Question 1

What is impulse in physics?

Accepted Answer

ImpulseIn physics, impulse is the integral of a force, F, over the time interval, t, for which it acts. Since force is a vector quantity, impulse is also a vector quantity. Impulse applied to an object produces an equivalent vector change in its linear momentum of the object in the direction of the applied force. The SI unit for impulse is Newton-seconds (N⋅s), and its dimensionally equivalent unit is kilogram-meters per second (kg⋅m/s).Mathematically, impulse (often denoted by J or Imp) is defined as:J = ∫ F dtwhere:J is the impulse (measured in N⋅s or kg⋅m/s)F is the force (measured in Newtons, N)t is the time (measured in seconds, s)If the force is constant, the impulse can be simplified to:J = F Δtwhere Δt is the change in time.Key Concepts and Relationships:Impulse-Momentum Theorem:  This theorem states that the impulse acting on an object is equal to the change in the object's momentum.  Mathematically: J = Δp = mΔv, where p is the momentum, m is the mass, and v is the velocity.  This theorem is fundamental for understanding collisions and impacts.Variable Force:  When dealing with a non-constant force, one must use integration to calculate the impulse.  The integral represents the area under the force-time curve.Applications: Impulse is crucial in understanding phenomena such as collisions (e.g., car crashes, billiard ball impacts), impact forces, and the effectiveness of braking systems. It also explains how a small force applied over a long time can produce the same change in momentum as a large force applied over a short time.Impulsive Force: It is a large force acting for a short time. For example, the force exerted by a hammer when hitting a nail.
