Mars Mission - lesson 9

• Repeat after the holiday: Big quiz
  
  
• How is the progress?  Questions?
  
  
• Continuing the mission

Name four (or more) properties of a planet 

that are needed for habitability

Surface; Atmosphere; Gravity; Temperature

further: Water present? Furtility ...

Name the planets of our solar system,
starting from nearest to the sun.

Velocity

standard unit:      

v=​Δt​​s​​

​s​​m​​

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

1. 13,9 km/h
2. 150 km/h
3. 0,5 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?

1. 112000 m/s
2. 31,1 m/s
3. 403 m/s
4. 0,112 m/s

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

1. 3,3 m/s
2. 12 km/h
3. 12 m/s
4. 43,2 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?

1. 37,5 m
2. 150 m
3. 300 m
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?

1. 4000 s
2. 250 s
3. 0,004 s
4. 0,25 h

Time

standard unit:      

Δt=​v​​s​​

s

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
2. deform
3. keep in balance
4. accelerate

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?
