In this experiment the main goal is to examine the correlation between position, velocity, time, and acceleration of objects, moving in one or two dimensions. Each and every experiment will be conducted under different conditions. For example, the first experiment requires a constant force (gravity) to act on the object, the picket fence. This experiments other condition is that we neglect friction. This object should be in nearly ideally circumstances. In the second experiment, the conditions are slightly different… In the third experiment, projectile motion… Experiment # 1 – Measuring the Acceleration of Gravity The object in motion is said to be in free fall. That is because the only force that is acting on the object is said to be the…

In this lab, we observed gravitational acceleration of an object. The tools and materials included a metal track, the car for the track, a piece of index card, a pasco glx device with a photogate sensor, and an object to elevate the ramp. First, the lab group arranged the materials for the experiment. We elevated the ramp up a small angle. The Lab determined the total distance the car must travel to the photogate was 30 centimeters. We then measured a small “flag” that was made from an index…

A ball, and a feather dropped at the same height will hit the ground at the same time when placed in a vacuum space. This is because acceleration of motion is the same for both object, and in this experiment, we are going to calculate accelerated motion using inclined planes. In this experiment, we will see whether “distance traveled is directly proportional to the square of the time”, and “if speed of a falling object depend only on the height from which it falls”. This experiment will give us…

Research: According to Newton 's Second law when force is increased acceleration increases assuming that mass stays constant. a=F/m Purpose: The purpose of this lab is to prove when force increases acceleration also increases. The independent variable is amount of force applied to the Lenny Board and the dependant variable is the acceleration of the Lenny Board. 3 controlled variables are mass, surface of testing, and the Lenny Board (the weight, the amount of grease on the bearings, ECT)…

Graphs of Position, Velocity and Acceleration The use of graphs is very common in science, statistics, economic and etc; in physics the graphs are use to illustrate and compare quantitative data of motion, time, velocity, etc. The graph illustrates the trend accurately, also the trend can be use to predict future outcomes. Graphs are a useful tool to have a efficient description in less words. The Graphs of Position Graphs of position are a way to represent motion of an object or…

velocity and acceleration, the quantities involved in linear kinematics. Graph 1 (distance vs. time) suggests a commonsensical relation - longer distance yields longer time. The only exception is at 1.0 m, where its time value (0.42 s) is less than that of a shorter distance (0.5s for 0.5 m distance). Average time was used to construct the graph, and there were only three trials for each testing height. Therefore, a bad trial could considerably affect the average time, in this case is 1.0 m,…

It is divided in two phases, the stance phase and the swing phase. During the stance phase, the lower extremity is in contact with the ground. This phase is formed by 5 different stages (the Heel Strike, Foot Flat, Mid Stance, Heel Off and Toe Off) which form the whole movement. In contrast, during the swing phase, the current limb, is not in contact with the ground. This phase has three stages ( Acceleration, Mid Swing and Deceleration) that generates the entire movement. • The aim of…

To experimentally measure the downward acceleration solely due to gravity at the surface of the earth and with negligible air resistance on a free-falling object, a piece of clear plastic with evenly spaced black bars, labelled as a “picket fence,” was suspended from a string and dropped through a Photogate sensor. This software is used to measure the actual acceleration of gravity to compare it to the value provided by literature review. The Photogate sensor transmits an infrared beam of light…

Research Question 1 Hypothesis 1 Variables 1 Materials 2 Procedure 3 Background Information Motion is the change of position of an object with respect to time. The physical quantities velocity, acceleration, displacement, time and speed are used in the study of motion. If an object does not change position with respect to time, it is considered as stationary. Note that if an object is motionless, it does not necessarily mean that there is no force acting on it. Motion can also be studied by…

physics plays an important role. Newton’s second law of motion demonstrates the relationship between force, mass, and acceleration, explaining that the force is equal to the mass of an object times the acceleration. If we apply this rule to football, it can be concluded that although the mass (of the football player) is unlikely to be changed, the acceleration can be. The new Zero1 helmet was specifically designed to address the acceleration a player experiences during impact in order to…
