1.1 Physical quantities and measurement techniques question 3

[Maximum number: 1]

Fig. 2.1 shows a motorcyclist accelerating along a straight horizontal section of track.

Fig. 2.1

Fig. 2.1

The motorcyclist and motorcycle have a combined mass of 240 kg .

At the end of the straight section, the track remains horizontal but bends to the right, as shown in Fig. 2.1.

When the motorcyclist reaches the bend, she travels around the bend in a circular path at a constant speed.

Velocity is a vector quantity.

State how a vector quantity differs from a scalar quantity.
