Introduction

Energy is a fundamental concept in physics that describes the ability to do work. There are various types of energy, including kinetic energy, potential energy, thermal energy, and more. In this article, we will explore the concept of energy and determine the type of energy a ball rolling down a hill possesses.

What is Energy?

Energy is the ability to do work, which can be defined as the transfer of energy from one object to another through a force. Energy can take various forms, including kinetic energy, potential energy, thermal energy, and more. The total energy of an object is the sum of its kinetic energy and potential energy.

Kinetic Energy

Kinetic energy is the energy of motion. It is the energy an object possesses when it is moving. The kinetic energy of an object is directly proportional to its mass and the square of its velocity. The formula for kinetic energy is:

KE = (1/2)mv^2

where KE is the kinetic energy, m is the mass of the object, and v is its velocity.

Potential Energy

Potential energy is the energy an object possesses due to its position or configuration. It is the energy an object has when it is at rest. The potential energy of an object depends on its height, mass, and the acceleration due to gravity. The formula for potential energy is:

PE = mgh

where PE is the potential energy, m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object.

A Ball Rolling Down a Hill

Now, let's consider a ball rolling down a hill. As the ball rolls down the hill, its potential energy is converted into kinetic energy. The ball's potential energy is due to its height, and as it rolls down the hill, its height decreases, and its potential energy is converted into kinetic energy.

Which Type of Energy Does a Ball Rolling Down a Hill Possess?

As the ball rolls down the hill, its potential energy is converted into kinetic energy. Therefore, the ball rolling down a hill possesses kinetic energy.

Conclusion

In conclusion, a ball rolling down a hill possesses kinetic energy. The ball's potential energy is converted into kinetic energy as it rolls down the hill. This is a fundamental concept in physics that describes the conversion of energy from one form to another.
