Newton`s Second Law – Lab Report Name: Tasneen Ahsan Date: 19th November‚ 2012 Purpose To show how the acceleration of an object changes when‚ the mass changes and the net force is kept constant and when the mass is the same.. Hypothesis I predict that by changing the mass of the object will result in a change in the acceleration as Newton`s second law states that the magnitude of the acceleration of any object is directly proportional to the magnitude

Coulomb’s Law 1. Objective - To study the validity of Coulomb’s law on a simple electroscope. This will be split into two parts; first measuring the the force as a function of distance‚ and second we will look at how the magnitude and sign of the charges affect the force. 2. Theory- As is well known‚ like charges repel and opposite charges attract. That being said‚ the strength of those forces also depends on the distance between the two charges

flows through the wires‚ a magnetic field is induced in the space surrounding the loops of wire. This magnetic flux is designated by Bi . The strength of the magnetic field induced by the current at the center of the loops of wire is given by Amperes law: Induced Bi = [pic]. where μo is the permeability of free space and has the value of 4π x 10-7 N/A2‚ N is the number of turns of wire‚ I is the current through the wire‚ and R is the radius of the loop. When the wire loops of the tangent galvanometer

The Physics 500 Introduction: The purpose of this lab is to show how to calculate the average speed and acceleration in six different races. In order to find average speed you will need to use the formula s=d/t (s= speed‚ d=distance‚ t=time). On the other hand‚ for accelaration you will use the formula a= vf-vi/t (a=acceleration‚ vf=final velocity‚ vi= initial velocity‚ t=time). Average speed is how fast something is moving; the path distanced moved per time. Acceleration is the

Pendulum Raiyan Hassan SPH3U September 20‚ 2011 Introduction A pendulum is a device which consists of a mass attached to a string from a frictionless pivot which allows it to swing back and forth. In this experiment‚ the time it takes for a pendulum to go through a period is going to be measured. The time it takes for a pendulum to go through one period can depend on factors such as the length of the string‚ mass‚ or the degree in which the pendulum is released from (amplitude). In this

because physics theory says that objects free falling‚ where the only force acting on them is gravity‚ accelerate at the same rate no matter what their mass is. 4. The change in spacing of the dots tells us that the speed of the object is increased as it falls‚ because the spacing increases between the dots. Sample Calculations: 9.) 60 dots per second‚ 24 dots 24 dots ÷60 dots per second=.400 seconds t=.400 s - 11.) 50 gram= dt=v-bar‚ d=-.792 m ÷ t=.400 s = -1.98 m/s v-bar=-1
