Picket Fence Free Fall
We say an object is in free fall when the only force acting on it is the Earth’s gravitational force. No other forces can be acting; in particular, air resistance must be either absent or so small as to be ignored. When the object in free fall is near the surface of the ear...
Purpose: To observe and measure the acceleration of gravity of a free falling body (picket fence) at sea level and to compare the measured acceleration with the accepted value of 9.8 m/s². To observe and measure the difference between dropping the picket fence right above the Photogate and 20 cm hi...
The purpose of the Picket Fence Free Fall Lab was to examine the acceleration of objects as they fall to earth. During free-fall the only force that should be acting upon the object is the earth’s gravitational pull (9.8 m/s/s), therefore the velocity of the object should always equal 9.8 m/s/s. I...
In this experiment we explored some basic concepts regarding the acceleration of Earth’s gravity (g) in order to develop further understanding about measurement and combining uncertainties. We then compared our measured value for g to the accepted value of...

Hypothesis: As slope increases, acceleration increases.
Introduction: Speed is the distance traveled per unit time, velocity at any given moment is the slope of the tangent line through any relevant point on the graph, acceleration is the rate at which an object changes its velocity, and instanta...

Lab #8: Newton’s Second Law and Acceleration Due to Gravity
To observe a few effects of constant force and varying mass, constant mass and varying force and varying both mass and force and relate them to Newton’s Second Law.
Theory and Background:...
Free fall and the acceleration due to gravity
Problem/Question: How do you measure the acceleration of a falling object?
Hypothesis: by measuring velocities of a falling ball then applying the data into equations numerous times, the results should approach to the acceleration.
Physics 211 Experiment 1: Free Fall - Determining the acceleration of gravity
Prior to Lab: Derive the numbered equations (Equations 1, 2 and 3) in the lab instructions using the definitions of velocity and acceleration (a=dv/dt and v=dy/dt).
Object: The object of this experiment is to determi...
Chapter 6 Newton’s Second Law of Motion-Force and Acceleration
The Big Idea: An object accelerates when a net force acts on it.
6.1 Force Causes Acceleration
• Unbalanced forces acting on an object cause the object to accelerate.
• The combination of foces acting on an obje...
The purpose of this experiment is to determine whether a change in mass affects the acceleration of the cart. The independent variable is the mass of the weight and the dependant variable is the acceleration. I do not think there is a control in the experiment because we do not know an...
The purpose of this experiment is to measure acceleration on a freely falling object assuming the only force acting on the object is gravitational force.
All dense objects in free fall have the same acceleration, which is known as the acceleration due to gravity. The value of accelera...
There are many events concerning the rising and the falling of the Berlin Wall, I will attempt to explain some of them in my following report. The person responsible for the rise of the Wall was Walter Ulbricht. He was a longtime member of the German Communist Party. After 1958 the German Democratic...

Acceleration Due to Gravity
Have you ever wondered why items always speed up when they are falling? Well it all has to do with acceleration due to gravity. Acceleration is the rate at which an object changes its velocity. Acceleration can be calculated by finding the change in velocity and dividin...

Is gravity always 9.8m/s2??
INTRODUCTION: A simple pendulum consists of a mass m swinging back and forth along a circular arc at the end of a string of negligible mass. A pendulum is a weight suspended from a pivot so that it can swing freely. Gravity is the pull that two bodies of mass exert on on...
