Average speed is calculated by dividing distance traveled by time. How is average velocity calculated?
displacement divided by time
time divided by displacement
velocity divided by acceleration
none of the above
An object on a number line moved from x = 15 cm to x = 65 cm and then moved back to x = 25 cm, all in a time of 10 seconds. What was the object's total displacement?
10 cm to the right
10 cm
90 cm
50 cm to the right
An object on a number line moved from x = 15 cm to x = 65 cm and then moved back to x = 25 cm, all in a time of 10 seconds. What was the object's average speed?
(Hint: Speed = Distance / time)
90 cm / 10 seconds = 9 cm / second
65 cm / 10 seconds = 6.5 cm / second
15 cm X 10 seconds = 150 cm / second
65 cm - 15 cm = 40 cm
An object on a number line moved from x = 15 cm to x = 65 cm and then moved back to x = 25 cm, all in a time of 10 seconds. What was the object's average velocity?
(Hint: Velocity = displacement / time)
90 cm / 10 seconds = 9 cm / second
10 cm to the right / 10 seconds = 1 cm / second to the right
10 cm to the right / 10 seconds = 1 cm / second
65 cm to the right / 10 seconds = 6.5 cm / second to the right
