Welcome to Physics lesson… FORCE AND MOTION Chapter 2 Prepared by Gayah Normahzura Bt Khaizan

Observe the animations below.. 1 2

 1 t = 0 v = 0 v = The car is…. t = 2 s t s = 0 s = 50 m

 2 t t = 0 v = 30m/s t = 3 s v = 0 The car is…. s = 0 s = 50 m

The objective of today’s lesson is: ,[object Object],[object Object],[object Object]

Previous Lesson.. ,[object Object],[object Object],[object Object],[object Object],[object Object],v = ? v = ?

Previous Lesson.. ,[object Object],[object Object],[object Object],[object Object],[object Object],v = s t v = s t

What will you learn now? ,[object Object],Definition Equation

Instruction.. ,[object Object],[object Object],[object Object],Q1 15 15 10 10 5 5 0 0 Velocity, v (m/s) Time, t (s)

v = 0 v = 15m/s Time & Velocity change Time, t increase Velocity, v increase m/s (s) 15 15 10 10 5 5 0 0 Velocity, v (m/s) Time, t (s)

Definition ,[object Object],[object Object],Equation Acceleration= change of velocity time taken for the change a = v - u t

Instruction.. ,[object Object],[object Object],Q2 0 6 2 4 4 2 6 0 Velocity, v (m/s) Time, t (s)

v = 6m/s v = 0 m/s (s) 0 6 2 4 4 2 6 0 Velocity, v (m/s) Time, t (s)

a  acceleration v u t  Final velocity  Initial velocity  Final velocity

Answer….. ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

[object Object],[object Object],[object Object]

Answer…… ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],m s -1
