Vertical Motion and Free Fall Video Lessons

Concept

# Problem: A stone is thrown upward from the edge of a cliff, reaches its maximum height, and then falls down into the valley below. A motion diagram for this situation is given (Figure 1) , beginning the instant the stone leaves the thrower’s hand.Construct a graph corresponding to the stone's vertical acceleration, ay(t), taking the acceleration due to gravity as exactly 10 m/s2. Ignore air resistance. The unit of time is in seconds and the unit of displacement is in meters. In plotting the points, round-off the coordinate values to the nearest integer.

Acceleration is constant:

g = 10 m/s

At t = 0 s, g = 10 m/s2

At t = 2 s, g = 10 m/s2

At t = 4 s, g = 10 m/s2

At t = 6s, g = 10 m/s2
