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.
