Question

What is the impulsive force?

Answer 1

Hint: Impulse forces are forces that act for a very short period of time. The impulse is the result of the impulsive power multiplied by the time it acts. The impulsive force causes a change in momentum, which is equal to the impulse.

Complete answer:
An impulsive force is one that acts on an object for only a short time. An impulsive force is primarily produced in a collision that results in a change in the velocity or momentum of one or more of the objects involved in the collision.Impulsive forces are those that operate on a body and cause it to alter its state of motion for a short period of time rather than being sustained by non-impulsive forces.

A non-impulsive force is similar to the weight of the body, however an impulsive force is a driving body colliding with another unexpectedly. It is defined as the rate of change of momentum
$$\text{Impulse}=mv-mu$$ (momentum change)
$$\text{Impulsive force}={\displaystyle \frac{Impulse}{time}}$$

Examples:
Long Jump: When athletes land on the long jump pit, it is filled with sand to boost response time. Because impulsive force is inversely proportional to reaction time, this is done to lessen the impulsive force acting on the athlete's leg.

High Jump: A high jumper will land on a thick, soft mattress following the jump during a high jump. This increases reaction time and, as a result, the impulsive force acting on the high jumper is reduced.

Note: One inquiry may cause you to be unsure whether a force occurring on an object is normal or impulsive. Infinite forces are impulsive forces. Because infinity is not a number, we can't operate with it. However, it's a concept that can be treated with calculus.The concept of impulsive forces is useful because these forces generate a finite change in momentum in a very short time span. As a result, as time approaches zero, the ratio of change in momentum to time approaches infinity. Rather than the force itself, we might focus on the finite change in momentum before and after the application of the impulsive force (typically collision) in our study. Normal forces are forces that regulate themselves and have no upper limit on their magnitude. As a result, they are natural candidates for impulsive forces.
