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

B 400

A motor’s power is calculated as the product of its velocity

and the amount of this it produces.

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?

C 300

DAILY DOUBLE

C 400

DAILY DOUBLE

Place A Wager

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

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
