Velocity

standard unit:      

v=​Δt​​s​​

​s​​m​​

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

4. 180 km/h

Two units for velocity

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

1​s​​m​​=3,6​h​​km​​

1​h​​km​​=​3,6​​1​​​s​​m​​

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

2. 31,1 m/s

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

1. 3,3 m/s

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?

4. 600 m

Distance

standard unit:      

s=v⋅Δt

m

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

How long will it take him/her?

2. 250 s

Time

standard unit:      

Δt=​v​​s​​

s

Name four (or more) properties of a planet 

that are needed for habitability

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

Heat transfer

• What are the three ways to transfer heat?
  
  

Kelvin and Celcius

                                                                          ? K = -273 °C

                                                                           273 K = ? °C

                                                                       20 °C = ? K

                                                                      383 K = ? °C

                 1824 - 1907                                                                                            1701-1744

Kelvin and Celcius

                                                                          0 K = -273 °C

                                                                           273 K = °C

                                                                         °C --> K :  +273

                                                                           K --> °C : -273

                 1824 - 1907                                                                                            1701-1744

What is the one mayor thing
a force does?

1. change speed

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

Questions about forces

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

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

(from Latin spatio, meaning space)

Want to calculate area?

Want to calculate force?

Tekst

P=​A​​F​​

A=​P​​F​​

F=P⋅A

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!

s=...

Δt=...

v (m/s)

t (s)

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