Principle
The students should measure length, diameter, and hole depth of various objects with a measuring tape and/or vernier caliper as possible. In doing this they should choose and use the more suitable measuring device. The results should be entered in the ...
The student should count the oscillations of a pendulum while timing them with the aid of a stopwatch. To determine the dependence of the oscillation period on the length of the pendulum is shortened by 50% in the second part of the experiment. ...
1. The students should determine the mass of solid bodies with the aid of a balance.
2. The measurement of the mass of liquids can only be performed using a container. The students should determine the mass from the difference of two m ...
The students should determine the volume of 3 solid bodies. In doing this they should know that the cubic meter (m3) is the unit of volume and also that the term liter (l) is very common.
In the previous experiments on determination of mass and volume (ME 1.3 and ME 1.4), the students have learned that both metal columns have the same volume but different masses. They know that the two objects consist of iron and aluminium. Obviou ...
In the determination of the density of solids in Experiment ME 1.5, the density was determined as the quotient of mass and volume from a weighing to determine the mass and measurement of volume by different methods. As a prerequisite for this experime ...
The density of gases can, in principle, be determined in the same way as for solid bodies and liquids: by measuring the mass, the volume and forming the quotient.
Since the density of gases is much less than that of solid bodies or ...
The students should become acquainted with the dependence of the reading of spring balances on their orientation and with their adjustment.
With the spring balance adjusted for use in the normal vertical position, the weight F in N ...
1. The students should learn with the help of the spring balance that a force on a body can only be exerted when a counterforce acts on it simultaneously.
2. Using two spring balances, the students should experimentally determine that the fo ...
The students are to determine the weight which a mass experiences in the earth's gravitational field with a spring balance. They should know that force is measured in N = kg m?s2 and recognize that weight is proportional to mass.&nbs ...
The students should verify the declaration of Hooke's Law, i.e. the proportionality of force and extension within the elasticity range of an elastic body, with measurements on 2 helical springs having different spring constants. These springs will be ...
The students should add a scale to an uncalibrated spring balance by loading it with mass pieces.
In doing so they should know that a mass of 100 g represents a weight (force) of 1 N in the gravitation field of the earth.
On the one hand, the students should investigate the effect of two forces acting in the same direction on a mass piece; on the other hand, the effect of two forces acting in opposite directions on it.
From the comparison of the two measured ...
Based on their knowledge of Experiment ME 2.7, the students should determine the direction and magnitude of the resultant force Fr which replaces the two different forces F1 and
