# Physical Science Worksheet: Conservation of Energy 2

The law of conservation of energy states that energy cannot be created or destroyed, only changed from one form to another. This law applies to physical science worksheets for conservation of energy and forms the core of many scientific theories. In this worksheet, we will explore the law of conservation of energy by looking at a few examples.

## Example 1: Car Moving Down a Hill

In this example, we will consider the motion of a car going down a hill. The car starts at the top of a hill and moves down the hill due to the force of gravity. As it moves down the hill, its kinetic energy increases as its potential energy decreases. However, the total energy of the car remains constant throughout the descent, demonstrating the law of conservation of energy.

## Example 2: Ball Rolling Along a Flat Surface

In this example, we will consider the motion of a ball rolling along a flat surface. The ball starts from rest and moves along the flat surface due to the force of gravity. As it moves along the surface, its kinetic energy increases as its potential energy stays constant. This demonstrates that the total energy of the ball remains constant, once again demonstrating the law of conservation of energy.

## Example 3: Pendulum Swinging

In this example, we will consider the motion of a pendulum swinging. The pendulum starts from rest and swings due to the force of gravity. As it swings, its kinetic energy increases as its potential energy decreases. However, the total energy of the pendulum remains constant throughout the swing, once again demonstrating the law of conservation of energy.

The law of conservation of energy states that energy cannot be created or destroyed, only changed from one form to another. This law applies to physical science worksheets for conservation of energy and forms the core of many scientific theories. The three examples in this worksheet demonstrate how the law of conservation of energy can be applied in real-world examples. This worksheet is a great way to learn and understand the law of conservation of energy.
