2 Demonstrate an understanding of the difference between scalars and vectors and give common examples Add vectors by graphical representation to determine a resultantDetermine graphically the resultant of two vectors
3 For your notes Define vector and scalar quantities Give examples of eachAdd and subtract vectors
4 Scalar quantities only have magnitude (size) ScalarsScalar quantities only have magnitude (size)e.g. temperature, speed, distance, energy, mass.
5 Vectors are quantities with magnitude and direction. In pairs develop a list of vector and scalar quantitiesWhich values can be negative? What about temp?
6 Drawing vectors Well duh Use arrows Length of arrow represents magnitude of vectorDirection represents direction of vectorWell duh
7 An illustrative example Speed vs velocityConsider a car travelling in a circle at a constant speed of 2ms-1Comment in as much detail as possible onThe speedThe velocityThe acceleration
14 Summary questions Define a vector and a scalar Give 5 examples of scalar quantitiesGive 5 examples of vector quantitiesDraw a scale diagram to add a force of 3N at 30º to the horizontal to a force of 5N at 80º to the horizontalResolve an acceleration of 2ms-2 at an angle of 25º from North into two perpendicular vectors.
15 Can you? Define vector and scalar quantities Give examples of each Add and subtract vectors
