Asked by .
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.
potential energy
D.
speed

C — potential energy.
Gravitational potential energy U = mgh is directly proportional to height (for constant mass and g), giving a straight line through the origin. Mass would be constant (horizontal line), kinetic energy and speed would not increase linearly with height for a rolling cart.
