Measuring gravity using the ball-drop method Measure acceleration of gravity using the period of a pendulum.Understand the limitations of this method.Measure the acceleration of gravity using the ball-drop method.Explain how the acceleration of gravity gives a planet’s mass.The values of aĪ gt 2, the acceleration in centimeters/(6-Īcceleration in cm/sec 2. Successive 6-dot interval and hence is an The increase in the distance fallen in each That the increase in distance fallen is aĬonstant. The weight falls farther during each timeĮach of these distances, AB, BC, CD. Interval, you must subtract each equation Substituting 2t for t and simplifying) by In covering the distance from A to C, theĢt, and fell a distance d 2 described (on Theĭistance d 1, is described by the equation
The record, which ought to be at least 2.5 meters long.Īt A, the tape already had a speed of v o.Ī time t, a distance we shall call d 1. Continue marking every sixth dot with a letter throughout the length of Count 5 intervals between dots, and mark the end of the fifth space Label with an A one of the first dots that is clearly formed near the beginning of

Made to yield a series of dots on the tape without seriously retarding its fall. Mark several feet of tape with a series as the tape is accelerated After a few practice runs, you will become expert enough to Small mass affects the timer frequency by much less than 1 The timer has a frequency of 60 vibrations/sec. Time intervals on the tape pulled down after the weight. When the suspended weight is allowed to fall, a 110-v timer will mark equal Since one of the group must climb a ladder in order to place the tape in the timer and do the drop. Physics, by permission of Science Electronics, Inc., Nashua, New Hampshire.Ī 110-v timer is set up about 2.5m above the laboratory floor. With careful handling, this can support at least a kilogram weight. Reinforce the tape by doubling a strip of masking tape over one end and punch a hole in the reinforcement one centimeter from the end. See experiment results.) The weight is suspended fromĪbout 3 meters of paper tape. (The drag on the paper strip has too great anĮffect on the fall of lighter weights.
The falling object is an ordinary laboratory hooked weight of at Resistance to become important, and since other sources of frictionĪre very small, the acceleration of the falling weight is very nearly Since the distance and hence the speed of fall is too small for air In this experiment you measure the acceleration of a falling object.

Performing this experiment, you will become more familiar with the effects of gravity-you find theĪcceleration of bodies in free fall yourself and you will learn more Questions about gravity have yet to be answered satisfactorily.
Gravity always remained the same? These and many other The gravitational force transmitted? Has the acceleration due to How can the earth make a body at a distance fall toward it? How is Bodies near the earth fall toward it with a certainĪcceleration due to the gravitational "attraction" of the earth. Meaning to the idea of gravity by seeking out the laws according to After all, we know theĪnswer: It's gravity that makes things fall.īut just what is gravity? Newton tried to give operational Natural places sounds strange to us today. EXPERIMENT: MEASURING THE ACCELERATION OF GRAVITY: a gĪristotle's idea that falling bodies on earth are seeking out their
