Name the 2 main groups of forces
What are contact forces & forces at a distance
100
This stays the same everywhere in the universe.
What is Mass
100
The amount of force on an object due to gravity is called...
What is weight.
100
A decrease in volume produced by a force is called this.
What is compression
100
The resistance of a fluid to flow
What is viscosity
200
Force that is experienced when a wire or rope is pulled
What is tension Force
200
Mass is best measured with this instrument.
What is a balance scale.
200
Sir Issac Newton is known for finding this measuring unit of force.
What is a Newton
200
These 2 states of matter are incompressible
What are solids and liquids.
200
The speed a fluid flows from one point to another.
What is flow rate.
300
This force is spring like. Trampolines exert this force when 'throwing' you in the air.
What is Elastic
300
A balance scale you have played on.
What is a teeter totter.
300
A change in the speed or direction of an object is an example of this kind of force.
What is an unbalanced force.
300
This small unit of pressure amounts to one newton of pressure spread out over a square meter.
What is a pascal
300
Viscosity decreases in liquids when they are ...
What is cooled.
400
A force that acts on metals
What is magnetic force
400
This force pulls on objects with equal mass
What is gravity.
400
Bathroom scales don't measure weight. They measure something else.
What is force.
400
The formula for finding pressure.
What is Mass divided by volume.
400
When gasses are heated there are more of these events. As a result viscosity increases.
What are collisions.
500
Another name for this force is static electricity.
What is electrostatic force.
500
Mass is a measurement of how densely packed these are to each other.
What are particles.
500
1 kilogram of mass measures this many newtons.
What is 9.8 newtons.
500
Use a calculator! 18000 newtons of force on a spring scale that measures 6.6 meters. What pressure does the scale put on the spring below?
What is 500 pascals.
500
This refers to the strength with which the particles of an object or fluid are attracted to each other.
What is cohesion.
