SI UNITS
What are at least 3 prefixes for units?
Kilo, Hecto, Deca, Deci, Centi, Mili
What is density?
A measure of how compact a material is; ratio of mass to volume.
What is a reference point?
A place or object used for comparison to describe the position or motion of a person or object
What is force?
A push or pull exerted on an object
The ability of something to float.
What is the SI Unit for Mass?
Grams
What is the formula to solve for density?
Density = Mass/Volume
What is average speed?
The overall rate of speed at which an object moves. Total distance over total time.
What is sliding friction?
Friction that occurs when one solid surface slides over another.
What is Bouyant force?
The upward force on an object in water.
How else can a Newton be expressed?
Kg * m/s2
What unit is density measured in?
g/ml or g/cm3
What is velocity?
Speed in a given direction
What is gravity?
The force that pulls objects towards each other
When dealing with solids, what can it's displacement tell us?
The volume of the solid.
What is the SI Unit for the volume of a solid?
What is mass?
A measure of how much matter is in an object.
What is acceleration?
The rate at which velocity changes with time
What is air resistance?
The fluid friction experienced by objects falling through the air
If a boulder's mass is greater than the mass of the water it displaces, what will it do?
Sink
What is the SI Unit for heat intensity?
Celsius
What is volume?
The amount of space that matter occupies.
What formula to find average speed?
Velocity = Distance/Time
What is a spring force?
The force of being stretched or compressed.
Changing the shape of an object can allow for a more dense material to float in a less-dense material. This is an example of what?
Archimedes Principle.
