Potential Energy vs. Kinetic Energy

a physical variable is something that

• is constant

• is measurable and can change

• does not change

• is how something looks

a unit used to measure energy

• joule

• ounce

• degree

• centimeter

Energy of motion -

• kinetic

• potential

• both kinetic and potential

• neither kinetic or potential

Energy is -

• only kinetic, not potential

• not required for change

• the ability to do work or make a change

• only potential, not kinetic

Stored energy is

• kinetic

• potential

• both kinetic and potential

• neither kinetic or potential

what do all forms of energy have in common?

• the ability to cause changes to a system

• no possibility to change

• the potential speed of an object

• only kinetic energy comes from the sun.

what variables affect the increase or decrease of energy in a system

• temperature, speed, position, pressure, and motion

• speed and distance

• pressure, motion, and speed.

• nothing because energy doesn't change

when one type of energy changes to another type of energy

• constant

• energy conservation

• energy transformation

• variable

Potential energy and kinetic energy combined are classified as -

• solar energy

• chemical energy

• wind energy

• mechanical energy.

If a student is about to release a ball and let it drop, the ball has -

• kinetic energy

• potential energy

• both potential and kinetic energy

• neither potential and kinetic energy
