LINEAR MOTION a movement in a straight line –
Velocity = 0
1. Distance, d/ Unit: m –
length of actual path
between two points
2. Speed, v/ Unit: m s rate
-1 –
of change of distance, v =
∆𝑑
∆𝑡
3. Displacement, 𝑠 –/ Unit: m
the distance between
initial point and final point
in a straight line
4. Velocity, 𝑣/ Unit: m s
-1
(i) Average velocity, v the
av –
rate of change of
displacement,
vav = 𝑠2−𝑠1
𝑡2−𝑡1 = ∆𝑠
∆𝑡
(ii) Instantaneous velocity, v –
the instantaneous rate of
change of displacement,
v = 𝑑𝑠
𝑑𝑡
(iii) Uniform velocity,
𝑑𝑠
𝑑𝑡 = constant
5. Acceleration, 𝑎/ Unit: m s-2
(i) Average acceleration, aav –
the rate of change of
velocity, a
av = 𝑣2−𝑣1
𝑡2−𝑡1 = ∆𝑣
∆𝑡
(ii) Instantaneous acceleration,
a – the instantaneous rate
of change of velocity
a = 𝑑𝑣
𝑑𝑡 = 𝑑2𝑠
𝑑𝑡2
(iii) Deceleration negative –
acceleration (object
slowing down)
(iv) Uniform acceleration,
a = 𝑑𝑣
𝑑𝑡 = 𝑑2𝑠
𝑑𝑡2 = constant
6.
EXTRA:
(i) Total distance traveled =
how far object moved =
total path length =
distanced moved
(ii) Time taken = time elapsed
= time required = time
interval
(iii) Initial = original
(iv) Uniform = constant =
same
(v) Increasing velocity =
acceleration
(vi) Decreasing velocity (slow
down) = deceleration
(vii) Zero velocity = the object
is stationary (at rest)
(viii) Negative velocity = the
object moves in opposite
direction
(ix) Uniform velocity = zero
acceleration
(x) Negative acceleration =
deceleration (retardation)
