energy

this photo has a picture of a soccer ball in the air with a lot of gravatational potential energy.

Imagine that you can travel back in time and talk to yourself about one of the concepts below. What would you tell yourself about the concepts that who make it easier to learn.



if i could go back in time to explain something to myself, i would explain the concept of constant versus conesrved. i would tell myself that constant means that the energy stays the same amount, but its in a different or the same form. conserved means that the endergy may change and be either more or less, but you can account for it. gravatational potential enegy is when you have a lot of potential for falling, like a ball perched atop a cliff has a lot of gravatational potential enregy. kinetic energy is when you are moving, or like accelartaion and speed, like a runner running on a track.internal energy is heat, or energy inside of an object.


+ What experiment was helpful/might be helpful in constructing this concept.\

think of bar charts- when you have a bar chart that has the same amount of enegy both ways, but the forms are different, its constant.
if the forces are different and some is gone, make sure there is some work done so you can account for that energy.

Doing/ calculating work

if i could go back in time and talk to myself about doing and calculating work i would tell myself that doing work is just moving something or applying a force to the system to make it move or to make the system do what the system is supposed to. i would also tell myself that calculating work is just like algebra. i would say that we use the formula W= FD, and that the work equals force times the displacement. i would also tell myself that if i am given a mass, i can use another formula to find the force to make the equation work.

the experiment that was helpful in understanding these concepts for me were mostly just the homework. going over the homework in class really helped me to understand how to use the formulas.

the picture of a cartoon lifting a weight also applies to the calculating. to calculate the amount of work being done, you would find out how much it weights, and then you could find how much work is being done in joules.
