Transcript Ball and Ramp Lab Day 2 - Hicksville Public Schools / Homepage

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.
Procedure A
Books
Procedure B
Measure from the BACK of the cup.
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
Remember
P.E.= weight (mass) x height
mass
height
K.E. = ½ mass x velocity²
max. potential energy
kinetic energy = 0
decreasing potential
energy; increasing
kinetic energy
mass
potential energy = 0
max. kinetic energy
Work = Force x Distance
