NAMA PENSYARAH : PN. ANISAH BT. JAWAWI
KELAS : DKA 1A
NAMA :MOHAMAD FAREEZ BIN KELANA 04DKA13F1124 NIK MOHD HAKIMI BIN AMIN HASHIM 04DKA13F1084 MOHAMMAD NIZAL SHAHIRAN 04DKA13F1044 BIN MOHD AZRUL SHAZRIL ZULFAHMY BIN CHE SOH 04DKA13F1064 MUHAMMAD BUKHORI BIN ALIAS 04DKA13F1164
LINEAR MOTION
OBJECTIVES
1. To analyze linear motion of moving object
2. To determine displacement, velocity and acceleration of a linear motion
INFERENCE1. Linear motion is a motion along a
straight line2. Velocity is uniform when acceleration
is zero and non-uniform when acceleration is non zero
HYPOTHESIS1. Velocity is speed in a given direction 2. Acceleration is the increase of velocity
over a period of time3. Deceleration is the decrease of
velocity over a period of time
APPARATUS
TICKER TIMER
RUNWAY
POWER SUPPLY
TROLLEY
JUMPER WIRE
RULER
LAB JACK/CLAMP
PROCEDURES
Apparatus must set up as in figure 1 Inclined the runway about 1m – 2m, so
it will make trolley down freely from rest
Using cellophane tape, attach the ticker tape
Release the trolley freely and switch on the ticker timer
Figure 1
ANALYSING THE DATA
1. Mark and number every 10 dots as figure 2
2. Cut and paste ticker tape into 10-dot strips on the graph paper as figure 3

VIDEO
1 Number of 10 dots strips 8 strip
2 Total time = number of strips x 0.2 1.6 s
3 Total displacement of the trolley 1.452 m
4 Average velocity of the trolley
v= total displacement / total time
0.9075 m/s
5 Acceleration of the trolley
a. Initial velocity
u= length of first strip/ time for 10 dots
0.185 m/s
b. Final velocity
v= length of last strip/ time for 10 dots
1.575 m/s
c. Time for acceleration, t(number of strips – 1) x (time for 10 dots)
1.4 s
d. Acceleration
a= (v – u) / t
0.993 m/s
6 Average velocity
vav= (v + u) / 2
0.88 m/s
ANALYSIS
We have obtained acceleration and deceleration happens when the court track sloping. Acceleration are increasing while velocity increase
ERROR ANALYSIS
10 DOTS ON CARBONIZED TICKER TAPE IS NOT CONSTANT WHEN USING CELLOPHANE TAPE
QUESTION
Is there any difference in the value of average
velocity between Result 4 and 6? Explain your
answer.Yes. Because in Result 4 is total
displacementDivided by total time, however in Result
6 is velocity plus initial velocity and divided
by 2.
CONCLUSION
1) The hypothesis accepted.2) We must read and measure dots on
the strip carefully.3) The trolley not move if the jumper wire
at a wrong position.
ALHAMDULILLAH THE END…
