The acceleration due to gravity changes as we move away from Earth, and the expression for gravitational potential energy must reflect this change. The total energy of a system is the sum of kinetic and gravitational potential energy, and this total energy is conserved in orbital motion.
Electrical energy.................
Answer:
C
What is the answer please help her
c. To increase power, you can increase the amount of work you do in a given amount of time, or you can do a given amount of work in less time.
Explanation:
- Power in physics is defined as the rate of energy is being transferred over a particular time. The rate or amount of energy transfer is the work done to an object whereas it is in a specified time.
- The formula to find the power is , Hence, to increase the power in a given system either you have to reduce the time by increasing the work or increase the amount of work in the given time.
