True or false, an inclined plane is not a tilted surface.
False, it is a tilted surface
True or false, all forces have only one comoponent.
FALSE
Is friction the force that makes objects lift. For example: In Harry Potter
NOOO HARRY POTTER IS MAGIC.
MECHANICAL ADVANtage yes
Is it true that in science, work is calculated by multiplying the output force in newtons.
nope, its multiplying the force applied
What is a simple machine
A simple machine is a device, composed of only one or two parts, that requires a single force to work.
Is it true that mass is the measure of how much a pulley weighs?
Falseee
Static friction is the force that prevents surfaces at rest from sliding.
How do you find the MA for measured output force and the input force??
devided output by input
it's often defined as the ability to do work
Name the 6 simple machines
Inclined plane, the wedge, the screw, the lever, the wheel and axel, the pulley
What is the common term for magnetic force
MAGNETIC PULL: MAGNETIC PUSH
Sliding friction is the force that acts against the sliding of an object. TRUE?? OR FALSE??
FALSEEEEEEEE
True or false, actual mechanical advantage is the mechanical advantage that actually occurs.
true!
What is a major source of energy on earths surface.
THE THING IN THE SKY THATS BRIGHT, the SUNNNNNNNN
True or false, a steering wheel is the only example of a wheel and axel simpel machine.
FALSEEEEEE
What is the unit we measure for force in?
NEWTONNNNSS
yess!!
Can you estimate the mechanical advantage of machines by comparing output by force distance?
NOPE, THAT'S DUMB AND WON'T WORK!!!!!!
work = what?
work = force applied (in newtons)
What are the three classes levers are divided into?
Class 1: The fulcrum is between the load force and the input force.
Class 2 levers: the load force is between the fulcrum and the input force.
Class 3 levers: The input force is between the fulcrum and the load force.
When did Isaac Newton create newtons (hint: long time ago...and I mean LONG time ago)
1687
DO METEORS LIGHT UP IN THE NIGHT SKY WHEN THEY CONTACT EARTHS ATMOSPHERE.
YES IT DOES YOUR RIGHT (or wrong, I dont know what your answer was)
true or false, Input force refers to the distance over which output force is applied.
FALSE
Is energy measured in joules? Or KJ
JOULES BUT WHEN ITS IN THOUSANDS, ITS KJ
