Comprehension Passage
Directions: Read the following paragraph and answer the questions below.
The work-energy-power concept in physics is crucial for understanding various phenomena. Work refers to the action of a force over a distance, which results in energy transfer or transformation. Energy, an intrinsic property of a system, can exist in different forms such as kinetic energy (due to motion) and potential energy (due to position or state). Power is defined as the rate at which work is done or energy is transformed. Understanding these principles can help us comprehend how machines work, how energy is converted in various processes, and the efficiencies of these processes.
If the speed of an object is tripled, what happens to its kinetic energy?
1
The kinetic energy remains the same.
2
The kinetic energy is halved.
3
The kinetic energy is tripled.
4
The kinetic energy increases nine times.
