Vocabulary
What is the meaning of this vocabulary word?
Energy
capacity for doing work
What simple machine does the following example show
Crane
A pulley system
What use does the Boom have on a crane
A crane boom is the long, telescopic arm used to lift and transport heavy objects
Which one of newton's law is demonstrated when kicking a soccer ball
the second law, the force on an object is equal to its mass times its acceleration.
What is light made of?
Light is a form of energy made from photons
What is the meaning of this vocabulary word?
Pulley
a wheel that carries a flexible rope, cord, cable, chain, or belt on its rim
What simple machine does the following example show
Wheelchair
A Wheel and axle
What use does the jib have on a crane
Jibs are secondary arms that extend off of the end of a boom. They allow the crane to have extra reach, but they often reduce the amount of weight that a crane can hoist
Which one of newton's law is demonstrated when Running
the first law, an object will not change its motion unless a force acts on it
Light will travel through some things and not others. Why?
In some materials, such as metal, the atoms absorb some of the photons so light does not pass through them
In a mechanical sense what is the meaning of this vocabulary word?
Boom
an extendable arm or mast, often equipped with hydraulic systems for vertical and horizontal movement
What simple machine does the following example show
Doorknob
A wheel and axle
what use does the Mast have on a crane
A mast or main boom is the supporting structure that is attached to the crane's base and stretches to the machine's highest height
Which one of newton's laws are demonstrated when Swimming
the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction
Define Refraction
What is the definition of this vocabulary word
Gravity
the force that attracts objects toward one another
What simple machine does the following example show
Roof
Inclined Plane
What use does the Trolley have on a crane
The trolley is the mechanism that moves the hoist along the bridge girder of a crane
Which one of newton's laws are demonstrated when shooting a basketball
n the second law, the force on an object is equal to its mass times its acceleration
Are rainbows an example of refraction yes or no?
Yes rainbows are an example of refracted light
What is the meaning of this vocabulary word?
Mast
the supporting structure that is attached to the crane's base and stretches to the machine's highest height
What simple machine does the following example show
Flag pole
A Pulley system
What use does a outrigger have on a crane
The outriggers act as supports that spread the weight of the crane over a larger area which in turn allows the crane to lift more without tipping over
Which one of newton's laws are demonstrated when riding on a roller coaster
the first law, an object will not change its motion unless a force acts on it
Why does light change direction when it refracts?
This change of direction is caused by a change in speed. For example, when light travels from air into water, it slows down, causing it to continue to travel at a different angle or direction
