-9.81ms^-2
4
Q
what is N in base units
A
Kgm^-2
5
Q
define free fall
A
a state when an object only has gravity acting on it
6
Q
what shape is the trajectory when an object is in free fall with an initial velocity
A
parabola
7
Q
when throwing an object vertically how do you find time taken to reach heighest point
A
v = u+at
v = 0
8
Q
find greatest height when throwing an object vertically
A
2as = v^2 - u^2
s = (v^2-u^2)/2a
