How could the rescue workers use squeezing?
Explanation: The generator underneath the tiles will convert the squeezing energy into electrical energy that will power the flashlight.
What type of potential energy is a boulder resting at the top of a hill?
abundant potential
What are the energy transfers when walking up a flight of stairs?
Work done and energy are both measured in joules. This is because work done is equal to energy transferred. A person who has climbed to the top of a flight of stairs has transferred chemical energy stored in their muscles to the gravitational potential energy (GPE) they have when standing at the top.
Which energy store is fills up as you run down a hill?
Stored chemical energy from food is converted into kinetic energy (ke) as the person runs. As they are running uphill, the chemical energy is also converted into gravitational potential energy (gpe).
What are the 4 energy pathways?
There are four main pathways:
- mechanical work – a force moving an object through a distance.
- electrical work – charges moving due to a potential difference.
- heating – due to temperature difference caused electrically or by chemical reaction.
What are the 5 energy stores?
Stores of energy
- kinetic energy.
- internal energy.
- elastic potential energy.
- gravitational potential energy.
- electrical energy.
- magnetic energy.
What are the 4 energy transfers?
There are 4 ways energy can be transferred;
- Mechanically – By the action of a force.
- Electrically – By an electrical current.
- By radiation – By Light waves or Sound waves.
- By heating – By conduction, convection or radiation.
Where is energy stored in food?
At the most fundamental level, chemical energy is stored in food as molecular bonds. These molecular bonds represent potential energy, which is either very stable, such as in fat molecules, or very active and transitory, such as in ATP molecules.
What are the 2 main forms of energy?
After hundreds of years of observation and experimentation, science has classified energy into two main forms: kinetic energy and potential energy. In addition, potential energy takes several forms of its own.
