 Neglecting air resistance, all objects fall at a rate of 9.8 m/s 2 due to gravity  Because objects fall in a downward direction, we’ll call their acceleration.

Rotocopter Lab ~I can calculate speed.

Question What is the effect of wing size on the falling speed of a rotocopter?

Hypothesis ~If, then because statement.

Experiment Make the rotocopter following the direction at your table.

Data Wing Size and Speed Height (cm) Time (s) Average of Time Speed (cm/s) Distance ÷ Time Trial 1 Trial 2 Trial 3 Regular Wings 200 cm Medium Wings Shorter Wings

Directions Stand on the table and measure the distance you are dropping the rotocopter to the floor. Drop the rotocopter from that distance and record the time it takes to hit the ground. Record the data. Fold the arms to make it shorter. Then drop from the same distance and record the time it takes to hit the ground. Fold the arms to make it the shortest.Then drop from the same distance and record the time it takes to hit the ground.

Complete the data Calculate the speed of each rotocopter. Show ALL your work, units, and formulas!!!

Finished?? Write your conclusion!!
