Phisical Science Flashcards
Radiation
The transfer of heat through the Sun (electromagnetic waves)
Convection
The transportation of heat using a gas or a liquid
Conduction
The transportation of heat when two objects are touching
Velocity
Speed, Direction, and Objects Moving
Physical Changes
Changes that affect the form of a chemical substance
Friction
A force that occurs when two objects rub against each other and creates heat
Chemical Properties
A substance with properties that are only observable during a chemical change
Average Speed
How far an object moves in a certain amount of time
Chemical Changes
When a substance combines with another to create a new substance
Newtons Law #1
When an objects in motion, it wants to stay in motion
When an objects at rest, it wants to stay at rest
Newtons Law #2
When two forces act on an object the forces are balanced and the object doesn’t move. When the forces are unbalanced the objects move.
F = M x A Law
Newtons Law #3
For every action there is an equal and opposite reaction
Physical Properties
Objects that can be observed or measured without the changing of matter.
Force
A push or a pull on an object
