Question

Define the impulses of a force . State its dimensions and Si unit

Answer 1

Impulse is defined as the force multiplied to the time in which the force is acting on a body. Its dimensional formula is MLT to the power -1 and it's so unit is Ns(N-newton,s-second )

Answer 2

Answer:

This is the solution.

Explanation:

As per the data given in the question

We have to calculate the impulses of a force and its dimensions and Si unit.

As per the questions

we recall the concept of momentum. The property of any moving object by the virtue of its mass and motion is known as momentum. It is the product of the mass of the object and the velocity with which it is moving. If the net external force on an object is zero, then the momentum of the system is constant.

Impulse is defined as a quantity that describes the effect of force acting on an object for a particular period of time.

Mathematically, impulse is represented as the product of the force acting on the object and the time for which it is acting.

Therefore, it can be written as

J= F.Δt

When an impulse is applied to an object, then it changes the linear momentum of the vector in the same direction. The S.I. the unit of impulse is Newton Second and it is represented by the symbol (Ns).

The impulse momentum theorem is also known as the force law, which is equivalent to Newton’s second law of motion.

Dimensional Formula = [ML$T^{-1}$]

Hence, this is the solution.
