * acceleration of gravity = mg = gravitational force of Earth on object
Weight is a force measured in Newtons.
Normal force = force perpendicular to the surface = FN or N
Introduced free-body diagrams - a picture that shows ONLY the forces that act ON an object. Went over Free-Body Diagram worksheet.
Tomorrow we will do the Statics Lab.

Students worked sample problems on calculations for Rocket Lab 2.
Ball and Ramp Projectile Competition.
Went over what is required for Rocket Lab 2 write-up.
Students had a little time to work on their Rocket Lab 2 calculations.
If I can get the laptops, we will do an Excel Spreadsheet exercise tomorrow.
