Average Speed

Question 1

What is velocity?

Answer 1

Velocity (or speed) is a measure of how far an object traveled in a unit of time. For example: 5m/s means an object travels 50 meters in one second.

Question 2

What is average speed?

Answer 2

Average speed is the average of the speed of an object over a long stretch of time.

Question 3

What is the formula for average speed?

Answer 3

d=vt
OR
v=d/t
OR
t=d/v

Question 4

What do the three letters represent in the velocity formula?

Answer 4

v=velocity (speed)
d=distance (traveled)
t=time (taken)

Question 5

What is an experiment that could be performed to measure average speed?

Answer 5

1. Place 2 light gates on a ramp and measure the distance between them.
2. Place a trolley at the top of the ramp.
3. Release the trolley and time how long it takes to travel from the first light gate to the second.
4. Use the formula for average speed to calculate velocity
