- 1. LESSON PLAN Subject : Physics Topic : Force and Motion Subtopic : Acceleration and Deceleration Form : 4B Date : 16 February 2009 Time : 1.20 pm – 2.20 pm Duration : 60 minutes Number of students : 44 students Learning outcome : At the end of the lesson, students should be able to: i. Define acceleration and deceleration and state that a=v–u. t ii. Calculate speed and velocity. iii. Calculate acceleration and deceleration. iv. Solve problems on linear motion with uniform acceleration using • v = u + at. • s = ut + ½ at2. • v2 = u2 + 2as. Prior knowledge : In form 2, students already learnt the basics of force and motion on land. They also learn about speed in learning area of dynamic. Learning material : Microsoft Power Point, exercise handouts, marker pen, white board. Attitudes and values : Thinking rationally, being cooperative, being confident and independent, hardworking, and thinking skills and high self- esteem. Scientific skills : Observing, defining operationally, measuring and using numbers, inferring, relating and communicating.
