Energy Unit 4 part 3

Study the features of this diagram.  When  the slingshot is held in position as in the diagram, what kind of energy is present?

• Kinetic energy
• Potential energy
• electrical energy
• Electromagnetic energy

Which property of acids and bases do most acid-base indicators use?

• Acidds and bases give off specific tastes that are easy to recognize.
• Acids and bases can react with certain objects to wear them away.
• Acids and bases can react together to form salts.
• Acids and bases react with certain compounds to cause a change in color.

A student is going to compress the object shown in the diagram.  Which form of energy will the object gain when the object is compressed?

• electromagnetic
• mechanical 
• chemical 
• electrical

A mass hanging from a spring moves up and down. The mass stops moving temporarily each time the spring is extended to its fullest at position 2 and each timeit returns to its tight coil at position 4.Which answer choice best describes the type of energy the spring has at Position 1?

• Kinetic Energy
• Potential Energy
• Both potential and kinetic energy
• Neither potential or kinetic energy

As liquid water loses energy in the form of heat, the water begins to freeze.    Whatcauses freezing?

• Heat removes thermal energy from the liquid water and causes it to become an ice cube.
• The loss of thermal energy from the water causes it molecules to move slower.
• The loss of heat cuases the molecules in the ice cube to contract and forces them together
• The loss of heat cuases the molecules in the ice cube to contract and forces them together

Which of these choices best describes the thermal energy of a substance?

• the difference between the kinetic energy and potential energy of a substance
• the average kinetic energy of the particles that make up a substance
• the total of the kinetic energy of all of the p substance
• the kinetic and potential energies of all of the particles of a substance

True or False
