Force
The cotton ball remained in the cone when you blew through the straw because ________ and ______ were balanced.
gravity and friction
A force that opposes motion between two surfaces that are touching
Friction
A form of potential energy that is stored in bonds between atoms.
Chemical Energy
Name three types of heat transfer
Convection, Conduction, Radiation
Your _____ is much less on the moon than it is on Earth. This is because the force of gravity is less on the Moon.
Weight
