Vector Quantity: Impulse
Vector quantity is defined as a quantity that has both magnitude and direction. It is represented by a vector, which is a graphical representation of magnitude and direction. The following are the different examples of vector quantities:
- Displacement
- Velocity
- Acceleration
- Force
- Momentum
- Impulse
Among the given options, impulse is a vector quantity. Impulse is defined as the change in momentum of an object. It is a vector quantity because it has both magnitude and direction. It is represented by a vector whose direction is the same as the direction of the force acting on the object, and whose magnitude is equal to the product of the force and the time for which it acts.
Explanation:
Impulse is a vector quantity because it has both magnitude and direction. When a force is applied to an object, it causes a change in the object's momentum. The magnitude of the impulse is equal to the change in momentum. The direction of the impulse is the same as the direction of the force acting on the object.
For example, if a force of 10 N is applied to an object for a time of 2 seconds, the impulse is equal to:
Impulse = Force x Time = 10 N x 2 s = 20 Ns
The impulse vector has a magnitude of 20 Ns, and its direction is the same as the direction of the force applied.
Conclusion:
In conclusion, impulse is a vector quantity because it has both magnitude and direction. It is represented by a vector whose direction is the same as the direction of the force acting on the object, and whose magnitude is equal to the product of the force and the time for which it acts.
