5 Things I have learnt from the exam
and then list 5 things you have learnt!
Gravity = air resistanceTerminal speed
gravity
As the dog falls faster and air resistance increases, eventually the air resistance becomes as big as (equal to) the force of gravity.
The dog stops getting faster (accelerating) and falls at constant speed.
This velocity is called the terminal speed.
Air resistance
Falling without air resistance
gravity
The ball falls faster and faster and faster…….
It gets faster by 10 m/s every second (10 m/s2)
This number is called “g”, the acceleration due to gravity.
Stopping distances
Thinking distance is the distance traveled whilst the driver is thinking (related to the driver’s reaction time).
