Question

Identify the energy transformations in the following actions.

*Turning on a space heater
*Dropping an apple core into the garbage
*Climbing up a rope ladder
*Starting a car
*Turning on a flashlight

Answer 1

a)Mechanical to heat energy.

b)potential to kinetic energy

c)kinetic to potential energy

d)kinetic to heat energy.

Answer 2

According to the Law of Conservation of Energy, energy is neither created nor destroyed. It is only transferred through different forms of energy. For the following situations, the conversion of energy is as follows:

*Turning on a space heater = electrical energy⇒heat energy
*Dropping an apple core into the garbage = potential energy⇒kinetic energy
*Climbing up a rope ladder = kinetic energy⇒potential energy
*Starting a car = chemical energy⇒mechanical energy
*Turning on a flashlight = chemical energy⇒electrical energy
