wheel and axle
force multiplier
wheelbarrow
speed multiplier
8. When i rub my hands together, energy changes from kinetic to heat. Energy has therefore what?
transferred
converted
transformed
produced
9. Moving a door handle closer to the hinge of the door requires what?
less effort to open the door
no change in effort
more effort to open the door
impossible to open the door
10. A simple machine that allows objects to be raised with less effort than would be required to lift it straight up is a what?
wedge
lever
pulley
ramp
11. Wedges are simple machines because....
they can be used tp penetrate or split objects
they use the turning effect of a force to make a task easier
You can pull or lift a heavy load with a lot less effort
They make a persons undies go up over their heads
12. A wheelbarrow is what type of lever?
first class
second class
third class
13. what does the effect of an idler gear have on the driven gear?
makes gear turn is same direction as driving gear
makes gear turn in opposite direction of driving gear
changes vertical motion into horizontal motion
changes circular movement into upward straight line movement
14. Which example best describes a third class lever?
opening a tin can with a spoon
shoveling dirt with a spade
a see-saw
a wheelbarrow
15. Which of the following statements is true?
A kg of feathers is more dense than a kg of bricks
anything that floats in water has a density equal to or less than the density of water
buoyancy is greater in fresh water than in salt water
buoyancy is greater in air than in water
all answers are false
16. A lever that can rotate is also known as a what?
rack and pinion
wheel and axle
block and tackle
wheel and pinion
rack and tackle
axle and block
17. A definition of density would be what?
a measure of the pushing power of a fluid
the amount of volume an object has
how much matter is packed into a measured volume
how much gravity can fit into a small amount of volume
18. A multi-pulley system is also known as a what?
screw and thread
block and tackle
double pulley
double fixed pulleys
19. which of the following statments is false?
2 double pulleys require less effort to lift an object than 2 single pulleys
the effort distance increases as the load distance increases
it is much easier to use a block and tackle to lift a car engine out than to use a single pulley system
A pulley does not decrease the size of the force, or effort to lift the load, it simple changes the direction of the effort
all statements are true
20. If the driving gear is larger than the driven gear, what will happen?
the driven gear will move faster than the driving gear
both gears will spin at the same time
the driven gear will spin slower than the driving gear
the driving gear will spin in the same direction as the driven gear
21. A machine that consists of two or more simple machines is known as a what?
multi-simple machine
compound machine
complex machine
composite machine
22. A simple machine that reduces the force needed to penetrate a solid object by increasing the distance travelled is known as a what?
wedge
ramp
screw
gear
23. How much effort would be required to lift an object that weighed 450N up a vertical distance of 2m?
225N
225J
900N
900J
