Our plan was to drop an object from a reasonable height and use a ticker tape timer to measure the amount of time and distance travelled between each time. The weight of the object used would have to be heavy enough that it would not be affected by air resistance. For example, you shouldn’t use a piece of paper because due to the surface area and weight of the paper, the fall would be slower which would affect further calculations. However, if you used a weight which was heavy enough, the effect of air resistance would be minimal. For our experiment, we would use several things which would help us gather data so that our calculations would be nearest to the true value of g (acceleration due to gravity). One object which we used was a pulley system. We put a string through the pulley and attached the weight to the string. This supported the object by providing stability so it would fall straight down and not at an angle. If we were to drop it using our hands rather than a pulley, this could increase human error because we would not be able to drop it straight down.…
The goal behind this experiment was to estimate the distance a ball would travel after it falls a certain distance and bounces off a metal plate which has an angle of 45 degrees. To find this we had to take the basic equations for kinematics which are (1/2)at2=x and v=v0+at and combine them to make an equation that will help us solve for the distance the ball will travel after hitting the bounce plate. The equation came out to be R=g*(sqrt(2)/sqrt(g))*(sqrt(H)*sqrt(h)), as that g is acceleration of gravity, h is the height of bounce plate, and H is the height of where the ball will be dropped. After completing this experiment the result was that the standard deviation was +/- 2.3 cmfrom the average value of 26.5cm. This was used for each variable H was 20cm and h was 20cm. Also there 18 trials performed as well.…
The results that were observed from this lab helped prove what was hypothesized. As chart 1.4, 2.4 and 3.4 displayed the object dropped off of the 90 degree slope was the quickest to cross 200cm, had the highest velocity and the highest acceleration. This was because at 90 degrees the gravitational pull was…

2. Drop each ball from heights of 20 cm, 40 cm, 60 cm, 80 cm, and 100 cm. In all cases, record the bounce height in the data table below.…
A ball is thrown upward at time t = 0 s from the ground with an initial velocity of 4 m/s (~ 9 mph). Assume that g = 10 m/s2.…
During this laboratory exercise we attempted to show that the force of gravity has the same effect on all falling bodies near the earth. We intended to show this by dropping several objects in normal atmospheric conditions, and in a vacuum chamber. Our tests showed that while everyday experience may indicate that not all objects fall toward the earth at the same rate, they are submitted to the same force of gravity.…
Record your hypothesis here: If two objects fall at the same height then the object with the greatest mass will fall to the ground first.…
You will consider two variables—drop height and bounce height—to try to determine how drop height affects bounce height. You probably understand that a higher drop height will result in a higher bounce height, but in this experiment, your objective is to find out how one affects the other. For example, is the bounce height equal to 100% of the drop height or 50% of the drop height? Does the relationship change at…
Acceleration, however, is constantly 9.8 m/s²...the force of gravity does not change as the ball moves.…
Introduction Tonight we will measure the acceleration due to gravity again. This time however, we will collect more data and the analysis will be different. We will first fit the data using a second order polynomial. Recall for a mass falling from rest, that 1 (1.1) y a yt 2 2 Suppose a mass falls through n successively greater displacements, each time starting from rest. The displacements can be expressed a 2 y y t ; 1 n . (1.2) 2 Analyzing the Data Data for y is not linear in time t. We have two unique ways we can analyze the data. The first is to simply plot the data with vertical displacement on the y-axis and time on the x-axis and perform a 2nd order polynomial curve fit. We can then extract acceleration from the coefficient of the 2nd order term. The second method involves transforming the nonlinear data into a linear form by means of the logarithm from which we can extract acceleration. We are going to use both methods because it demonstrates the power of mathematics as a data analysis tool. Fitting the Data to a 2nd Order Polynomial Free-fall data is shown in figure 1 and has the form…
The acceleration of the 50 g rate weight was .10 greater than the weight of the 100 g weight; however, this is attributed to our sources of error. Therefore, we concluded that mass does not affect the acceleration due to…
The object of the experiment is to determine whether or not objects fall freely at the same rate and speed. Measure and calculate the time in which it takes random objects to hit the ground from a certain height and determine if the objects have the same rate of motion or not.…
The purpose of this Motion Lab was to find the acceleration of a steel marble going down a straight track six different times to figure out how an object’s mass affects acceleration. It doesn’t due to Newton’s second law of motion. There were six different accelerations for each trial and they are: 7.88 m/s squared, 6.78 m/s squared, 6.07 m/s squared, 5.57 m/s squared, 4.32 m/s squared, and 5.11 m/s squared. It’s possible to use any two points to figure out and calculate acceleration due to gravity. Sir Isaac Newton used the word “mass” as a synonym for “quantity of matter.” Today, we precisely define mass as a “measure of inertia of a body.” The more mass an object has the more difficult it is to change it’s state of motion, whether it is at rest or moving without net force acting on that body. In other words, without an outside force a body will remain still if still, if moving, keep moving in the same direction at a constant speed. The acceleration of an object is directly proportional to the net force acting on it and is inversely proportional to its mass. Also, the direction of the acceleration is in the direction of the net force acting on the object. Mathematically, this proportionally. In other words, if the mass is constant, the force and acceleration are directly proportional which is corresponding in two states. To calculate the acceleration of the ball at the time of impact, subract the ball’s initial speed (which is zero) from it’s final speed and divide by the time it took to hit the targer. In this lab, acceleration is independent of mass, but does depend on diameter (since the ball is rolling, not sliding or free-falling) the force imparted to the target ball had (about) the same acceleration, but different masses. One of the possible conditions of motion used is: Rest, from the steel marble starting at the top of the inclined track at 0 then rolled down, causing another…
