I believe wearing a school uniform is an obstacle of children’s right to individuality and self-expression. Everyone is unique‚ and so making children wear a school uniform takes away their individuality and personality. Maybe this discourages them from performing to their fullest potential‚ and exceeding to higher levels in their subjects? I think most school uniforms are hideous and unappealing‚ and being forced to wear something that is not comfortable to a child is not good for their mental

The discussion about school uniforms has been going on for a very long time through schools in the United States. Some schools believe uniform helps with behavior problems and other believe no uniform is a way to express oneself. As a tenth grader at Orange High School‚ I personally am not a fan of uniform because I like to be creative with my outfits the way I dress is a very big extension of the kind of person that i am. Without that who would we all be? Uniform does not give students a sense

Introduction The purpose of this experiment is to determine whether a change in mass affects the acceleration of the cart. The independent variable is the mass of the weight and the dependant variable is the acceleration. I do not think there is a control in the experiment because we do not know an absolute result with any of the masses of the weight. Besides‚ if we used 0g as our control‚ the cart won’t even move. Hypothesis Under these conditions I believe that the results shown in the distance

Controlled variables: 1. The lighting was kept constant during the complete test. No additional light sources were added throughout the experiment‚ nor were any light sources removed throughout the experiment. This minimized the errors involved with trying to read and record the indicated measurements on the ticker tape‚ as well as the ability to analyze the experiment. 2. The same person measured and recorded the height and length of the incline plane and level horizontal track to ensure consistency

Uniform Circular Motion – a constant motion along a circle; the unfirom motion of a body along a circle Frequency (f) – the number of cycles or revolutions completed by the same object in a given time; may be expressed as per second‚ per minute‚ per hour‚ per year‚ etc.; standard unit is revolutions per second (rev/s) Period (T) – the time it takes for an object to make one complete revolution; may be expressed in seconds‚ minutes‚ hours‚ years‚ etc.; standard unit is seconds per revolution

Its magnitude is given by the equation: F = mrω2 When an object is whirled in horizontal circular motion in mid-air with a piece of string (as shown in figure 1 above)‚ the centripetal force on the object is provided by the horizontal component of tension in the string: 2 =>2 (since r = L)
