Chapter 01: Basic Physics for the Respiratory Therapist
MULTIPLE CHOICE
1. Power is a measure of which of the following?
a. Mechanical energy
b. Gravitational potential energy
c. The rate at which work is being performed
d. 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
2. When effort produces a change in the position of matter:
a. work is performed.
b. It is known as a joule.
c. mechanical power is created.
d. 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 of
matter.
PTS: 1 REF: Page 8
3. 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?
a. Watt
b. Joule
c. Kilowatt
d. Kinetic energy
ANS: B

,Created By : TestsBanks
One joule is equal to the force of 1 N acting on 1 kg. A watt is equivalent to 1 J/s. A
kilowatt is simply 1000 W. Kinetic energy is energy an object possesses when it is in
motion.
PTS: 1 REF: Page 8
4. Power is expressed in which of the following units?
a. Newtons
b. Joules
c. Ohms
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
5. Four horsepower (hp) is equal to how many kilowatts (kW)?
a. 5.36
b. 2.98
c. 2984
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
6. The energy that an object possesses when it is in motion is called:
a. sound.
b. kinetic.
c. thermal.
d. potential.
ANS: B

Kinetic energy is the energy an object possesses when it stays in motion. Potential
energy is stored energy, and it exists in many forms such as thermal energy or sound
waves.
PTS: 1 REF: Page 9
7. If the velocity of an object is reduced by half, its kinetic energy will be which of the
following?
a. Reduced to one eighth
c. Reduced twofold
b. Increased twofold
d. Not changed
ANS: A
Kinetic energy =1/2 (mass of object square of velocity it is traveling, or mv2 ) or KE
=1/2 (V V). If the velocity is reduced by half, then KE =1/2 (1/2 V1/2 V), or (1/4 ) = ⅛
reduction.
PTS: 1 REF: Page 10
8. Energy that is stored in an object is called which of the following?
a. Kinetic
b. Potential
c. Chemical
d. Mechanical
ANS: B
Energy that is stored or possessed by an object because of its position is called
potential energy. Mechanical energy can be divided into either kinetic energy or
potential energy. Chemical potential energy often refers to the bonds in petroleum oils
that, if broken, can be converted to kinetic energy.
PTS: 1 REF: Page 10
9. The potential energy of a compressed spring is known as which of the following?
a. Gravitational
b. Chemical
c. Inelastic
