Scalars and vectors

CIE-style questions assess classification, scaled representation, resultants, components, equilibrium and two-dimensional motion.

Objective question 1

Which pair contains one scalar followed by one vector?

Objective question 2

What is the magnitude of the resultant of 9 N east and 12 N north?

Objective question 3

A vector V acts at angle θ above horizontal. Its vertical component is:

Objective question 4

For translational equilibrium:

Objective question 5

Velocity of A relative to B is:

Structured question 1

A 40 N force acts at 30° above horizontal. Calculate its horizontal component.

Structured question 2

A displacement has components 8.0 m east and 6.0 m south. Calculate its magnitude.

Structured question 3

A 5.0 m s⁻¹ northward velocity combines with a 12 m s⁻¹ eastward velocity. Calculate the resultant speed.
