Energy and Change: the basic five laws Law # 1. “An unbalanced force acting on a body results in a change in motion”. What this means: the balancing scales will not move…until…we do what??? Apply a weight (an unbalanced force!)
Energy and Change: the basic five laws Law # 2: Objects remain stationary or in constant motion under the influence of balanced forces What this means: The wheel will continue to spin and spin and spin…until…what??? We unbalance it (here, with brakes). Note that, once it stops, the wheel is once again in balance.

Unformatted text preview: Law # 4: Transfers of energy can vary according to the medium in which it travels. What this means: When you put a pencil into a glass of water…what happens? Thanks to the refracting property of water, the pencil appears to be bent! Energy and Change: the basic five laws Law # 5: Energy is conserved when it is transferred or transformed What this means: When you turn on a bulb, you get energy in the form of light, but you get what other form of energy as well? Stumped? Then, do the experiment with your teacher!

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
