1. If the Mechanical Energy of a ball that is thrown upward is 500 J in its maximum height, then its Mechanical Energy at the lowest point is:
2. If the Mechanical Energy is 500 J for a ball that was thrown upward in its maximum height, then its maximum kinetic energy is:
3. If the maximum kinetic energy for a ball that is thrown upward is 500 J, then its maximum gravitational energy is:
4. When a ball is moving with speed v to have kinetic energy of 100 J. If the speed is doubled and still have the same mass, then its kinetic energy is:
5. Two objects that have the same velocity, the first object has triple the mass of the other object, then the ratio of the kinetic energy of the first object to the other object is:
6. When a moving ball that is moving straight upward has 1000J mechanical energy and 200J kinetic energy, then its gravitational potential energy is:
7. A ball is at height 10m and has 100J Gravitational potential energy. If the height becomes 20 m, then is gravitational potential energy will become:
