Kinematics

A quantity that has a magnitude and a direction is called a

• scalar quantity

• vector quantity

60 km/h represents a .......

• Distance

• Displacement

• Speed

• Velocity

• Acceleration

Answer explanation

60 km/h is a speed and not a velocity as no direction was given.

60 km/h North represents a

• Distance

• Displacement

• Speed

• Velocity

• Acceleration

2 m left represents a

• Distance

• Displacement

• Speed

• Velocity

• Acceleration

Answer explanation

m stands for metres so it must be a distance or displacement.

left is a direction, so it is a vector quantity.

The vector quantity for distance is called displacement.

• Displacement

• Velocity

• Acceleration (scalar)

• Acceleration (vector)

v represents

• distance

• displacement

• speed

• velocity

• acceleration

2 ms^-1 up represents
