AS/A Physics | Vectors | lesson plan

# Schedule

Aug 24- Sept13 (3 weeks)

# Content

- Scalars and vectors.
- Why vectors?
- Vector operations
- resolution of vectors
- vectors in the cartesian co-ordinate system

# Instructional objectives

Students should be able to:

- Differentiate between scalar and vector quantities
- Understand that vectors have both a magnitude and direction
- understand how vectors add up.
- understand why vectors are useful in physics
- know how to subtract vectors
- know how to multiply vectors by a scalar
- know how to find the dot product of two vectors
- know how to find the cross product of two vectors
- know how to resolve vectors into components that are convenient to analyze
- know how to represent vectors in the cartesian co-ordinate system
- know how the dot product and cross product can be found using cartesian vectors

# Teaching Process

Some of the concepts are already familiar to the students. After revising these concepts, they are extended to the caresian co-ordinate system. They also learn concepts of vector multiplication

# Activities

- Gravesand's apparatus of resolving forces to show the parallelogram law of adding vectors

# Suggested reading / References

- Fundamentals of Physics -Resnick/Halliday ch?

# Assignments / Evaluation

- assignments on vector operations
- assignments on cartesian vectors
- written test
