To get any object Essay Example for Free

To get any object EssayWith your experiment you dont mention anything about lordly or measuring the force. All you have measured is the (average) period of the object moving in a locomote. From this you can calculate the average speed and acceleration. To turn this into an investigation you would need to measure the force draw the tip into the circular path. i. e. the tension in the pull. At the moment, if you put more effort in the bung will go faster, even if you dont change the radius of the circle, or the mass of the bung. One way to do this would be to include a spring of suitable strength into the weave and you could possible measure the offstage of the spring as you tailspin it around to estimate the force. Another method Ive seen personad is to have the string pass through a tube. On the bottom end of the string you attach a weight. You crook the bung around above your head whilst holding the tube until the forces are balanced. If you spin it too tardily the we ight drops down, if you go too fast it rises up.You need to adjust the speed of spinning until the weight balances at the correct point. Results There is a fairly simple saying for cicular motion. F = (m X v2) / r F = force (Newton) m = mass of bung (kg) v = speed of bung (m/s) r = radius of circle (m) You must make sure you use the correct units (m not cm, kg not g) to get the reflection to work correctly. The Force is constant 90 gram = 0. 9 Newton approximately. The mass of the bung is likewise constant.You can work out the speed using the formula speed = withdrawnness / time distance = circumference of circle X 10 time = time for 10 complete revolutions. Analysis lap of circle = 2 X pi X r If you rearrange the circular motion formula you get v2 = (F/m) X r F/m is a constant. Conclusions So a graph of V2 (on the y axis) plotted against r (x axis) should give you a straight mental strain. The gradient is equal to (F/m).it is a straight line which means the graph and the res ults are correct and they are ok and you will be able to use these for a future reference when explaining the stuff in the anlysis. Another method Ive seen used is to have the string pass through a tube. On the bottom end of the string you attach a weight. You twirl the bung around above your head whilst holding the tube until the forces are balanced. If you spin it too behind the weight drops down, if you go too fast it rises up. You need to adjust the speed of spinning until the weight balances at the correct point.
