A student is trying to identify the different forms of energy described in the following chart:

Form of Energy
Description
Examples
Energy A
energy that travels in waves through space
light
radio waves
Energy B
energy that depends on the height of an object
a person at the top of a mountain
a book lifted above ground
Energy C
vibration or disturbance of matter through waves
vibrations from vocal chords
vibrations from stereo speakers
Energy D
potential and kinetic energy are the basic types
describes how much work an object can do
a speeding car
a pebble sitting at the top of a mountain

I think it's D..I'm not sure I'm sorry :( Try looking back through your lessons. It should have a great explanation for you. :)

To identify the different forms of energy described in the chart, you can look for the defining characteristics or keywords in each description. Let's go through each form of energy one by one:

Form of Energy A: This form of energy is described as traveling in waves through space. The examples given are light and radio waves. From this description, we can identify this form of energy as electromagnetic energy or electromagnetic radiation. This energy includes various types of waves, such as visible light, radio waves, microwaves, X-rays, and gamma rays.

Form of Energy B: This form of energy depends on the height of an object. The examples given are a person at the top of a mountain and a book lifted above the ground. Based on this description, we can identify this form of energy as gravitational potential energy. Gravitational potential energy is the energy an object possesses due to its height in a gravitational field.

Form of Energy C: This form of energy is described as a vibration or disturbance of matter through waves. The examples given are vibrations from vocal chords and vibrations from stereo speakers. This form of energy is identified as sound energy. Sound energy is produced when an object vibrates, causing particles in the surrounding medium (such as air, water, or solids) to vibrate, creating sound waves.

Form of Energy D: This form of energy is described as involving both potential and kinetic energy, and it determines how much work an object can do. The examples given are a speeding car and a pebble sitting at the top of a mountain. This form of energy is mechanical energy. Mechanical energy is the sum of potential energy (energy stored in an object's position) and kinetic energy (energy of motion).

By understanding the characteristics and examples provided for each form of energy, you can identify them as electromagnetic energy, gravitational potential energy, sound energy, and mechanical energy.
