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