Physics
Twenty milliseconds is 0.020 s.
True
A fast-moving body must have a larger acceleration than a slow-moving body.
F
The velocity of the moving object is a non-zero constant
F
An aircraft approaches a runway that runs directly east as a strong wind blows out of the south. The direction that the aircraft should aim in order to land is east of north.
F
If an object's acceleration is positive, its speed must be increasing
F
The object's velocity is never negative.
F
The period of oscillation for a signal having a frequency of 60 Hz is 60 seconds
F
The slope of a distance vs. time graph is the acceleration
F
The velocity of the moving object is a non-zero constant.
F
Motion in a circle at constant speed is motion with constant velocity
False
The metric prefix that means one thousand is milli-.
False
The object's velocity is positive in region II.
False
The proper abbreviation for 'seconds' is 'sec.'
False
Uniform motion is any motion at constant speed.
False
A vector quantity has only a magnitude and no direction associated with it.
False
Motion in a circle at constant speed is motion with constant acceleration
False
The number of cycles of a periodic process that occur per unit time is called the period.
False
The terms velocity and speed have identical meanings in physics.
False
A body at the end of a spring oscillates up and down ten times in five seconds. The period of oscillation is 2 s.
T
Experimenting is part of the scientific method.
T
The acceleration of the moving object is a non-zero constant.
T
The object's velocity is zero in region II.
T
The slope of a velocity vs. time graph is the acceleration
T
An object moving in a circle undergoes centripetal acceleration
T
The maximum possible speed in nature is the speed of light.
T
The second is a metric unit of measure.
T
The time for one complete cycle of a periodic process to take place is called the period.
T
The velocity of the moving object is a non-zero constant.
T
Speed can sometimes be negative.
True
If an object's speed is constant, its velocity must also be constant.
True
If an object's velocity is constant, its speed must also be constant.
True
The proper abbreviation for 'grams' is 'g.'
True
The proper abbreviation for 'kilohertz' is 'kHz.'
True
There are one thousand megabytes in a gigabyte
