The work done on an object is this type of
quantity because technically it has
magnitude but not a specific direction.
A 100
What is a scalar quantity?
A 100
A 200
It acts on an object to displace it during
work.
A 200
What is a force?
A 300
When negative work is done, the force acts on an object in the opposite direction to this.
A 300
What is the object’s displacement?
A 400
This force does negative work on a filled cardboard box as you try to push it
across the floor.
What is friction?
A 400
This component of the force on the object actually
does the work.
A 500
The horizontal component of the
force.
A 500
Power is the rate at which this is done.
B 100
What is work?
B 100
The unit of power.
B 200
What is a watt?
B 200
A watt is equivalent to this how many of these
per second.
B 300
What is a Joule?
B 300
B 400
A motor’s power is calculated as the product of its velocity
and the amount of this it produces.
B 400
What is force?
This scientist/inventor of a steam engine, tested a strong horse to
determine its power was 550 foot-pounds
per second.
B 500
Who was James Watt?
B 500
A simple machine is able to do work in this number of
movements.
C 100
What is one?
C 100
A ramp is an example of this kind of simple
machine.
C 200
What is an inclined plane?
C 200
This simple machine is produced by wrapping a long inclined place around a shaft.
C 300
What is a screw?

Simple machines can make work easier by multiplying
the effort force and by changing this.
C 400
What is the direction of the force?
C 400
With regards to the amount of work done, machines can
never do this.
C 500
What is reduce the amount?
C 500
Energy may be defined as the ability to do this.
D 100
What is work?
D 100
Energy is equivalent to this which occurs when a force is
applied to an object to displace it.
D 200
What is work?
D 200
The scientific law that states Energy cannot be created or
destroyed in a closed system.
D 300
The law of conservation of energy
D 300
This type of energy source cannot be replaced within a
lifetime.
D 400
What is nonrenewable?
D 400
These are two examples of nonmechanical energy.
D 500
What are: Chemical, Radiant, Electrical etc.
D 500
A lever is this type of machine.
E 100
What is Simple?
E 100
A support on which a lever can pivot.
E 200
What is a fulcrum?
E 200
A pry bar is an example of this class of lever.
E 300
What is a first-class lever?
E 300
A broom is an example of this class of lever
E 400
E 400
What is a third-class lever?
These are the two names used to describe the lever arms on
either side of a first class lever’s fulcrum.
E 500
What are the effort and resistance arms?
E 500
The energy of motion.
F 100
What is kinetic energy?
F 100
Type of potential energy related to an object’s
height.
F 200
What is gravitational potential energy?
F 200
This aspect of a “real” machine is related to the
number of times a machine multiples the effort force.
F 300
What is the Mechanical Advantage (MA) of that
machine?
F 300
This is always missing from the operation of an
“Ideal Machine.”
F 400
What is Friction?
F 400
The class of lever in which the resistance is placed
between the fulcrum and the effort force.
F 500
What is a second-class lever?
F 500
