Physics 2021 JAMB Past Questions - Question 6: Which of the following pairs gives vector quantities

Correct Answer

D

Explanation

The pairs that give vector quantities are:

1. Force and displacement
2. Velocity and acceleration
Vector quantities have both magnitude and direction. Here are some common examples of vector quantities:

1. **Force and Displacement:** Force is a vector quantity because it has both magnitude and direction. Displacement is also a vector quantity as it not only measures the change in position (magnitude) but also includes the direction of the change.

2. **Velocity and Acceleration:** Velocity is a vector quantity because it involves both speed and direction. Acceleration is also a vector quantity because it measures the rate of change of velocity with respect to time and includes direction.

3. **Momentum and Impulse:** Momentum is a vector quantity as it is the product of mass and velocity, and therefore has both magnitude and direction. Impulse is also a vector quantity as it is the product of force and time, and has both magnitude and direction.

4. **Displacement and Velocity:** Both displacement and velocity are vector quantities. Displacement is the change in position with both magnitude and direction, while velocity is the rate of change of displacement with respect to time and includes both speed and direction.

5. **Electric Force and Electric Field:** In physics, electric force is a vector quantity as it has both magnitude and direction. Electric field is also a vector quantity, representing the force experienced by a charged particle at a given point in space.

These are just a few examples, but in general, any physical quantity that has both magnitude and direction is a vector quantity.
