What is velocity?

• Velocity is how fast an object or an person moves.
• it can present itself in km/h or m/s

What object did you use to come to school today?

Dafne Schippers ran 200m in 21.63 seconds.

what is her velocity?

Formula: Velocity= distance/ time

200/21.63= 9,25 m/s

Usain bolt ran 100m in 9,58 seconds.
What was his velocity in m/s?
Formula: Velocity= distance/ time

i want to compare dafne Schippers to my car

We have her velocity in m/s, but my car rides in km/h

how can i compare them?

fastes way to compare is:

Velocity in m/s x 3,6

9,25 x 3,6 = 33,3 km/h

What is Usain Bolt's velocity in km/h
Velocity in m/s was 10,43 m/s

1. 30,00 km/h
2. 50,53 km/h
3. 2,89 km/h
4. 37,54 km/h

Thanks for your input!
