to show that the acceleration is proportional to the force causing the motion. Theory Newton’s second law of motion states that the acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to the total mass. a = net force/ total mass If an object is acted on by a net force ‚ it will experience an acceleration that is equal to the net force divided by the mass. Because the net force is a vector‚ the acceleration is also a vector‚

Reid Purpose: To determine both qualitative and quantitative properties of the motion of a cart on an inclined plane on position vs. time‚ velocity vs. time and acceleration vs. time graphs. Question: Which properties of the cart’s motion can be determined from examining each of the three graphs? Hypothesis: The predictions on the type of motion demonstrated by the cart-qualitatively- are shown below.

Lab 3: Newton’s Second Law: The Atwood Machine Introduction: In the study of physics a lot of the basics were put in place by Isaac Newton. Out of the 3 laws of motion he had declared the second law states that force equals mass times acceleration (F=ma). The Atwood machine is a machine that has a pulley in the air and a string running through the pulley‚ some kind of mass is suspended by each end of the string. When the suspended masses are unequal‚ the system will accelerate towards the direction

LAB WRITE-UP NAME: Gabriel-Ohanu Emmanuel PARTNER: Baptiste Gilman TITLE: Graph Matching PURPOSE: The purpose of the experiment was to analyze the motion of a student walking along a straight line in front of the motion detector moving back and forward with different speed trying to match the graph provided. To also understand and interpret graphs of distance vs time and velocity vs time. To also know what the slopes of the each graph represent which tells how far the student travelled

We will assume that Up is the positive direction and Down is the negative direction. Case 1: No acceleration of elevator If the acceleration of the elevator is zero‚ then there are two possible scenarios; the elevator can be at rest (stationary‚ zero velocity) or moving with a constant speed (no acceleration if velocity does not change).

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
