Friction on the ramp Essay Example for Free

Friction on the ramp Essay As you can see from the graph, as h1 is increasing, the horizontal distance also increases. The graph is more or less a straight line because the horizontal distance travelled by the ball baring in each interval should more or less be around the same. However it didnt show that the y-component is directly proportional to the x-component. This could be of the inaccuracy of the equipment, measurement and air resistance when in travelling in the air and friction on the ramp. The accuracy of the meter ruler is quite poor when it comes to measuring the point at which the ball has landed. Therefore the uncertainties would be measuring precisely the point at which the ball baring had landed. It will be more or less i 1mm. The position for releasing the ball baring is another issue. If the ball is being released from a higher or lower position compared to the previous test, it will have an affect on the initial velocity when leaving the ramp. Higher velocity will result in a bigger horizontal component and therefore uncertainties would be more or less i 1mm. The total uncertainty would be i 2mm. The plastic ramp also creates a problem. The end of the ramp is difficult to maintain a precise horizontal position because of the bendiness of the plastic ramp. This is an important factor because it has an affect on the initial velocity and therefore will change the results. It will create a vertical acceleration if it bends resulting in an increase in the horizontal component. In theory, we have assumed that the air through which the projectile moves has no effect on its motion, a reasonable assumption at low speeds. However, for a greater speed, the disagreement between calculations and the actual motion of the projectile can be large because the air opposes the motion of the projectile. So, a bigger h1 means the projectile will be in the air for longer; therefore the air resistance will affect the projectile more and consequently will reduce horizontal distance travelled. I believe this is the reason that the line on the graph isnt directly proportional to the x and y components. Therefore in the absence of air resistance, I believe that the graph produced would be directly proportional to both x and y components. In order to calculate the theoretical range, we have to find the horizontal and vertical component separately. I can use the following equations to find out both of the horizontal and vertical components.

The Dental Profession Essay example -- dentistry

The Dental Profession    As a senior biomedical engineering student at RPI, I am   receiving a particularly well-rounded education in engineering,   complemented by studies in the sciences and humanities.   During   my sophomore year, I became interested in dentistry and began to   select courses that would prepare me for dental school.   While   this meant additional work, I improved my study skills, and I   have earned a grade point average of 3.4 over the last three   years.   Because of this rigorous course load, I will be   graduating this August instead of last May.   I had planned on   applying to dental school this fall for the 1988-89 entering   class, but after receiving your letter earlier this month and   subsequently speaking with the admissions office, I found that   it was still possible to apply for the September 2002 entering   class.      My interest in the health care field began while I was in high   school.   I was first introduced to many different aspects of the &...

A balanced approach Essay

It is our main concern to keep children safe from harm. Doing this can be very hard, as at the same time we need to encourage children and young people to experience risk and challenges. If we try to remove all risks from children’s lives we could be restricting their learning experiences. Some risks obviously need to be avoided, otherwise we wouldn’t be competent in our role of caring for children and young people. Obviously the risks we allow children and young people to take should be appropriate to age, needs and ability, and a balanced approach should apply. We should not be excessively risk adverse and encourage children to have more independence, therefore creating more confidence. By allowing children to use and access certain equipment such as a trim trail or climbing frame, and giving them rules and boundaries to follow whilst using the equipment allows them to take certain risks without taking excessive risks. See more: The Issues Concerning Identity Theft Essay The children that I work with understand that when they are allowed access to the trim trail, they must follow the rules. There have been instances when children have not followed the rules and then have ended up with minor injuries from falling. Children now know that if the rules are not followed they will be removed from the activity on that occasion. However, by allowing children and young people to take certain risks, we must also remember to avoid excessive risk taking, for example, we should encourage children not to swing on chairs, and always demonstrate to children and young people how to use equipment correctly, i.e. scissors. It is very important your children and young people to be given the opportunity to take risks and challenges in order for them to develop a sense of self awareness. They need to understand the importance of potential risks to themselves and others around them. Children need to be encouraged to think about what risks may arise and how they can be avoi ded, and how they may impact on others and themselves.
