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…
