An inclined plane is a flat supporting surface tilted at an angle‚ with one end higher than the other‚ used as an aid for raising or lowering a load. Inclined planes are widely used to move heavy loads over vertical obstacles; examples vary from a ramp used to load goods into a truck‚ to a person walking up a pedestrian ramp‚ to an automobile or railroad train climbing a grade. Inclined planes are widely used in the form of loading ramps to load and unload goods on trucks‚ ships‚ and planes. Wheelchair

Their were two strong attempts to fight communism. These attempts were the Truman Doctrine and the Marshall Plan. These ideas go hand in hand making

Determining a Person’s Power through height/work Power is denoted by the formula‚ P = mgh/t. In lifting a bag‚ work is done. So in order to get power we recorded our weight‚ measured the weight of the bag‚ and the time it took to lift a bag. The experiment is done in two ways 1) with constant time and 2) with constant height. In this way‚ we can compare and know if there will be a difference in the amount of power exerted by a person if either time or height will be constant. The formulated

The extended family ended with industrialisation Prior to the industrial revolution families were drastically different to how they are today. Extended families and kinship economies played a large part in family life as all land was owned and farmed upon by relatives beyond that of the nuclear family and as such people were born into certain roles in family rather than this being based on achievements and qualifications as it is nowadays. These roles would be passed down through generations and

the United States had ever seen. It had devastating effects on the United States and virtually every other country in the world. The United States suffered through hard economic times until 1941‚ when the Depression officially ended. There is a lot of debate on what ended the Great Depression‚ some say FDR’s “New Deal” programs got the economy rolling again; others credit it to World War II. Without Franklin Delano Roosevelt’s “New Deal”‚ the United States would have never recovered as fast as it

Physics PENDULUM INVESTIGATION Aim of the investigation The aim of the pendulum investigation is to see what will happen if I change a variable whilst I swing a pendulum and see the effect which it has on the pendulums time to complete one whole swing (from where it starts‚ to the opposite end‚ and back again). This will give me an insight into what will effect the time of the swinging of the pendulum‚ be it weight‚ string length‚ the angle‚ or the swinging point. Planning my investigation
