Which of the units that can be used to describe vector quantities?
Units that are used for measures in which the direction is relevant. Example are displacement, velocity, acceleration, force.
Which units could you use for the y-axis of a graph of speed time to display the motion of an automobile?
A time graphs units is what is used for the y-axis. This is what show the speed in time.
When is meters per second used?
When you want to describe a speed or a velocity.
What can be used to describe the location that is 9 units to the right of zero on the number line?
Absolute 9
What formula is used to find average speed?
Velocity = Distance/ TimeFor instance, if I were to travel 500 meters in 2 hours the equation would look like:V = 500m/ 2 hours. If I was asked to convert to minutes i would of course convert 2 hours to 120 minutes. So then it would look like V = 500m/ 120 minutes. 500/ 120 = 4.17 m/ min.Speed, speed is a numerical indication of motion. It is measured in speed units (m/s) per time units (s). The formula for speed:Speed = distance travelled / total time takenAverage speed = Total Distance Covered/Time Taken to Cover the Distance.The units for average speed will depend on the units used to measure the distance and the time. Commonly used measures are kilometres per hour and metres per second.Or, if you prefer to live in the past, miles per hour and feet per second.s=d/t
