Answer :
Impulse is the area, under the force curve in a force-versus-time graph.
What is impulse?
Impulse is the integral of the force (F) over the time interval (Δt) over which the force acts. As force is a vector quantity so will be the impulse. Impulse applied on an object produces a vector change equivalent to its linear momentum, and the resulting direction is also changed. Impulse is the change in linear momentum of the body.
Two ways to calculate impulse:
- Multiply force and time (F × Δt)
- Find the change in momentum (ΔP)
Impulse is the area under the curve of a force versus time graph. The area above the time axis is positive Δp and the area below the axis is negative Δp. If the force is not constant, you can divide the graph into sections and add impulse to each section.
