It is a brief early systolic outward thrust , followed by late systolic retraction felt by the palpating finger when the LV contracts and rotates , the LV apex and the adjacent interventricular septum hits against the chest wall. It is usually felt at the 5th left intercostal space just inside the mid clavicular line , lasting less than 30% of systole and occupying less than 3 square cms area.

It is the change of rate of momentum
Impulse is the integral of force over time, it is measured in Newton-seconds. For instance a force of one Newton applied over one second will change the momentum, a force of two Newton's applied over half of a second will have a similar effect.
For rigid body collisions we take this to its limit and apply an infinite force over an infinitesimally small time. This impulse is equal to the change in momentum of the colliding objects. Because we are talking about forces here, Newton's third law applies, and the impulse on the colliding objects will be equal and opposite.
impulse = m(vf- vi)
In simple words: Impulse- A form of fast-moving electrical messages
impulse is impulse
Impulse = mv Impulse = Fmv
I bought the hat on impulse. It was just an impulse.
it is neuron impulse
Impulse often spurs inventions. Impulse is often caused by heightened desire. Impulse often catalyzes action. An impulse should be only be acted upon as a last resort. Impulse often creates unanticipated problems. Impulse can be beneficial or dangerous. His conclusions were driven by impulse rather than logical. Impulse is often associated with heightened desire. Impulse often brings about needed actions.
Impulse refers to both force and time....... Impulse=(the change in Force)*(time) OR Impulse=the change in Momentum

(^ is the triangle thing) *Impulse= F^t *Impulse=^p
Impulse-momentum theorem
The impulse on the colliding objects will be equal and opposite. impulse = m(vf- vi)
