![]() This can be shown in the given below diagram. The slope will be positive as there is a constant acceleration with time. If we plot a velocity-time graph of a body in free fall, due to a constant acceleration on the body, a straight line with positive slope to the time axis would be observed. This acceleration in case of gravitation is known to be acceleration due to gravity.Ī constant acceleration means that there must be a constant increase in the value of velocity of the object with respect to the time period. We know from Newton's laws that whenever a body is acted upon by a force, there must be a certain value of acceleration with the body. For a uniform motion, the paths under the graphs are straight lines (vertical, horizontal or slanting) but for a non-uniform motion. The moment a body is dropped, a force of gravity due to Earth pulls it towards its centre. In our constant velocity lab we used the motion sensor to measure the position of an object 100 times a second and plotted the data as a graph of position vs. graph or velocity-time graph, and (iii) acceleration-time graph. This acceleration is known as acceleration due to gravity.Ī body can be said to be in free fall when it is dropped from a certain height and is allowed to fall under the effect of gravity. Specific information is available there on the following topics: Acceleration. Moreover, when the position, velocity and acceleration of an object are graphed over the.

In this motion, a constant acceleration is applied on the body due to Earth’s gravitational force. The three graphs of motion a high school physics student needs to know are: Position vs. Hint: When we drop a body it will be in free fall motion under gravity. So here in this post, we have covered 3 graphs for free-fall: (1) Displacement-time graph (2) Velocity-time graph (3) Acceleration-time graph.
