LessonCruisin' the Mall and the MBL
Learning to search, cut and paste from the Mall. Introduction to MBL activities.
Kinematics with MBL.
-body motion
-constant velocity
-constant acceleration
Keywords: dimensional analysis, units, kinematics, displacement, velocity, acceleration,
translational motion, rectilinear motion
Week of January 19, 1998
Lesson 21D Dynamics (low friction w/ visible applied forces)
-define constant Fapp
-observe a( Fapp
-define F scale
-observe more stuff ( < a
-define static mass scale
-observe a((1/m)
-observe Fnet = (Fapp = ma
-observe First Law
i.e. if (Fapp = 0, then v=const.
Keywords: forces, mass, acceleration
Week of January 26, 1998
Lesson 31D Dynamics (invisible Forces)
-observe friction w/ visible drag as a "passive force"
-postulate friction as force
-observe vertical fall
-postulate constant gravitational force
-observe effects of strings and surfaces
-postulate Newton's third law to explain a= 0 cases
-postulate T and N as passive forces
Keywords: forces, mass, acceleration, friction, gravity, tension
Week of February 2, 1998
Lesson 42D Dynamics
-observe vector combination of forces
-discover rules for freebody diagrams and 2D problem solving
-apply Newton's laws to projectile, circular and inclined plane motion
Keywords: free body diagrams, Newton's Laws, planar motion, projectile motion, circular
motion, centripetal force
Thursday of the 4th Week:First Hour Exam - February 5th80 points
The exam will use the complete class period and will be part print
and part electronic.
Week of February 9, 1998
Lesson 5Momentum Conservation and Collisions
-Observe impulses and p-change
-Derive F[!]t=[!]p theorem from Newton's 2nd Law
-Use MBL to verify F[!]t=[!]p theorem experimentally
-predict interaction forces during collisions if m1>m1 or v1>v2
-Use MBL to observe interaction forces(F12 =-F21 always)
-Combine dynamic Third Law with F[!]t=[!]p to get 1D p-conservation
-Center-of-mass, 1D collisions, 2D collisions, and particle systems
