Finding the density of Air
(Length: 0.9 Pages) Finding the density of Air The density of air In this experiment we are to measure the density of air. It is a quite simple experiment, you learn how important it is to measure exact and be aware of the sources of error when measuring such small quantities. The whole idea is that you know the mass ...

HOW THE RESISTANCE EFFECTS A WIRE
(User Rating: 4.92 | Length: 9.0 Pages) HOW THE RESISTANCE EFFECTS A WIRE Experiment 3: Aim: How resistance depends on the material of the wire. Hypothesis: I hypothesis that I will only need to induce two Voltages of 2v and 3v to find the results I need. I predict that I will only need to use two different voltages because the resistanc ...

Investigation into the electric resistance of different material
(User Rating: 6.71 | Length: 2.9 Pages) Investigation into the electric resistance of different material Planning Aims and hypotheses This investigation is designed to look into the resistance of different material in the form of wires and their conducting capability in different shapes. In order to do so, the materials are to be tested ...

Measuring Atmospheric Pressure
(Length: 0.5 Pages) Measuring Atmospheric Pressure Measuring Atmospheric Pressure Aim: To measure the atmospheric pressure in Jonkoping today, by a simple lab. Apparatus: One plastic hose. Water (colored with MnO4-). A bucket. Procedure: First, we filled a bucket and the hose with the colored water. Then my friend wen ...

Measuring the velocity of light
(User Rating: 4.25 | Length: 1.0 Pages) Measuring the velocity of light The aim of this experiment is to measure the speed of light in an experiment available to do at school. The principle is quite simple. Let a ray of light strike a rotating mirror that reflects the light three meters away to a second mirror, so that the light is refle ...

Ohm's Law
(User Rating: 3.64 | Length: 0.4 Pages) Ohm's Law Ohm's Law The aim of this experiment is to verify Ohm's law; V = IR. And this is done quite easy with use of: * one potentiometer * one voltmeter * one ammeter * and a battery We simply connected the components as shown in the diagram below (fig 1). Then we started to measure, ...

Practical investigation into Viscosity in liquids(Stokes Law)
(User Rating: 4.75 | Length: 6.6 Pages) Practical investigation into Viscosity in liquids(Stokes Law) Introduction When dealing with fluid/mechanical systems, it is important to know what affects the rate of descent of an object through a liquid. There are many factors that affect the descent of an object through a liquid such as: 1) Tem ...

Projectile Problem
(User Rating: 3.60 | Length: 1.5 Pages) Projectile Problem Projectile Problem The problem to solve was to calculate how far a ball would 'fly' (y), when dropped in an sloping rail that ends 91.3 cm above the floor (see figure 1). The goal for us to reach to was that our teacher should place a cup at any distance (within the range ...

Projectiles
(User Rating: 10.00 | Length: 3.8 Pages) Projectiles Planning The experiment is to determine the horizontal motion of a projectile when launched from a 'ski slope´ at different speeds. It is thought that the rate at which the ball bearing is released from the slope will affect how far it travels in a horizontal direction. The height u ...

Resistance and the Wheatestone bridge
