Boat Crossing A River
Emily (Avril and Laura)
This experiment was designed to find the constant velocity of the river relative to shore using
the velocity of the car relative to the shore and the velocity of the car relative to the river.
Activity: Ball and Car Race
Partners: Michelle Li, Grace Zhang
1. Variables: Velocity of the car, velocity of the ball, distance of the car, distance of the ball, time
(shared by the ball and the car).
2. We will place the ramp on an inclined sur
