C
The total energy of the system is maintained as energy is transformed.
Micah is investigating the transformation between potential and kinetic energy within a system. He uses a swinging pendulum in his investigation. He records his observations of the pendulum at different positions and creates the table below.
KINETIC AND POTENTIAL ENERGY OF A PENDULUM
Position Kinetic Energy (Joules) Potential Energy (Joules)
1 0 50
2 25 25
3 50 0
4 25 25
5 0 50
Which statement BEST describes the energy transformation in Michah's investigation?
A
The total energy of the system changes as energy is added to it.
B
The total energy of the system increases as kinetic energy is created.
C
The total energy of the system is maintained as energy is transformed.
D
The total energy of the system decreases as potential energy is destroyed.
