Accept a range of answers. (e.g., do work; cause a change, hard to define)
Accept a range of answers. (e.g., position, transferred, converted, movement)
Accept a range of answers. (e.g., something wasn’t moving, then it moved; something is dropped; heat; light; sound; etc.)
Accept a range of answers. (e.g., motion to sound; motion to heat; electrical to light; electrical to heat; etc.)
Relating to motion.
Having the capacity; develop into something in the future.
Kinetic energy is energy of motion and potential energy is associated with the relative position of something.
Mass and speed.
The object’s position and its mass.
Potential energy is increased the more the spring is compressed. Once a person lets go of the spring, the potential energy is transformed to kinetic energy when the spring moves. (Students may also mention that some of the kinetic energy is converted to sound and heat.)
The speed of an object has a greater impact, because KE is proportional to ½ the mass of the object but to the speed squared.
You could move the object to greater height or distance or you could increase an object’s mass.
Energy makes stuff happen; although it is hard to define energy, we can describe how it behaves in systems and how it is manifested in phenomena. (Disciplinary Core Ideas, pg. 60)
Energy of motion.
Energy stored in an object based on its position.
Force of attraction between any two masses.
Process where energy is moved from one place to another.
Process where there is a change in energy from one form to another.
½ m X v2 (½ the mass times the velocity squared) which shows that the kinetic energy of an object is proportional to the mass and velocity of the object.
(In mathematics) having a constant ratio to another quantity.
Pattern of data that shows greater increase with passing time.
How can you know if something has energy?
Give two examples from everyday life where potential and kinetic energy is used.
When you bounce a ball eventually it will stop bouncing. Where does the energy go?
"My students loved the videos. I started the video subscription in May and used them as a review before the state test, which I know contributed to 100% of my class passing the state test."
