Free fall acceleration due to gravity is a concept that is fundamental to the study of physics. It refers to the rate at which an object falls towards the Earth due to the force of gravity. In this lab report, we will explore the concept of free fall acceleration and how it can be measured using a simple experiment.

To begin, we need to understand the basic principles of free fall. According to Newton's law of motion, an object in free fall experiences a constant acceleration of 9.8 m/s^2, also known as the acceleration due to gravity. This means that the speed of an object in free fall increases by 9.8 m/s every second.

To measure the free fall acceleration of an object, we can set up a simple experiment using a timer and a ruler. First, we need to select an object to drop, such as a small ball or a pencil. Next, we need to set up a timer to measure the time it takes for the object to fall a certain distance. Finally, we can use a ruler to measure the distance the object falls.

To perform the experiment, we first need to mark a starting point and a stopping point on the ruler. We can then drop the object from the starting point and start the timer as it falls. When the object reaches the stopping point, we can stop the timer and record the time it took for the object to fall. We can then use this time, along with the distance the object fell, to calculate the free fall acceleration.

To calculate the free fall acceleration, we can use the equation: acceleration = distance / time^2. Using this equation, we can plug in the values for distance and time that we measured during the experiment to determine the free fall acceleration of the object.

Overall, the concept of free fall acceleration due to gravity is an important one in the study of physics. By performing a simple experiment, we can measure the free fall acceleration of an object and understand how it is affected by the force of gravity. This understanding can then be used to make predictions about the motion of objects in a variety of situations, such as the trajectory of a projectile or the landing of a parachute.

I measured and recorded the position from the start of the tape corresponding to each half time interval and then plotted a velocity-position graph using the velocities I recorded. Method II however, used a graph constructed from a small representative portion of the results. If you begin to accelerate from rest at a constant acceleration, your speed increases continuously. Procedure You will be measuring the acceleration due to gravity g in three ways. Another systematic error is that the ruler is not 100% accurate when measuring; it may be off by. A graph of this equation would yield a parabolic curve as shown in the example below.

Avoid numbers and symbols in the abstract. However, there are several factors that can impact this occurrence, including air resistance. Acceleration Due to Gravity Purpose : To determine how the velocity of two different masses released at the same time and height differs from the initial start of the fall. The relationship between the change in velocity and elapsed time was that the velocity increases constantly as the time increases therefore they were proportionate. The acceleration for the object in the velocity-time graph will be gravity 9. Gravity is therefore the force that pulls objects towards the center of the earth. The object started to fall as it was released from the magnet at time 0.

So this shows that the height or displacement is directly proportional to the time taken. The tape can then be analyzed and the velocity of the object determined by observing the change in the distance the object fell over time. The anticipated error was that the numbers would have been rounded and not completely accurate. This acceleration due to the force of gravity is always directed to the center of the earth and is independent of mass and shape of the object. This effect is demonstrated in figure 1.

Because of this, it is said that all objects free fall at the same rate of acceleration, regardless of their mass. Each opaque band on the Picket Fence blocks the Photogate beam and the time from one blockage to the next becomes increasingly shorter. You do not need a printout. Introduction Objects free fall due to the influence of gravity. Accelerations are always caused by forces. 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.

Picket Fence : Drop a Picket Fence a clear plastic strip with uniformly spaced opaque bands through a Photogate. In experimenting the Law the measurement of acceleration of gravity was used by measuring the distance a dropped ball travels for a specific amount of time.

The purpose of this experiment is to determine the amount of time that it will take for balls of different sizes to reach the ground when they are released from the same height. Therefore, objects of either same or different masses will reach the ground at the same time. The slope of the velocity time graph was accelerating 6. DO NOT TURN IN THIS LAB HANDOUT 2. Hypothesis It is hypothesized that the object that is dropped will endure gradual change acceleration in acceleration. Knowing the distance 1 between the leading edge of each opaque band, Capstone calculates the acceleration of the picket fence. We are trying to determine if the objects with heavier mass have a greater acceleration than those with a lighter mass.

The recording tape was threaded through the timer. This acceleration is commonly referred to as the acceleration due to gravity, and is given the symbol g. The clamp which initially holds the ball can be adjusted to varying heights above the metal pad on the floor Results: Comparison of Experimental Results:. Each ball was dropped from a height of five feet and the amount of time it took to reach the floor was measured using a stopwatch. Systematic errors may also have been associated with the instrument which may have affected the results. Since gravity was the only force acting on the object and it is constant we can use this relationship to experimentally determine the acceleration due to gravity by dividing the change in velocity by the time taken for that change to occur. A mass will be attached to the air-cart by a string and hung over pulley with the other end attached to an air-cart resting on a frictionless surface.

This is a measure of your precision. Free fall is when objects fall with only the force of gravity at work, without air resistance. Method I produced a higher percentage difference because more readings were taken which led to more variations and errors being included in the calculations. Preview text MOTION OF A BODY IN FREE FALL Oluseye Dare Gamoi Paisley Objective: To measure the acceleration of a falling object by observing the changes in the speed of that object. Plot a graph versus t2 plot t2 on the abscissa, i. This apparatus allows an object to be released from an elevated position, which is allowed to fall between two copper wires which will spark and leave marks on a waxed tape at a set time interval. Each trial was conducted at least three times.

Thus, velocity not only tells you how fast you are going, but also in what direction. If the velocity is increasing the mass free falls, then the acceleration of the object will increase as well. The larger the diameter of the ball, the longer it would take for the ball to fall, while the ball with the smallest diameter fell the quickest. Changing the time interval between sparks would not affect the slope of the graph, it may only cause the graph to be shifted to the left or to the right. How do you know? It is important to consider that despite the size of the ball, it fell at an acceleration of 9. Results were collected in an Excel file for further analysis.
