Kinetic Energy Flashcards
What is Kinetic Energy?
The energy an object has because it is moving.
What two things affect the amount of Kinetic Energy?
The mass (weight) of the object and its speed.
What happens to an objects Kinetic Energy when the speed increases?
The Kinetic Energy increases because the object is moving faster.
What happens to the Kinetic Energy if the mass increases?
The kinetic energy increases.
if a heavy object and a light object is moving at the same speed which object has more kinetic energy?
The heavy object has more kinetic energy because it has more mass.
how does kinetic energy affect molecules in a substance?
The more kinetic energy molecules have, the faster they move. This affects temperature, state of matter, and other properties.
what happens to the kinetic energy of molecules when a substance gets heated up?
the molecules move faster and kinetic energy increases.
how is kinetic energy related to temperature?
higher temperatures mean higher kinetic energy because molecules move faster at higher temperature.
what happens to kinetic energy when the object slows down?
The kinetic energy decreases because the object is moving slower.
