• 1. To analyze linear motion of moving object 2. To determine displacement, velocity and acceleration of a linear motion
• Slide 3
• 1. Linear motion is a motion along a straight line 2. Velocity is uniform when acceleration is zero and non-uniform when acceleration is non zero
• Slide 4
• 1. Velocity is speed in a given direction 2. Acceleration is the increase of velocity over a period of time 3. Deceleration is the decrease of velocity over a period of time

• 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
• Slide 14
• Figure 1
• Slide 15
• 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
• Slide 16
• Figure 3

• 1Number of 10 dots strips 8 strip 2Total time = number of strips x 0.2 1.6 s 3Total displacement of the trolley 1.452 m 4Average velocity of the trolley v= total displacement / total time 0.9075 m/s 5Acceleration 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 6Average velocity v av = (v + u) / 2 0.88 m/s
• Slide 19
• We have obtained acceleration and deceleration happens when the court track sloping. Acceleration are increasing while velocity increase
• Slide 20
• 10 DOTS ON CARBONIZED TICKER TAPE IS NOT CONSTANT WHEN USING CELLOPHANE TAPE
• Slide 21
• 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 displacement Divided by total time, however in Result 6 is velocity plus initial velocity and divided by 2.
• Slide 22
• 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.
