Multiple Choice

Which form of energy comes from eating food?

• Mechanical

• Chemical

• Thermal

• Sound

Multiple Choice

What type of energy comes from the sun?

• Solar

• Mechanical

• Electrical

• Chemical

Multiple Choice

All types of energy can be sorted into two types:

Potential Energy and _______ Energy

• Potential

• Chemical

• Kinetic

• Solar

​Potential Energy

• ​POTENTIAL ENERGY is energy that is stored and waiting to be transferred.

  It is the energy that an object has based on its height and position.

  Potential Energy = mass x height x gravity

• ​The higher the object, the more potential energy.

​Examples of P.E.

​

• Standing at the edge of a diving board (gravitational p.e)

• A vase on the top shelf of a book shelf (gravitational p.e)

  Energy stored in your food (chemical p.e)

  Stretch rubberband (elastic p.e)

  An inflated balloon

  When your ferris wheel cart is at the top

  When you sit at the top of the top of the giant slide (gravitational p.e)

Multiple Choice

What is Potential Energy?

• The energy an object has due to its position or condition.

• The energy an object has due to its chemical composition.

• The energy an object has due to its motion.

• The energy as object has due to its atomic structure.

Multiple Choice

What spot would the roller coaster car have the MOST potential energy?

• A

• B

• C

• D

• E

​Kinetic Energy

• ​The amount of energy something has due to its motion.

• An objects kinetic energy is affected by an objects mass and speed. The faster an object moves the more kinetic energy the object has. 

   Increase speed --> increase kinetic energythe amount of energy an object has due to its motion

​Examples of K.E.

• a boulder rolling down a hill

  a basketball falling to a net

  a moving car

  a glass falling on the floor

  an airplane in flight

  Riding a bike
