Mixtures
and Solutions
and Solutions
A substance containing two or more elements
What is a mixture?
The distance that something travels in a specific amount of time
What is speed?
Rotation around a fixed point, following a circular path or orbit.
What is rotational motion?
The ability of something to float in a liquid
What is buoyancy?
The tendency of an object to resist a change in motion or rest.
What is inertia?
A mixture in which all of the substances are evenly distributed through the mixture
What is a homogenous mixture (or solution)?
A measurement of how fast something moves in a particular direction - it has both a speed and a direction.
What is velocity?
Motion of an object in a circle without the presence of a fixed axis
What is circular motion?
The two things buoyancy depends on
What are density and displacement?
Friction
What is a contact force that slows or stops motion?
A mixture in which the substances are not evenly distributed
What is a heterogenous mixture?
The rate at which velocity changes
What is acceleration?
What is the meaning of centripetal force?
What determines an object's ability to float on a gas?
What is its density?
What is drag or resistance?
A type of heterogenous mixture, such as milk, in which tiny particles of liquid are suspended in water
What is a colloid?
How much mass an object has in relation to its velocity
What is momentum?
Centripetal force
What is a force that pushes or pulls an object toward the point about which it is rotating?
What is thrust?
A force which pushes air very quickly over a plane's wings?
An object in motion will stay in motion unless a force acts on it, and an object at rest will stay at rest unless a force acts upon it.
What is Newton's First Law of Motion?
The physical processes that can separate mixtures into their component parts
What are filtration, evaporation, and distillation?
The bigger the force acting upon an object, the faster it will accelerate. The lighter an object is, the greater the acceleration.
What is Newton's second law of motion?
An invisible force that supplies the centripetal force pulling satellites towards the object they are orbitting.
What is gravity?
An upward force that depends upon carefully-designed wings
What is lift?
The reason your body continues to sway forward when a bus you are on comes to a hard stop
What is inertia?
