True or false a point hat is 1 in from the center of a rotating wheel on a car has the same angular velocity as a point that is 2 in from the center?
True.
True or false a velocity of 50 rad per min is a linear velocity?
False.
What the rotating updraft is calledsocyclone?
false
Downward velocity is considered a negative. true or false?
Downward velocity is considered a negative. This is a true statement.
Is Acceleration is the magnitude of average velocity true or false?
False
If the object and velocity doubles the KE of an object doubles true of false?
that is false as energy is velocity squared, or 4 times
Velocity is the slope of a displacement vs time graph true or false?
False. The slope of a velocity vs time graph is acceleration
Is it true or false that Displacement is the slope of the velocity vs time graph?
It is false.
Time and velocity are both vectors.?
false
Is acceleration equal to the initial velocity minus the final velocity and then divided by time?
FALSE!
True or false as the earth rotates Miami and Seattle have the same linear velocity?
False.
Acceleration is defined as the rate change of position true or false?
Acceleration (ack-sell-uh-RAY-shun) is can be absolute, angular, and coriolis. All three are accelerations because they change position/speed over time. Velocity is a measure of distance moved over time. Acceleration is velocity that is changing (speeding up or slowing down, or changing direction) Absolute: The speed continually changes. (A car speeding up) Angular: The direction continually changes. (A planet circling the Sun in orbit) Coriolis: A combination of the above, where a particle changes its distance (absolute) to the center of a whirling mass (Angular).
