A change in impulse equals a change in momentum. However, Impulse is the product of force and time, as is momentum, so they are not exactly the same thing.

Where does a nerve impulse start?
A nerve impulse starts at the dendrite
What is the direction of impulse for motor neurons?
The direction of impulse for motor neurons is away from the brain.
How does movement of electrical impulse relate to the contraction of the chambers of the heart?
The impulse shocks the left and right atria of the heart. This pumps blood into the left and right ventricle. The ventricles then receive the impulse and pump the blood. The movement of the electrical impulse allows the blood to move through multiple areas of the heart with only one impulse.
The duration of a nerve impulse is approximately?
A nerve impulse is approximately 1 millisecond.
Which of the following does not factor into the rate of impulse propagation?
Whether or not the impulse begins in the CNS influences the time necessary for a nerve impulse to be transmitted.
Why is it incorrect to say that impulse equals momentum?
Impulse is the change in momentum. Therefore Impulse is only equal to momentum if the initial momentum was equal to zero. Its the same phenomenon as position and displacement. Impulse= final momentum-initial momentum= mv - mv_0= Force * Time Where m is the mass and v is the velocity.
What is a direction of impulse?
impulse is equal to force which is acting on the body and ti me in small interval which is equal to momentum.so impulse is equal to change in momentum and direction of impulse is consider the direction of force and change in momentum.
What is direction of impulse?
The impulse on the colliding objects will be equal and opposite. impulse = m(vf- vi)
According to impulse - momentum theorem what does impulse equal?
change in momentum
According to the Impulse-Momentum Theorem what does impulse equal?
change in momentum
When two forces are equal do you say they are magnetic?
No, you do not.You say they are equal; there is no other technically correct word or term.
Is impulse equal to velocity multiplied by time?
yes
How is impulse relative to momentum?
impulse (force x time) is equal to momentum (mass x velocity); Ft=mv
Can a nerve impulse occur if the excitatory and inhibitory effects are equal?
no
What does the amount of force times the time applied equal?
impulse
Is impulse delivered to an object equal to a change in the objects velocity?
yes
Is equal to an impulse of 18 units?
force= 0.1, time= 18
