A student examines the graph shown below comparing two properties of a single wheeled cart rolling along a ramp.
A graph has an untitled increasing y-axis and increasing height of a wheeled cart on the x-axis. A line begins at the origin and extends at a 45 degree agree for the length of the graph.
Based ONLY on this graph, which label should be used for the vertical (y) axis?
A.
mass
B.
kinetic energy
C.
speed
D.
potential energy

D. potential energy
Reason: gravitational potential energy (U = mgh) is directly proportional to height, giving a straight line through the origin. Mass is constant (horizontal line), speed varies like sqrt(h), and kinetic energy would not produce a straight line increasing with height.
