Force is a vector quantity (the direction matters) and impulse is also a vector in the same direction. When an impulse is applied to an object, it has a vector change in its linear momentum. Impulse is the product of the average net force acting on an object and its duration.J=F̅...
An impulse force is one in which the force acts over a very short period of time. An impulse can be defined as (11.36)Fˆ=∫tt+ΔtFdt≅FΔt Figure 11.23 shows an example of an impulsive force, having a magnitude F and a duration Δt. An impulsive force, such as a hammer ...
