freefall position and velocity time grapph

Look at the example given below to understand what we mean by the area under the graph.Įxample: Using the given graph calculate the displacement of the object for the interval (0s – 4s). time graph also gives us the displacement of the object. Since, the velocity times time gives us displacement the area under the velocity vs.

First, look at the definition of displacement How can we do this? Let’s think together. time graphs we can calculate displacement of the object. It can be said for this graph acceleration is zero because there is no change in velocity. We see the relation of velocity and time, how velocity is changing with time. What you see when you look at this graph? For instance, in this graph as it seen our velocity is constant, time passes but velocity does not change. We have talked about different kinds of motion such as, constant motion having constant velocity, accelerated motion like speeding up or slowing down.

One of them is area under the graph which gives the displacement and the slope which gives the acceleration. We can benefit from this graph by two ways. time graphs, x axis is time as in the case of position vs. It is really easy, you should just keep in mind that “slope shows the velocity”. I think they will help you in solving problems. We have seen various type of position vs. However, the blue and green lines show the linear decrease in position in positive and negative directions. Red line shows the position of the object which is slowing down in negative direction and black line shows the position of the object slowing down in positive direction. Now we talk about a little bit slowing down object’s graphs.įor example, in this given graph, our position is decreasing in different directions. Until now we saw graphics including speeding up motion in positive and negative directions. Moreover, nonlinear increase in the position is the result of changing velocity and it shows there is a nonzero acceleration. We say that linear increasing in position is the 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. 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. 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. time graph.Īs 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.
