Answer questions on vectors and
1
Activity 2
What is meant by the terms physical quantity, equal vector and
negative vector?
2
Write definitions for vector quantity, scalar quantity and
resultant vector.
3
Classify the following quantities as vectors or scalars: mass,
weight, temperature,
Force F = 5 N acts to the right.
1
Draw a fully labelled scale drawing of the 5 N force using a scale of
10 mm : 1 N. (Hint: Refer to Figure 5 on page 213.)
2
Draw and label the following vectors to scale (one below the other):
4.2.1 2F (Remember F = 5 N to the right)
4.2.2 0,5F
4.2.3 -F
4.2.4 -2F
Two vectors, F, and F, act on an object. F, = 2 N upwards and F, = 2
downwards.
1 Make a tail-to-head sketch vector diagram of the forces.
2 Explain whether F, and F, are equal vectors or not.
