Student exploration free-fall laboratory

Check that Air is selected. Click Play. The objects are now in free fall, pulled to Earth by the force of gravity. Did the objects fall at the same rate?

Extend Your Gizmo Pass. Investigate the motion of an object as it falls to the ground. A variety of objects can be compared, and their motion can be observed in a vacuum, in normal air, and in denser air. The position, velocity, and acceleration are measured over time, and the forces on the object can be displayed. Using the manual settings, the mass, radius, height, and initial velocity of the object can be adjusted, as can the air density and wind.

Vocabulary: acceleration, air resistance, free fall, instantaneous velocity, terminal velocity, velocity, vacuum. The box labeled h m should be checked, displaying a graph of height vs. What does this graph show? Velocity is the speed and direction of the object. Velocity is also referred to as instantaneous velocity. Because the shuttlecock is falling downward, its velocity is negative. Acceleration is the rate at which the velocity changes over time. Observe: Drop each item through Air from a height of 3 meters. Record how long it takes to fall below. For the tennis ball, try to click Pause when it hits the ground. Shuttlecock Cotton ball Tennis ball Rock Pebble. Predict: A vacuum has no air. How do you think the results will change if the objects fall through a vacuum?

Rating: 3 out of 5 stars. Ping Pong ball B.
