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.
One factor that does not influence the rate of impulse propagation is the size of the neuron. The rate of impulse propagation is determined mainly by the myelination of the axon, the presence of nodes of Ranvier, and the diameter of the axon.
The presence of a refractory period caused by the locking of Na channel in the closed position. The happens just after the Na has passed through it and is not influenced by the voltage. This means that that section of the cell cant be depolarised again for a while and so the AP cant go backwardes.
The movement of electrical impulses in the heart coordinates the contraction of its chambers. The impulses initiate the contraction by stimulating the muscle cells, causing them to contract in a coordinated way. This results in the rhythmic pumping action that drives blood flow through the heart and to the rest of the body.
A nerve impulse typically starts at the dendrites of a neuron, where it receives signals from other neurons or sensory receptors. These signals are then transmitted down the axon of the neuron to the axon terminals, where they can communicate with other neurons or target cells.
Myelinated A fibers have the fastest speed of impulse propagation among nerve fibers.
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.
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.
The impulse on the colliding objects will be equal and opposite. impulse = m(vf- vi)
change in momentum
change in momentum
In the scenario, impulse is conserved if the total impulse before an interaction is equal to the total impulse after the interaction.
The product of impulse and time is equal to the change in momentum of the object. This is known as the impulse-momentum theorem, which states that the impulse experienced by an object is equal to the change in its momentum. Mathematically, it can be represented as Impulse = Change in momentum = force * time.
The magnitude of the impulse of a collision is equal to the change in momentum of the object or objects involved. It is calculated by taking the difference between the final momentum and the initial momentum of the system. The impulse can be determined using the impulse-momentum theorem, which states that the impulse is equal to the change in momentum.
No, impulse is the change in momentum of an object over a certain time interval. Momentum is a measure of how difficult it is to stop an object's motion, while impulse is the force applied to an object over time. So, impulse and momentum are related but not equal.
The impulse experienced by a body is equal to the change in its momentum. This means that when an external force is applied to an object, its momentum changes, causing the object to experience an impulse in the direction of the force applied.
yes
Yes, impulse is equal to the change in momentum of an object, which can be calculated as the mass of the object multiplied by the change in velocity. So, impulse is related to the change in velocity of an object.
