Question

which of the following statements is the best definition for potential energy?
the energy that is stored in an object.
the total amount of matter in an object.
the energy an object has by being in motion.
a measure of how far an object is moving.
what happens to the kinetic energy (k.e.) of a moving object after the collision?
the k.e. of the moving object increases.
the k.e. of the moving object is transferred to another object.
the k.e. of the moving object is destroyed.
the k.e. of the moving object is transformed into matter.
use the figure and information below to help you answer questions 5 & 6:
elevation = the distance from sea level
density = the amount of air particles in a certain area
low density = fewer air particles
high density = more air particles

Explanation:

• For the first question:
• Potential energy is defined as the energy stored in an object due to its position or state. The option “The energy that is stored in an object” aligns with this definition.
• “The total amount of matter in an object” is the definition of mass, not energy.
• “The energy an object has by being in motion” is the definition of kinetic energy.
• “A measure of how far an object is moving” is related to speed or distance, not potential energy.
• For the second question:
• According to the law of conservation of energy, energy is neither created nor destroyed. In a collision, the kinetic energy of a moving object is transferred to another object (it can also be converted into other forms like heat or sound due to friction etc., but among the given options, transfer is the most appropriate).
• The kinetic energy does not increase on its own after a collision (unless there is an external energy input, which is not indicated here).
• Energy is not destroyed (violates conservation of energy law).
• Kinetic energy is a form of energy and is not transformed into matter (matter - energy conversion is a different concept like in nuclear reactions, not relevant here).

Answer:

• First question: The energy that is stored in an object.
• Second question: The K.E. of the moving object is transferred to another object.
