In an experiment where you try to measure the acceleration due to gravity (g) by dropping an object from a certain distance into a sensor pad that measures the time of fall, what would be some of the experimental errors? I know that inaccurately measuring the height of the fall is one of them, but what would be other types of errors?
The equation needed to calculate g is 2h/t^2.
Homework Answers
The errors may be
An error due to air resistance in calculations affecting the time of fall
An error in measurements of the height
An error in stopwatch or measurement of time

A student developed an experiment to measure the acceleration of the gravity. In the experiment, two photogates were used to measure the time it takes the object to fall from rest (at the first photogate) and reach the lower gate. The distance between the two photogates was 50 cm and the recorded time was 319 ms (millisecond). Calculate the acceleration of gravity (magnitude).

A student developed an experiment to measure the gravitational acceleration. In this experiment, two photogates were used to measure the time it takes the object to fall from rest (at the first photogate) and reach the lower gate. The student recorded time (t) and the distance (y) between the two photogates as shown in the following table: t (s) y(m) 0.141 0.100 0.199 0.200 0.244 0.300 0.281 0.400 0.315 0.500 0.345 0.600 0.372 0.700 Use Excel to plot y versus...

The acceleration due to gravity, g, is constant at sea level on the Earth's surface. However, the acceleration decreases as an object moves away from the Earth's surface due to the increase in distance from the center of the Earth. Derive an expression for the acceleration due to gravity at a distance h above the surface of the Earth, 9h. Express the equation in terms of the radius R of the Earth, g, and h. 9A Suppose a 74.35 kg...

(1 point) The acceleration due to gravity, g, is given by 8= GM r2 where M is the mass of the Earth, r is the distance from the center of the Earth, and G is the uniform gravitational constant. (a) Suppose that we increase from our distance from the center of the Earth by a distance Ar = x. Use a linear approximation to find an approximation to the resulting change in g, as a fraction of the original acceleration:...

Note: Show this using kinematic equations,
please.
The acceleration due to gravity g near the surface of the Earth can be measured by projecting an object vertically upward and measuring the time that it takes to pass two given points in both directions. See the diagram below. Notice that the horizontal axis is time not position the path of the object is purely along a straight, vertical line. Show that if the time the body takes to pass a horizontal...
