#Freefall position vs time graph free

Since the slope of any velocity versus time graph is the acceleration of the object, the constant, negative slope indicates a constant, negative acceleration. An object that is moving in the negative direction and speeding up is said to have a negative acceleration. A further look at the velocity-time graph reveals that the object starts with a zero velocity (as read from the graph) and finishes with a large, negative velocity that is, the object is moving in the negative direction and speeding up. Since a free-falling object is undergoing an acceleration (g = 9,8 m/s/s, downward), it would be expected that its velocity-time graph would be diagonal. As learned earlier, a diagonal line on a velocity versus time graph signifies an accelerated motion. Observe that the line on the graph is a straight, diagonal line. If the velocity and time for a free-falling object being dropped from a position of rest were tabulated, then one would note the following pattern The value of the acceleration of gravity (g) is different in different gravitational environments (different planets). By so doing, we will be able to better focus on the conceptual nature of physics without too much of a sacrifice in numerical accuracy.

We will occasionally use the approximated value of 10 m/s/s in The Physics Classroom Tutorial in order to reduce the complexity of the many mathematical tasks that we will perform with this number. There are slight variations in this numerical value (to the second decimal place) that are dependent primarily upon on altitude. The numerical value for the acceleration of gravity is most accurately known as 9.8 m/s/s. A matter of fact, this quantity known as the acceleration of gravity is such an important quantity that physicists have a special symbol to denote it - the symbol g. It is known as the acceleration of gravity - the acceleration for any object moving under the sole influence of gravity. This numerical value for the acceleration of a free-falling object is such an important value that it is given a special name. A free-falling object has an acceleration of 9.8 m/s/s, downward (on Earth). It was learned in the previous part of this lesson that a free-falling object is an object that is falling under the sole influence of gravity. If an object travels downward and speeds up, then its acceleration is downward The fact that the distance that the object travels every interval of time is increasing is a sure sign that the ball is speeding up as it falls downward. All free-falling objects (on Earth) accelerate downwards at a rate of 9.8 m/s/s or 9.8 m/s^2 (often approximated as 10 m/s/s for back-of-the-envelope calculations).Free-falling objects do not encounter air resistance.There are two important motion characteristics that are true of free-falling objects:
