Name Date: Student Exploration: Free-Fall Laboratory Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts in the orange boxes. Vocabulary: acceleration, air resistance, free fall, instantaneous velocity, terminal velocity, velocity, vacuum Prior Knowledge Questions (Do these BEFORE using the Gizmo.)1.Suppose you dropped a feather and a hammer at the same time. Which object would hit the ground first? The hammer because it has much more mass then the feather2.Imagine repeating the experiment in an airless tube, or vacuum. Would this change the result? If so, how? Yes, since there is no air resistance in the vacuum, they would fall at the same speed Gizmo Warm-up The Free-Fall Laboratory Gizmo allows you to measure the motion of an object in free fall. On the DESCRIPTION tab, check that the Shuttlecock is selected, the Initial height is 3 meters, and the Atmosphere is Air
