1. distance - ANSWER ✔ The length of a path between two points
2. Displacement - ANSWER ✔ Distance and direction of an object's change in
position from the starting point.
3. position - ANSWER ✔ the location of an object
4. Speed - ANSWER ✔ The distance an object travels per unit of time
5. Acceleration - ANSWER ✔ The rate at which velocity changes
6. instantaneous speed - ANSWER ✔ the speed of an object at one instant of
time
7. Force - ANSWER ✔ A push or pull on a object
8. net force - ANSWER ✔ The combination of all forces acting on an object
,9. sound energy - ANSWER ✔ Energy caused by an object's vibrations
10.chemical energy - ANSWER ✔ Energy stored in chemical bonds
11.electric energy - ANSWER ✔ the energy that an electric current carries
12.potential energy - ANSWER ✔ stored energy
13.mechanical energy - ANSWER ✔ Mechanical energy (kinetic energy or
potential energy) is the energy of either an object in motion or the energy
that is stored in objects by their position.
14.nuclear energy - ANSWER ✔ The potential energy stored in the nucleus of
an atom. Energy released during nuclear fission ( large atoms split apart)
15.radiant energy - ANSWER ✔ energy carried by light
16.thermal energy - ANSWER ✔ Heat energy
17.Density - ANSWER ✔ mass/volume
18.atmospheric pressure - ANSWER ✔ the pressure caused by the weight of the
atmosphere
,19.Absolute Pressure - ANSWER ✔ The total pressure exerted on a system,
including atmospheric pressure.
20.laminar flow - ANSWER ✔ a smooth pattern of flow
21.turbulent flow - ANSWER ✔ Irregular flow with random variations in
pressure.
22.Static Pressure - ANSWER ✔ The force exerted by an enclosed, non-
moving fluid when pressure is applied to the fluid
23.pressure - ANSWER ✔ Pressure is defined to be the amount of force exerted
per unit area.
24.Volume - ANSWER ✔ The amount of space an object takes up
25.flow rate - ANSWER ✔ The volume of fluid that moves through a system in
a given period of time.
26.Pascal's Principle - ANSWER ✔ pressure applied to a fluid is transmitted
throughout the fluid
27.Pascal's principle equation - ANSWER ✔ F1/A1=F2/A2
28.Bernoulli's Principle - ANSWER ✔ as the velocity of a fluid increases, the
pressure exerted by the fluid decreases. (Within a horizontal flow of fluid,
, points of higher fluid speed will have less pressure than points of slower
fluid speed.)
29.Bernoulli's Equation - ANSWER ✔ P1 +1/2 ρv_1^2+ρgh_1= P_2+1/2
ρv_2^2+ρgh_2
P : absolute pressure of the fluid
v: linear speed
h: height of the fluid
30.Kinetic frictional force - ANSWER ✔ Kinetic friction occurs as bonds are
continuously formed and broken in a "stick and slip" process. This process
creates noise such as squealing tires and violin music.
31.Five functions of a machine - ANSWER ✔ 1. Change energy from one form
to another; ie wind powered generator to electrical energy
2. Transfer forces, chain on bicycle transferred applied force on pedal to
wheels of bicycle
3. Change the direction of a force, ie pushing down a lever allows you to
raise an object which is placed on the other end of lever
4. Change the magnitude of a force; ie a pulley system allows a mechanic to
remove a motor from a car while applying a small force
5. Change distance to speed; ie you can kick a soccer ball quickly by small
changes in your leg muscles
32.Acceleration due to gravity is equal to - ANSWER ✔ 9.8m/s^2
33.electric current - ANSWER ✔ The movement of electric charge from one
place to another in a period of time
