Velocity

standard unit:

v = \frac{​ s ​ ​}{​ Δ t ​}

\frac{​ m ​ ​}{​ s ​}

Slide 1 - Slide

Someone is moving with 50 m/s.
What is their velocity in km/h?

180 km/h

Slide 2 - Quiz

Two units for velocity

So remember: 1 m/s is faster than 1 km/h

1 \frac{​ m ​ ​}{​ s ​} = 3, 6 \frac{​ k m ​ ​}{​ h ​}

1 \frac{​ k m ​ ​}{​ h ​} = \frac{​ 1 ​ ​}{​ 3 , 6 ​} \frac{​ m ​ ​}{​ s ​}

Slide 3 - Slide

Someone is moving with 112 km/h on the highway.
What is their velocity in m/s?

31,1 m/s

Slide 4 - Quiz

A walker has travelled 6 km in 30 minutes.
What is their velocity in m/s?

3,3 m/s

Slide 5 - Quiz

Someone is running to the trainstation with velocity 4 m/s.
It takes her/him 150 s.
How far was the distance she/he ran?

600 m

Slide 6 - Quiz

Distance

standard unit:

s = v \cdot Δ t

m

Slide 7 - Slide

Someone is running to the trainstation with 4 m/s. The station is 1000 m away.

How long will it take him/her?

250 s

Slide 8 - Quiz

Time

standard unit:

Δ t = \frac{​ s ​ ​}{​ v ​}

s

Slide 9 - Slide

Name four (or more) properties of a planet

that are needed for habitability

Slide 10 - Slide

Solid surface; Atmosphere; Gravity within range; Temperature within range

further: Water present? Furtility ...

Slide 11 - Slide

Heat transfer

What are the three ways to transfer heat?

Slide 12 - Slide

Kelvin and Celcius

? K = -273 °C

273 K = ? °C

20 °C = ? K

383 K = ? °C

1824 - 1907 1701-1744

Slide 13 - Slide

Kelvin and Celcius

0 K = -273 °C

273 K = °C

°C --> K : +273

K --> °C : -273

1824 - 1907 1701-1744

Slide 14 - Slide

What is the one mayor thing
a force does?

change speed

Slide 15 - Quiz

Forces - change velocity: How?

accelerate (make velocity bigger)
decelerate (make velocity smaller)
change direction of velocity
keep in balance (keep velocity constant)
deform, elastically
deform, plastically

Slide 16 - Slide

Questions about forces

How do you draw a force?
And what does each part of the drawing mean?

Slide 17 - Slide

In which picture is ... acceleration, deceleration, constant velocty?

Slide 18 - Slide

s-t diagram, s stands for distance
(from Latin spatio, meaning space)

Slide 19 - Slide

Questions on 1.5?

v-t diagram

v stands for
velocity

Slide 20 - Slide

Formula for pressure,
one formula, three forms:

Want to calculate pressure?

Want to calculate area?

Want to calculate force?

Tekst

P = \frac{​ F ​ ​}{​ A ​}

A = \frac{​ F ​ ​}{​ P ​}

F = P \cdot A

Slide 21 - Slide

Formula for velocity also has three forms

Look at the previous slide: The formula for pressure can be written in three forms. Find all three forms and write then on your cheat sheet!

Want to calculate velocity?

Want to calculate distance?

Want to calculate time duration?

v = \frac{​ s ​ ​}{​ Δ t ​}

s = . . .

Δ t = . . .

Slide 22 - Slide

v (m/s)

t (s)

The area under the
v-t diagram equals the travelled distance.
