“INTRODUCTION TO ENERGY” WORKSHEET Name___ Date _______________ Part 1. The two basic types of energy Directions: Determine the best match between basic types of energy and the description provided. Put the correct letter in the blank. ____B_1. A skier at the top of the mountain (a) Kinetic Energy ___B__2. Gasoline in a storage tank (b) Potential Energy __A___3. A race-car traveling at its maximum speed (c) Both forms of Energy __C___4. Water flowing from a waterfall before it hits the pond below ___B__5. A spring in a pinball machine before it is released ___C__6. Burning a match ___A__7. A running refrigerator motor Part 2. Definitions of Energy. Directions: Write down the definition for each of the following terms. ENERGY: Can be changed from one form to another. Energy cannot be created or destroyed. KINETIC ENERGY: Energy of a moving object. POTENTIAL ENERGY: The energy in the matter due to its positions or the arrangement of its part. Part 3. Forms of Energy. Directions: Determine the type of energy for each form (Kinetic, Potential, or Both) and give an example. Form Definition Type (KE, PE, Example (for each or Both) type if both) Mechanical An object’s movement creates energy Kinetic Moving arrow (motion) energy Thermal (heat) The vibration and movement of molecules Kinetic Temperature energy Radiant energy Electromagnetic waves Kinetic Microwave Electrical energy Chemical energy Nuclear energy Sound energy Gravitational energy Movement of electrons Stored in bonds of atoms and molecules Stored in the nucleus of an atom; released when nucleus splits or combines Vibration of waves through material Energy of position or height Kinetic Potential Potential Kinetic Potential Lighting Food A star Speakers Rollercoaster Class__4 Part 4. Forms of Energy Continued Directions: Match the energy form(s) to the description provided. A few questions may have more than one answer. _______A______1. Falling rocks from the top of a mountain _______D______2. Release of energy from the Sun (a) Mechanical (b) Electrical ______E_______3. Energy released from food after it is eaten _______E______4.
