• To measure temperature changes

• To observe color changes

Fill in the Blanks

Fill in the blank: The investigation question asks, 'How can

cause objects to have kinetic energy?'

Multiple Choice

What is the difference between potential energy and kinetic energy in the context of magnetic fields?

• Potential energy is stored energy due to position, while kinetic energy is the energy of motion.

• Potential energy is the energy of motion, while kinetic energy is stored energy due to position.

• Both potential and kinetic energy are types of energy that do not relate to magnetic fields.

• Potential energy and kinetic energy are always equal in magnetic fields.
