Majority of the candidates failed to convert 0.53 cm to metre correctly. Below is an example of a distance-time graph, if it is a straight horizontal line than the body is stationary, its speed is zero, if the line is diagonal than its moving with a constant. So it will tell us about the journey made by a body and its speed. solve worded problems with the aid of diagrams. Distance-time graph is the plot of distance travelled by a body against time. determine unknown parameters from graphs of motion for example, area under displacement-time graph represents average velocity of the moving object. Part (d) In this question, area under the Force-Extension graph is required. describe the motion of an object (uniform and non-uniform) from a ticker tape and record graphs. Part (c) Many candidates drew the velocity-time graph correctly and determined the total distance travelled but some were not able to give correct calculation of deceleration.
#MOTION GRAPH PHYSICS HOW TO#
Lets consider how to draw a set of graphs for the.
Also, ‘Reaction’ is not accepted without ‘Normal’. Graphs can give us a lot of information about a particular motion. In view of the question, correct force and wrong direction will only attract. Part (b) Many candidates attempted this question and supplied the correct response. Some candidates used ‘rate’ and ‘change’ respectively to score zero. Many candidates supplied the correct definition but others failed in providing key words like increase velocity. Part (a) This was one of the popular choice of the candidates but the recorded performance was fair. These tools allow other aspects of motion such as acceleration and displacement to be determined or modelled. Negative slope means the motion is in the negative direction. Positive slope means the motion is in the positive direction. Constant velocity is explained by the straight line while acceleration is explained by the curved lines. The figure above illustrates force - extension graph for a stretched spiral spring. The motion of objects can be analysed using equations and graphs. Therefore, following are the takeaway from the displacement time graph: Slope is equal to velocity. Welding & Fabrication Eng.Craft Practice.Block Laying, Brick Laying and Concrete Works.
