AUT 101-CHAPTER 3 EXAM QUESTIONS AND
ANSWERS 100% PASS

1. Describe Newton's first law of motion and give an application of this law in Automotive Technology. -

✔✔Newton's first law of motion states that an object at rest tends to remain at rest and object in motion

tends to remain in motion. When a car is parked on a level street, it remains stationary unless it is driven

or pushed.


2. In what four states does matter exist? Cite examples of each. - ✔✔The four states of matter are solid,

liquid, gas and plasma. The atoms in a solid are tightly bound to each other, either in a regular geometric

lattice (crystalline solids, which include metals and ordinary ice) or irregularly (an amorphous solid such

as common window glass). A liquid, like a gas, displays the properties of a fluid. A liquid can flow,

assume the shape of a container, and, if placed in a sealed container, will distribute applied pressure

evenly to every surface in the container. Water is a good example of a liquid. Gas may be made up of

individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g.

oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide). A plasma can be

created by heating a gas or subjecting it to a strong electromagnetic field applied with a laser or

microwave generator. The sun is an example of plasma.


3. Explain Newton's second law of motion and give an example of how this law is used in automotive

theory. - ✔✔Newton's second law of motion states that when a force acts on an object, the motion of the

object, the motion of the object will change. Trucks have a greater mass than cars. Because of the large

mass requires larger force to produce a given acceleration, a truck needs a more powerful engine than a

car.


4. Describe five different forms of energy. - ✔✔Chemical, Thermal, Electrical, Mechanical and Radiant

5. Describe four different types of energy conversion. - ✔✔Chemical to Thermal, Chemical to Electrical,

Electrical to Mechanical and Thermal to Mechanical.


6. Explain why a rotating, tilted wheel moves in the direction of the tilt. - ✔✔Because the centerline of the

wheel is in the direction of the tilt the wheel will move in relation to it.


7. Why are gases and liquids considered fluids? - ✔✔Because the characteristic of fluids is that they will

conform to the shape of the container just like gases and liquids.


8. Describe how out-of-balance forces can affect the automobile. - ✔✔Improper balance can cause

premature wear or destruction of parts such as the uneven wear on tire if not correctly balanced.


9. Describe the effect of pressure on an enclosed volume of a gas. - ✔✔The pressure of a gas in a volume

increase or decrease in relationship to its temperature. Increasing the temperature of the gas will increase

its pressure.


10. The nucleus of an atom contains: - ✔✔protons and neutrons.


11. Which of the following is the correct formula used to calculate engine displacement? - ✔✔A.

Displacement=π x R2 x L x N


12. Work is calculated by multiplying: - ✔✔Force by Distance.


13. Energy may be defined as the ability to do what? - ✔✔work.


14. Name three types of simple machines. - ✔✔Inclined plane, pulleys and levels


15. When one object is moved over another object, the resistance to motion is called what? - ✔✔friction.


16. Weight is the measurement of the_________on an object. - ✔✔earth's gravitational pull


17. Torque is a force that does work with a _______ action. - ✔✔twisting
