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?
It acts on an object to displace it during work.
What is a force? A 200
When negative work is done, the force acts on an object in the opposite direction to this.
What is the object’s displacement?
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.
The horizontal component of the force.
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
A motor’s power is calculated as the product of its velocity and the amount of this it produces. B 400
What is force? B 400
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.
What is one? C 100
A ramp is an example of this kind of simple machine.
What is an inclined plane?
This simple machine is produced by wrapping a long inclined place around a shaft.
What is a screw? C 300
DAILY DOUBLE DAILY DOUBLE C 400
Simple machines can make work easier by multiplying the effort force and by changing this.
What is the direction of the force?
With regards to the amount of work done, machines can never do this.
What is reduce the amount?
Energy may be defined as the ability to do this.
What is work? D 100
Energy is equivalent to this which occurs when a force is applied to an object to displace it.
What is work? D 200
The scientific law that states Energy cannot be created or destroyed in a closed system.
The law of conservation of energy D 300
This type of energy source cannot be replaced within a lifetime.
What is nonrenewable? D 400
These are two examples of nonmechanical energy. D 500
What are: Chemical, Radiant, Electrical etc.
A lever is this type of machine.
What is Simple? E 100
A support on which a lever can pivot.
What is a fulcrum? E 200
A pry bar is an example of this class of lever.
What is a first-class lever?
A broom is an example of this class of lever
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?
The energy of motion. F 100
What is kinetic energy? F 100
Type of potential energy related to an object’s height.
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?
This is always missing from the operation of an “Ideal Machine.”
What is Friction? F 400
The class of lever in which the resistance is placed between the fulcrum and the effort force.
What is a second-class lever? F 500
