T/F: There is an uncertainty associated with every
measurement.
True
T/F: Accuracy refers to the repeatability of a measurement
using a given instrument.
False
All of the following are base unites of the SI system EXCEPT:
Kilogram; Kelvin; Meter; Joule; Mole
Joule
How many significant figures are there in 10,002?
5
The length and width of a rectangle are 1.125 m and 0.606 m
respectively. What is the area to the correct number of sig digs?
0.682 m^2
How many seconds in 5.24 days?
4.53 * 10^5 seconds
The density of a solid object is defined as the rations of the
mass of the object to its volume. The dimension of density is:
[M][L]^-3
, Car A is going at twice the speed of car B. They both hit the
brakes at the same time and undergo identical decelerations.
How does the time required for car A stop compare with that
for car B?
Double the time
Car A is going at twice the speed of car B. They both hit the
brakes at the same time and undergo identical decelerations.
How does the stopping distance of cars A and B compare?
Four times the distance
T/F: It is possible to have zero acceleration and still be moving.
True
T/F: When the velocity and acceleration of a moving object
have opposite signs, the speed of the object increases.
False
The slope of a line connecting 2 points on a position/time graph
gives
Average velocity
The slope of a tangent line at a given time value on a
position/time graph gives
Instantaneous velocity
If the position/time graph of an object is a vertical line, the
object is
Moving with infinite speed
When is the average velocity of an object equal to the
instantaneous velocity?
