Work, Power, KE and U

Which of the following does not contribute to the potential energy of an object?

• height of the object above the Earth's surface
• gravitational constant or g of the Earth
• velocity of the object
• mass of the object

All energy that is in a moving object

• Mechanical 
• Plants
• Metallic
• Modeling

Stored energy or energy of position, this energy has “potential” to move (Example: Rock at top of hill)

• Solar Energy
• Mechanical Potential Energy
• Mechanical Kinetic Energy
• Heat Energy

Energy of motion, something is moving in all forms of energy for instance thermal, electrical, light & sound (Example: rock falling from top of hill)

• Chermical Energy
• Light Energy
• Mechanical Kinetic Energy
• Mechanical POtential Energy

Energy can neither be created nor destroyed, it just changes form.

• Law of Matter
• Law of Conservation of Energy
• Law of Light Energy
• Law of Solar Energy

W=F x d (Work (J) or Nm = Force (N) x distance (m)

• Wall Formula
• Word Formula
• Work Formula
• None of the above

At which point is potential energy greatest

• W
• X
• Y
• Z

As a pendulum swings from its highest to lowest position, what happens to its kinetic and potential energy? 

• Both the potential energy and kinetic energy decrease
• The potential energy decreases while the kinetic energy increases 
• The kinetic energy decreases while the potential energy increases 
• Bothe the potential energy and kinetic energy increase 

At which point is kinetic energy greatest 

• W
• X
• Y
• Z

When a pendulum swings, at which point is kinetic energy highest: 

• 1
• 2
• 3
• 4
