How would your energy graphs look differently if the mass was 1 kg instead of 0.5 kg?
PE=mgh. So if the mass increased from 0.5 kg to 1 kg, the potential energy would increase by a factor of 2 since the mass doubles while the other two variables remain unchanged. The double would cause the Potential Energy vs Time graph to have a steeper slope and be closer to vertical.
KE=1/2mv^2. So if the mass increased from 0. kg to 1 kg, the kinetic energy would also increase by a factor of 2 since the mass doubles while the velocity remains unchanged. The double would cause the Kinetic Energy vs Time graph to have a steeper slope and be closer to vertical.
ME=KE+PE. Since the potential and kinetic energy both double, the mechanical energy doubles too. The shape would remain a harmonic motion, but the shape would be stretched vertically by a factor of 2.
