/hich graph best shows the relationship between an object's mass nd its kinetic energy (assuming constant velocity)?
The appropriate graph to illustrate the relationship between an object's mass and its kinetic energy (assuming constant velocity) is a linear graph.
On the x-axis, we would plot the mass of the object, and on the y-axis, we would plot its kinetic energy. Since the kinetic energy (KE) of an object is directly proportional to its mass (m), according to the equation KE = 0.5 * m * v^2, where v is the velocity, the graph would have a straight line passing through the origin.
As the mass of the object increases, the kinetic energy also increases proportionally. Therefore, the slope of the line would be positive, indicating that the kinetic energy is directly proportional to mass.
