Student exploration free-fall laboratory

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 student exploration free-fall laboratory air. The position, velocity, and acceleration are measured over time, and the forces on the object can be displayed.

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? Which object fell faster? The watermelon fell faster.

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.

The acceleration of all objects is 9. Exploration Sheet Answer Key. Drop the ping pong ball from the lowest 5 meter platform, then the next platform 10 m and so on.

Home Find Gizmos Lesson Info. 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.
