Data la serie di misure: 320, 310, 290, 330, 340, 300, 280, 310, 330, 320, 280, 340 in chilogrammi, trovare: a) Il valore medio
b) L’errore assoluto
c) L’errore relativo
d) L’errore percentuale
e) Scrivere la misura con l’errore assoluto

v=ir = 3x15 =45 v

the closer the planet is to the sun, the larger the gravity

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
