What is Kinetic Energy?
The nuclear process that powers the Sun.
What is nuclear fusion?
In thermal energy, particles are doing this.
What is moving faster and spreading apart?
A student pushes a box with a force of 10 N for 3 meters.
What is 30 Joules?
Energy stored in food before you eat it, in fossil fuels (coal, petroleum), and batteries.
What is Chemical Energy?
The type of energy stored in static electric charges on a playground slide.
What is electrical potential energy?
This nuclear process happens when atoms split apart.
What is nuclear fission?
Electrical energy becomes kinetic energy when this happens to charged particles.
What is they begin moving through the medium?
A machine does 200 joules of work in 10 seconds.
Calculate the power.
What is 20 watts?
Energy stored inside the nucleus of atoms.
What is nuclear energy?
Cup A: Hot water
Cup B: Cold water
Both cups have the same amount of water.
Which cup has more kinetic energy at the particle level?
What is the hot water due to thermal energy?
This is where nuclear fission commonly occurs.
What are nuclear power plants?
Electrical energy becomes potential energy when charges do this.
What is remain stored or not moving?
A 2 kg ball moves at 4 m/s.
Calculate its kinetic energy.
What is 16 Joules?
Madison works at a donut shop after school and spent some time observing the energy around her on her last shift. She told her coworker, Vicky, two statements about the mechanical energy she observed while she worked. Which types of energy are included in the mechanical energy she observed at the donut shop?
A. thermal energy from the heat in the donut fryers
B. potential energy of the donuts on the highest shelf
C. electromagnetic radiation from the lights in the donut shop
D. kinetic energy from customers chewing the pink-frosted donuts
What is B and D?
Which types of energy belong only in the potential energy category? Select two that apply.
A. chemical
B. electromagnetic
C. mechanical
D. thermal
E. nuclear
F. electrical
What is A and E?
The nuclear process that combines smaller atomic nuclei to form a larger one.
What is nuclear fusion?
Identify the particle behavior in these energy forms: (KE, PE, OR BOTH)
Thermal energy
Chemical energy
Electrical energy
What is moving particles (TE), Stored energy in bonds (CE), and Stored charges or moving charges (EE)?
A 10 kg bowling ball rolls at 2 m/s.
A 2 kg basketball rolls at 6 m/s.
Which object has more kinetic energy?
What is basketball? (36J>20J)
Explain why mechanical energy includes both potential energy and kinetic energy. Explain and provide an example?
What is Mechanical energy is the sum of potential energy (stored energy due to position) and kinetic energy (energy of motion)?
Riding a skateboard on a ramp. Going up the ramp increases your height above the ground and moving on the skateboard is the motion.
A toaster turning electricity into heat is an example of this energy transformation. (List both energy forms).
What is Electrical → Thermal energy?
Ryan told his friend Kathleen, “The sun produces energy in a process called nuclear fission. It happens under high pressure in the nucleus of the sun.”
Kathleen disagreed and said, “Nuclear fission happens in nuclear power plants, not the sun.”
Owen interjected by saying, “Nuclear fusion happens when atoms split apart, which is what happens in nuclear power plants.”
Ann dissented and said, “No, nuclear fission is when atoms split apart, which happens in the sun.”
The student who is correct.
Who is Kathleen?
DAILY DOUBLE
Billy went to dinner with his friends. It involved several examples of chemical energy. The chemical energy contained in (body cells / fuel / food / photosynthesis) changed into other energy forms during (digestion / photosynthesis / breathing / ordering). Billy ate too much and started to sweat, so his body released some
(electromagnetic / nuclear / thermal / potential) energy.
What is food, digestion, and thermal?
An object has 20 J of kinetic energy and 50 J of potential energy.
Find its total mechanical energy.
What is 70 Joules?
