The Acceleration of Gravity
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. A free-falling object has an acceleration…
Free Fall and the Acceleration of Gravity
Introduction to Free Fall A free falling object is an object that is falling under the sole influence of gravity. Any object that is being acted upon only by the…
Alternative Method for Trapezoids
An alternative means of determining the area of a trapezoid involves breaking the trapezoid into a triangle and a rectangle. The areas of the triangle and rectangle can be computed…
Calculating the Area of a Trapezoid
Finally we will look at a few example computations of the area for a few trapezoids. The solution for finding the area is shown for the first example below. The…
Calculating the Area of a Triangle
Now we will look at a few example computations of the area for a few triangles. The solution for finding the area is shown for the first example below. The…
Determining the Area on a v-t Graph
As learned in an earlier part of this lesson, a plot of velocity-time can be used to determine the acceleration of an object (the slope). In this part of the lesson,…
Determining the Slope on a v-t Graph
It was learned earlier in Lesson 4 that the slope of the line on a velocity versus time graph is equal to the acceleration of the object. If the object is moving with…
Relating the Shape to the Motion
As discussed in a previous part of Lesson 4, the shape of a velocity vs. time graph reveals pertinent information about an object's acceleration. For example, if the acceleration is zero, then…
The Meaning of Slope for a v-t Graph
As discussed in the previous part of Lesson 4, the shape of a velocity versus time graph reveals pertinent information about an object's acceleration. For example, if the acceleration is…
Speeding Up versus Slowing Down
Now how can one tell if the object is speeding up or slowing down? Speeding up means that the magnitude (or numerical value) of the velocity is getting large. For…
