Ball on Floor Lab - Day 2

Ball on Floor Lab - Day 2

Learning Objective: I can conduct an experiment that is a mathematical model for the relationship between distance, speed, & time.

Wild Guess Question: How far will the ball travel in 6 seconds? ____meters

Research Question: What is the relationship between the distance a ball rolls and the time it rolls?

Hypothesis: I think as the time increases, the distance traveled will _________ in a ________ pattern. 

IV: Distance
DV: Time

Controls: angle of ramp, mass of ball, ?

Procedure: Start timing at 2nd tape! Do 3 trials for each distance. 

Data Table:
x=time in seconds (avg) 
y=distance in meters
Trial 1, 2, 3
Uncertainty of x values (range/2)


Graph in DESMOS

Equation: D=___T  (Distance = 'a' value x Time)
a = constant velocity; a = slope

Conclusion: After investigating the relationship between _________ and __________, I found a __________ relationship. The equation of the line is ______________, which is a mathematical model of the relationship between __________ and __________. Using this model, I predict ____________________.
