Physics 2001 JAMB Past Questions - Question 9: Which of the following consists entirely of vector quantities?

Correct Answer

A

Explanation

Vector quantities are physical quantities that have both magnitude and direction. Here is a list of some common vector quantities:

1. **Displacement**: It is the change in the position of an object, and it has both magnitude and direction.

2. **Velocity**: Velocity is the rate of change of an object's displacement with respect to time. It has both magnitude and direction.

3. **Acceleration**: Acceleration is the rate of change of velocity with respect to time. Like velocity, it has both magnitude and direction.

4. **Force**: Force is a vector that represents a push or pull on an object. It has both magnitude and direction.

5. **Momentum**: Momentum is the product of an object's mass and its velocity. It is a vector quantity because it depends on both the mass (scalar) and velocity (vector).

6. **Torque**: Torque is a vector quantity that represents the rotational effect of a force. It has both magnitude and direction.

7. **Electric Field**: In electromagnetism, the electric field is a vector quantity that describes the force experienced by a charged particle at a point in space.

8. **Magnetic Field**: Similarly, the magnetic field is a vector quantity that describes the force experienced by a moving charged particle in a magnetic field.

So, all the quantities mentioned above consist entirely of vector quantities.
