OBJ: Given lab SWBAT determine the variables (mass?, size?, ramp height?) that effect the distance a ball is able to move a stationary cup with 70% accuracy. DN: Hand-in SVQ2 Quiz scantron Review Procedures, Graphing ACT: Complete Procedures, Graphing and all Questions HW: Complete Ball and Ramp Lab write-up (lab due Tomorrow; BRL lab quiz Tuesday); Energy Exam, Tuesday, January 6; Return W & C Textbooks, Dec 18,19.

2. Measure from the BACK of the cup.
Procedure A
Books
Procedure B
Measure from the BACK of the cup.

3. To answer the questions, you could say:
Ball traveled farther; less Ball moved faster; slower Ball weighs more; less The cup moved farther; less Kinetic energy increases; decreases Potential energy increases; decreases

4. Remember P.E.= weight (mass) x height K.E. = ½ mass x velocity²
max. potential energy
kinetic energy = 0
mass
Work done
decreasing potential energy; increasing
kinetic energy
mass
height
potential energy = 0
max. kinetic energy
Work = Force x Distance

5. Remove with smart board off
C. Wisnowski has ramps and metal balls
