Question

opic: Projectile motion lab
After comparing your measured horizontal displacement(xm) with your refrecenced/calculated horizontal displacement(xref).
Discuss physical factors that may have affected your result but have been ignored. Also, discuss the how and why should such physical factors affect the result?.

concepts from two-dimensional kinematies to predict the impaut point of ban in motion, and compare the result with direct measurement. Introduction and Theory You have probably watched a ball roll ofra table and strike the floor, What determines where it will land? Could you predict where it will land? In this experiment, you will roll a ball down determine the bal s velocity a pair of You will use this information to predict where the ball will land on the floor, and compare with direct measurement.

Explanation / Answer

physical factors that may have affected your result -

1) Friction

2) Air drag

such physical factors affect the result -

1) Friction - Friction causes the horizontal range to be less than the ideal value .

2) Air Drag - Air drag causes the maximum height to be less than the ideal value .
