Lesson 10
displacement time graph
displacement will increase to maximum height then start to reduce to 0
SI unit for displacement = m
vector quantity
denoted by s
its the distance measured from a reference point to the final position of a point
velocity
vector quantity
SI unit is [m/s]
denoted by v
it is the rate of change of displacement
acceleration
SI unit is [m/s^2]
denoted by a
is the rate of change of velocity with respect to time
on a velocity-time graph
area under the graph represents displacement
gradient represents acceleration
formula for constant acceleration
v = u + at
v^2 = u^2 + 2 a(sf - si)
sf = si + ut + 1/2 at^2
