Science Questions(Day 3)

Front 1

list the six simple machines and how they work.

Back 1

1.inclined plane-ramp(increases distance
2.wedge(output force at rite angle)
3.screw(increases distance)
4.levers--bar pivots around fixed point
5.weal and axle made by 2 objects rotating around a common axis(increases distance)

6.pulley(increases distance

Front 2

list 3 ways simple machines can work

Back 2

1.amount of force you exert
2.the distance in which you exert the force
2.direction of force

Front 3

what are the 3 types of levers?

Back 3

first class-change direction of input force
second class-increases force,does not change direction
third class-increases distance does not change direction of input force

Front 4

input force and out put force

Back 4

input force:amount of force you exert on a machine
output force:amount of force a machine exerts on an object

Front 5

input work and output work

Back 5

input work:input force x input distance
output work:output force x output distance

Front 6

physical and chemical properties

Back 6

physical:pure substence that can be observed without change
chemical:pure substence that describes its ability to turn into a different(used to classify substences)
