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

# Assignments / Evaluation

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