Compare the processes by which a car and a human use "fuel" to perform work. What are the similarities?
Alenkinab [10]

A car needs to be fueled before it can set in motion to posses a given amount of kinetic energy.

<h3>What is energy?</h3>

Energy is the capacity of doing work. In physics, there exist different types of energy; among which are follows:

  • Kinetic energy: Kinetic energy can simply be defined as that energy a body posses due to its motion
  • Potential energy: , On the other hand, potential energy is the energy a body has due to its relative position.

Other forms of energy include:

  • Solar energy
  • Nuclear energy
  • Mechanical energy

So therefore, a car needs to be fueled before it can set in motion to posses a given amount of kinetic energy.

Therefore, kinetic energy is the energy which allows a car to be fueled before it can set in motion .
