Energy, Force, & Motion

We have started our new unit and it will investigate Energy, Force, & Motion. We began by establishing that there are 7 basic forms of energy. I gave the students a nmomic to help them rember the the 7 forms of energy - CLASH'EM.
Chemical
Light (radiant)
Atomic(nuclear)
Sound
Heat(thermal)
Electric
Mechanical

All forms of energy can be grouped into two kinds, potential and kinetic. Potential energy is the stored energy of position. Kinetic energy is the energy in moving things.

Forces are the interactions between two things. A force is a push or a pull that produces or prevents motion. Friction, gravity, magnetism, and buoyancy are some examples of forces.
The students brought in small toys to use during the unit to help them better understand some of these concepts. The photos show the students using the toys to demonstrate potential and kinetic energy.
