Time and Velocity
1. Begin by making charts like the one below for this situation and each of the following b-d
a. The man walks slowly to the house from the origin.
Position –Time Graph
Graph increased with time and then become constant
Velocity-Time Graph
Graph increased and decreased with time and then become zero
Acceleration –Time Graph
Graph increased and decreased with time some time becomes positive and some tie negative then zero.
2. In red make a prediction for the distance-time, velocity-time and acceleration-time graphs for each situation.
b. The man is sleeping under the tree. When he wakes up he runs toward the house constantly speeding up as he goes.
Distance-time Graph increased with time and then become constant,
Velocity-time distance-time Graph increased with time and then decreases and become zero
Acceleration-time Graph increased with time and then decreases and become zero
c. The man steps outside the house pausing to lock the door. He then walks quickly for 3 meters then immediately slows down and walks the rest of the way at this slow pace to the tree.
Distance-time Graph increased then become zero then increases for 3 mints after that decreases and then become constant,
Velocity-time distance-time Graph increased then become zero then increases for 3 mints after that decreases and then become constant
Acceleration-time Graph increased then become negative then increases for 3 mints after that decreases and then become constant and zero.
d. The man walks steadily toward the tree, stops to pick up a leaf, turns and walks steadily toward the house slowing to a stop before he arrives.
Distance-time : first increases then constant then decreases.
Velocity-time distance-time: increases then decreasing then zero then increases
Acceleration-time: first increases then negative and zero then increases back and hen zero.
3. Run the simulation. Use MOVING MAN to verify or correct your
