We say that linear increasing in position is t he result of constant velocity which means zero acceleration. Red line shows nonlinear increasing and black line shows linear increasing. This position time graph is an example of increasing position in negative direction. We will solve more examples using graph for deep understanding and analyzing the motion from the graphs.ģ. The important thing is that you must know the relations, meaning of the slopes or area of the graphs. You can say more things about the motion of the object by just looking of the graph. If there is no change in position then there is no velocity or vice versa. You can easily see it from the graph, but I want to show the calculation of this and it gives us same result.
For example, in this example in the interval (3s-5s) position does not change. In graph problems you should be careful while reading it. We should first find the slope of the curve and calculate the velocity.Įxample Using the given graph find the velocity of the object in intervals (1s – 3s) and (3s – 5s).
We can also find the velocity of the object from this graph. As a result of this change graph has curved line not linear. Position is increasing positive direction. Which is the equation we use in calculation of the velocity.Ģ.
We just look at the slope of the graph and find the velocity. Now, we use this graph and make some calculations.įrom the given graph we calculate velocity there is another way of this calculation. If it was not constant we would see a curved line in our graph. We understand from this linear increasing, our velocity is constant. We observe that position is linearly increasing in positive direction with the time. As you see on the graph, X axis shows us time and Y axis shows position. They give us much information about the concepts and we can infer many things.
