SPEED

If you move 50 meters in 10 seconds, what is your speed?

• 5

• 5m/sec.

• 10

• 10m/sec

If a car travels 400m in 20 seconds how fast is it going?

• 20m/sec.

• 10m/sec.

• 30m/sec.

• 40m/sec.

Speed is...

• how fast an object is moving

• how far the object has moved

• how long it took the object to travel the distance

• 10 m/s 

• 5 m/s 

•  2 m/s

•  20 m/s

If Sally is speeding through the parking lot at 18m/hr, and she travels 9 m, how long did it take her?

• 2 m/hr

• 0.5 hr

• 2 m

• 0.5 m

a fixed place or an object used to determine the position of an object.

• reference point

• speed

• distance

• movement

speed =

• speed x time

• distance ➗ time

• mass x velocity

• distance ➗ speed

Which is correct?

• speed = distance x time
• speed = speed divided time
• speed = Distance divide time
• Speed = time x speed

• 20km/hr

What two measurements are necessary for calculating speed?

• Mass and time
• Temperature and mass
• Mass and distance
• Distance and time
