Newton's First Law

"When the resulting force is equal to 0, an object moves with a constant speed or is standing stil
and vice verse. "

Can you use Newton's first Law to explain why the camera began moving without an astronaut putting a direct force on it?

Slide 9 - Open vraag

Slide 10 - Link

Constant Speed

As long as the resulting force is equal to 0 then the speed will remain the same: 21,4 m/s

When you are cycling the muscle force is equal to the resistance. When this occurs the forces are in equilibrium.

Slide 11 - Tekstslide

Motion
Last year, you studied motion. 
Key concepts were distance, time and velocity.
There was some talk about acceleration.
You also learned this equation:      
vave=ts

Slide 12 - Tekstslide

Acceleration

When there is a resulting force on an object the object will accelerate, decelerate or change direction. 

You can see that the velocity wil keep increasing as result when a person uses more muscle force. 
When he stops excerting this force only the friction remains and the object will slow down.
