Learning Objective
2.3 Understanding Inertia
Learning Outcomes
A student is able to:
• explain what inertia is
• relate mass to inertia
• give examples of situations involving inertia
• suggest ways to reduce the negative side effects of inertia.
Solve problems on linear motion with uniform acceleration using
v=u+at
s=ut+ 1
2at2
v2=u2+2as
Materials and Apparatus
Hacksaw blade, plasticine balls, G-clamp and stopwatch
Procedure
1. Teacher asks about the inertia to the students.
2. Then, the teacher introduce the topic of the day to the students showing a powerpoint
presentation, for around 25 minutes.
3. Students were divided into 5 groups, each group with 7 students.
4. Each group was given 0.05kg plasticine ball and they fixed it to one end of the
hacksaw blade while other end of the hacksaw blade was clamped to the leg of a table.
5. Students displaced the free end of the hacksaw blade horizontally to one side of the
table and released so that it oscillates.
6. Then, students recorded the time taken for 10 complete oscillations,t1, using a
stopwatch and they repeated the step to obtain the time for 10 complete oscillations for
the seond time,t2. The average value of t1 and t2 is calculated as t.
7. Students determine the oscillation period, T, using T = t

8. Students repeated steps 1,2and 3 using plasticine with masses 0.10kg, 0.15kg and
0.20 kg.
9. Then, the results were prented by the students to the class.
Conclusion
All the total 35 students achived the learning objective. Students are able to
explain what inertia is
• relate mass to inertia
• give examples of situations involving inertia
• suggest ways to reduce the negative side effects of inertia.

Materials
Cooking oil, talcum powder
Apparatus
Extra High Tension ( E.H.T. ) power supply ( 0 - 5kV ), electrodes with different shapes
( pointed electrode and plane electrode ), a petri dish, connecting wires
Procedure
1. Teacher ask the student what is the relationship between electric field and charge flow.
2. Teacher tells that topic of the day is analysing electric field and charge flow by
showing a powerpoint presentation.
3. Teacher divides the students into 5 groups, with 7 students ina group.
4. Each group were given the materials and apparatus.
5. Teacher set up the apparatus for each group.
6. Then the E.H.T. power supply is switched on and the voltage to 4 kV is adjusted.
7. Then, the movement of talcum powder and the field patterns was oberved by the
students.
8. Students repeat the steps 1 to 3 using the electrodes.
9. Finally every group present their result to the class.
10. Students also recall the activity carried out using a Van De Graff generator to show the
relationship between electric charge and current flow.
I – current
Q - charge
T - time
Conclusion
All the total 35 students achived the learning objective. Students are able to
State the relationship between electron flow and electric currentdefine an electric current
Describe an electric filed.
