Forces this week in Physical Science

This week in Physical Science we will be continuing our discussion of forces, including Newton’s Laws applications and free-body diagrams. A good understanding of forces is critical in the fields of physics and engineering, and consequently we will spend a significant amount of class time discussing the concept.

Owing to a delay in the delivery of critical components necessary for our velocity lab, it had to be delayed from last week till tomorrow; students will be analyzing the motion of and forces acting on battery operated motion buggies.

For 5 points of extra credit, students can answer the following question (due tomorrow, April 18th):

Mr. Willco has a mass of about 67 kg. What is the gravitational force (in N) acting on him if he were standing on the surface of Mars?
