Physics is a science subject SS2 students are required to offer in first term. The Unit of Instruction for SS2 Physics 1st Term is carefully developed from the Scheme of Work, which in turn is, based on NERDC current curriculum and SSCE syllabus.
Vectors, Moment and Equilibrium of Forces, Projectile, Simple Harmonic Motion, Simple Machines, Pressure in Fluids, Measurement of Heat Energy, Measurement of Latent Heat Energy, Practical Activities on Simple Harmonic Motion, ETC
SUB TOPICS:
A. Vectors, vector representation and addition of vectors
B. The resultant vector (Pythagoras, parallelogram and triangular laws)
C. Application of sine and cosine rules
D. Resolution of a vector
LEARNING OBJECTIVES: At the end of the lesson, learners should be able to:
1 Explain what a vector is and how it can be represented.
2 Carry out simple addition of vectors.
3 Determine the resultant force of two or more forces acting at a point.
4 ETC
Define position, distance and displacement
Position can be defined as the location of an object at a given moment in time.
Distance is a measure of an interval along a path. It is a scalar quantity. S.I. unit is metre.
Displacement is defined as the distance travelled or moved in a specific direction. It is a vector quantity. S.I. unit is metre.
See more definitions in What is Physics?
In our previous classes, we discussed fundamental quantities and derived quantities. Also, quantities in Physics can be classified into two groups, namely scalar quantities and vector quantities.
A scalar quantity is a quantity that has magnitude (size) but no direction.
A vector quantity is a quantity that has both magnitude (size) and direction.
