It is useful to understand some of the hallmarks of the style and understand the vocabulary used when describing minimalism. The following are features of minimalism in general, some of which are used in the set work and others are present in other minimalist works:

Confusion of Mass and Weight A few further comments should be added about the single force that is a source of much confusion to many students of physics - the force of gravity.

As mentioned abovethe force of gravity acting upon an object is sometimes referred to as the weight of the object.

Many students of physics confuse weight with mass. The mass of an object refers to the amount of matter that is contained by the object; the weight of an object is the force of gravity acting upon that object. Mass is related to how much stuff is there and weight is related to the pull of the Earth or any other planet upon that stuff.

The mass of an object measured in kg will be the same no matter where in the universe that object is located. Mass is never altered by location, the pull of gravity, speed or even the existence of other forces.

For example, a 2-kg object will have a mass of 2 kg whether it is located on Earth, the moon, or Jupiter; its mass will be 2 kg whether it is moving or not at least for purposes of our study ; and its mass will be 2 kg whether it is being pushed upon or not. On the other hand, the weight of an object measured in Newton will vary according to where in the universe the object is.

Weight depends upon which planet is exerting the force and the distance the object is from the planet. Weight, being equivalent to the force of gravity, is dependent upon the value of g - the gravitational field strength. On earth's surface g is 9.

On the moon's surface, g is 1. Go to another planet, and there will be another g value. Furthermore, the g value is inversely proportional to the distance from the center of the planet. So if we were to measure g at a distance of km above the earth's surface, then we would find the g value to be less than 9.

The nature of the force of gravity will be discussed in more detail in a later unit of The Physics Classroom. Always be cautious of the distinction between mass and weight. It is the source of much confusion for many students of physics.

Even on the surface of the Earth, there are local variations in the value of g that have very small effects upon an object's weight. These variations are due to latitude, altitude and the local geological structure of the region. Use the Gravitational Fields widget below to investigate how location affects the value of g.

Sliding versus Static Friction As mentioned abovethe friction force is the force exerted by a surface as an object moves across it or makes an effort to move across it. For the purpose of our study of physics at The Physics Classroom, there are two types of friction force - static friction and sliding friction.

Sliding friction results when an object slides across a surface. As an example, consider pushing a box across a floor.

The floor surface offers resistance to the movement of the box. We often say that the floor exerts a friction force upon the box.

This is an example of a sliding friction force since it results from the sliding motion of the box. If a car slams on its brakes and skids to a stop without antilock brakesthere is a sliding friction force exerted upon the car tires by the roadway surface.

This friction force is also a sliding friction force because the car is sliding across the road surface.

Sliding friction forces can be calculated from knowledge of the coefficient of friction and the normal force exerted upon the object by the surface it is sliding across.

The coefficient value is dependent primarily upon the nature of the surfaces that are in contact with each other. For most surface combinations, the friction coefficients show little dependence upon other variables such as area of contact, temperature, etc. The more that surface molecules tend to adhere to each other, the greater the coefficient values and the greater the friction force.

Friction forces can also exist when the two surfaces are not sliding across each other. Such friction forces are referred to as static friction. Static friction results when the surfaces of two objects are at rest relative to one another and a force exists on one of the objects to set it into motion relative to the other object.GCSE French helps students develop their language skills in a variety of contexts and a The examboard used is AQA and this qualification counts towards the www frenchrevision co uk - Past papers and example exercises fromexam.
