For the purposes of this explanation, velocity will be given in m/s. If it's starting position is the same as its stopping position, the radio controlled car will have an average velocity of zero meters per second. This is because average velocity is displacement/time interval. Displacement is change in position and is a vector quantity, which has magnitude and direction. Average velocity is the displacement/time interval, and is also a vector quantity, including the magnitude of the speed and its direction. If you start and stop walking at the same position, your displacement is 0m, even if you walked a distance of 100 miles, and your average velocity would be 0m/s.

What does the area under the acceleration-time graph represent?
its the velocity
What is the average velocity between 12.00 and 15.00 seconds?
To find average velocity, you need to know the displacement. If you knew displacement, average velocity would be found by: V = Displacement / time
Average velocity always equals one-half the sum of the initial and final velocities?
Is this a question? or a statement that you are unsure of? Well anyways, this would be correct if acceleration was a constant but if acceleration is not a constant, the (not-constant) acceleration would change the rate of velocity and thus that statement/question would be false.
What would have a higher terminal velocity a marble or a napkin?
The marble has lower drag so its terminal velocity would be greater. Each has its own terminal velocity.
If the velocity is constant describe th slope?
The slope of a time-distance chart would be a constant. The slope of a time-velocity chart would be 0.
What would produce an average velocity of zero?
A round-trip to school and back
Select the situation below that would produce an average velocity of zero.?
A dog running in circles, stopping where it started
What situations would produce an average velocity of zero?
This would be when you travel form one point to somewhere else and then bake again while having the same velocity when you started and when you finished.
Would instantaneous velocity yield the same value as average velocity?
Only if the velocity is constant.
What is true controlled experiments produce valid data valid experiments produce controlled data controlled data produces valid experiments?
With controlled experiments it is taken into consideration what possible variables there could be and it is taken into account when conducting the experiment. This would mean that controlled experiments would produce more valid data.
What does the area under the acceleration-time graph represent?
its the velocity
When is an object's average velocity equal to its instantaneous velocity?
If the velocity is constant (i.e., there is no acceleration). Terminal velocity is an example, although any constant velocity would fit this description.
What is the magnitude of average velocity?
Not directly. acceleration is the rate at which velocity changes, but unless near light-speed the only reason velocity would cause any difference to acceleration would be due to forces which are proportional to velocity, such as drag or friction. Near the speed of light time bends so a body would, compared to the rest of the universe, appear to decelerate so as to reach a maximum velocity of the speed of light.
How long will it take for Apollo 11 to travel to the sun if it moves at the same average velocity from earth to the sun?
It would depend on what that velocity was.
How would a physicist define average velocity?
Average velocity is simply the difference in position, divided by the time. Since you use the word "velocity" rather than "speed", a direction must be indicated. Exapmle: If you drive 100 km. due North, during 2 hours, your average velocity is 50km. per hour due North.
How can you get average velocity?
You can calculate average speed by dividing the total distance travelled by the total time of travel. To go from speed to velocity, you would also need to determine the vector (direction of travel).
Compare and contrast velocity and instantaneous speed?
velocity is just a general term for speed (it could be average velocity or instantaneous velocity). Instantaneous velocity/speed (same thing) is the speed at that second. If you are familiar with calculus, it is the derivative of the position graph. Whereas average velocity is how fast the object is going in, for example, 1 hour, it is the speed that is maintained the whole hour (or the average) Instantaneous would be that at the second, at for example t=1.425, the speed is 24m/h . something along those lines
