A scientific lander on an airless moon drops a tool from rest off the edge of a crevasse. The acceleration due to gravity on this moon is 1.5 m/s2.
The tool falls for 4.0 s before hitting the bottom.
Describe the key characteristics of a speed-time graph for this falling tool from t=0t = 0t=0 to t=4.0 st = 4.0\text{ s}t=4.0 s (state the starting point, the shape of the line, and the coordinates of the final point).
Determine the distance fallen by the tool.
Describe the shape of a speed-time graph for a light feather dropped from a height on Earth, where air resistance is significant.
Explain the difference between distance and displacement. Include the words vector and scalar in your explanation.
