Question

what evidence does this graph provide to support the law of conservation of energy? Provide numerical data.

Answer 1

Step-by-step explanation:

1. in any time the sum of Kinetic and Potential energies is the same value;

2. there are 4 points in interval from 0 to 50 seconds (see the attachment) and:

- when t=0, then Kinetic energy is 0 and the Potential one is 500 [J];

- when t=20, then Kinetic energy is 200 and the Potential one is 300 [J];

- when t=25, then Kinetic energy (250[J]) equals the Potential one(250[J]);

- when t=50, then Kinetic energy is 500 and the Potential one is 0.
