Chemistry
mass divided by volume
What is density
This state of matter has the least amount of Kinetic Energy.
Solid
If net force equals zero, the forces are...
Balanced
A horizontal line on a distance versus time graph show this kind of motion.
No speed, no motion
What you change in an experiment
What is Independent Variable
Between sinking and floating, this happens to an object in water with a density less than 1 g/mL.
Floats
This state of matter contains the most Kinetic Energy.
Gas
An object in motion tends to stay in motion and an object at rest tends to stay at rest - this is which of Newton's Laws?
1st Law
An object travels 100 meters in 20 seconds. What was its speed?
5 m/s
What stays the same in an experiment
What is constant
Boiling water is an example of this type of change.
Physical change
This state of matter has definite volume, but no definite shape.
Liquid
For every action there is an equal in magnitude and opposite in direction reaction - this is which of Newton's Laws?
3rd Law
Speed tells us how fast an object is traveling. This is what velocity tells us.
Speed AND direction
What changes as a result of your independent variable. It is what you measure.
What is dependent variable
Chemical change
When energy is added to a solid, and it changes into a liquid.
Melting
The resistance an object has to change in motion.
Inertia
This occurs when an object speeds up, slows down, OR changes direction.
Acceleration
Two forms of mechanical energy.
What are potential energy and kinetic energy
This is the law of conservation of matter.
Matter is not created or destroyed, only rearranged/changed.
When energy is removed from a gas, and it changes into a liquid.
Condensing
The net force applied to a bookshelf if Tom pushes right with 20 N of Force and Sally pushes left with 25 N of Force.
5 N LEFT
Mass times velocity
Momentum
When on a swing, this is point at which you would have the most Kinetic Energy.
The lowest height
