MULTIPLE
CHOICE
• Power is a measure of which of the following?
• Mechanical energy
• Gravitational potential energy
• The rate at which work is being performed
• The rate at which atoms and molecules move
ANS: C
Power is a measure of the rate at which work is being performed. The formula P = W/J,
where W = watts and 1 watt is equal to 1 J/s, expresses this. Joules are the international
standard for expressing energy and work.
PTS: 1 REF: Page 8
• When effort produces a change in the position of matter:
• work is performed.
• it is known as a joule.
, • mechanical power is created.
• the law of the conservation of energy is being used.
ANS: A
Work is performed only when effort or outside forces produce a change in the position
ofmatter.
PTS: 1 REF: Page 8
• The unit used to express the force of 1 newton (N) acting on a 1-kilogram (kg) object
to move it 1 meter (m) is which of the following?
• Watt c. Kilowatt
• Joule d. Kinetic energy
ANS: B
One joule is equal to the force of 1 N acting on 1 kg. A watt is equivalent to 1 J/s. A
kilowatt issimply 1000 W. Kinetic energy is energy an object possesses when it is in
motion.
PTS: 1 REF: Page 8
• Power is expressed in which of the following units?
• Newtons c. Ohms
• Joules d. Watts
ANS: D
Power is a measure of the rate at which work is being performed. Energy and work are
measured in joules. One joule is the force of 1 N acting on a 1-kg object to move it 1
m. Ohms is the resistance an electrical circuit possesses.
PTS: 1 REF: Page 8
• Four horsepower (hp) is equal to how many kilowatts (kW)?
a. 5.36 c. 2984
b. 2.98 d. 186.5
ANS: B
1 hp = 0.746 kW.
1 hp/0.746 = 4 hp/X.
X=4 0.476 = 2.98 kW.
PTS: 1 REF: Page 8
• The energy that an object possesses when it is in motion is called:
• sound. c. thermal.
• kinetic. d. potential.
