Which force interact with a chair?
Slide 10 - Question ouverte
Force
Force is measured in Newton
Slide 11 - Diapositive
How to calculate force
Force (in Newton) = mass (in kg) x 9,81
Slide 12 - Diapositive
Why 9,81???
Everything with mass attracts each other
Slide 13 - Diapositive
The bigger the mass, the bigger the pull
Slide 14 - Diapositive
Which one has more mass, the moon or the earth?
A
moon
B
earth
Slide 15 - Quiz

A
moon
B
earth
Slide 16 - Quiz
The mass of the moon is smaller, so gravity is less
only 1,62
Slide 17 - Diapositive
How to calculate force
Force (in Newton) = mass (in kg) x 9,81
Slide 18 - Diapositive
Lets try...
Slide 19 - Diapositive
Perry has a mass of 5 kg. How many Newtons act on him?
Slide 20 - Question ouverte
Now it's your turn!
