Explain the transformation that takes place when you turn on a flashlight.
What is Chemical (of the battery) to electrical (flow of electrons) to light energy (from the light) and thermal energy (the heat produced by the light)
200

What happens to the current and resistance in a series circuit when more light bulbs are added? 

Resistance increases and the current decreases

300
The energy an object has because of its motion
kinetic energy
300
Energy available for release from chemical reactions
Chemical energy
300
A coal grill converts _____ energy to _____ energy

300

How much current flows through a 16 V battery that has a resistance of 5.1 Ω?

3.14 amps

400
A pathway that allows for electrons to flow easily
circuit
400
What two variables influence an objects kinetic energy and how?
Mass and speed More mass = more kinetic energy More speed = more kinetic energy
400
A form of energy that is created by vibrating partibles that create waves that can travel through space This type of energy includes visible light, as well as radio waves, microwaves, and X rays
Electromagnetic energy
400
Through the process of photosynthesis, ________________ energy from the sun is changed to stored ________________ energy.
solar (energy from the sun) to chemical (food plants make through photosynthesis)
400

The amount of charge flowing through a cross-sectional area of a wire per unit of time is called:

current

500
State the law of conservation of energy
Energy can neither be created nor destroyed. Instead, all forms of energy can be converted or transformed into other forms.
500
What is mechanical energy and what is the equation for calculating total mechanical energy?
Mechanical energy is the energy that an object has because of its motion or position/condition. (combined potential and kinetic energy) Mechanical energy = KE + PE
