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.
If the motion is on a straight line and the impulse reverses the direction, the impulse will follow the same direction as the final motion.
The direction of impulse for motor neurons is away from the brain.
The impulse on the colliding objects will be equal and opposite. impulse = m(vf- vi)
It travels in one direction either afferent or efferent.
axon to dendrite
A nerve impulse travels toward the actual nucleus itself to pass information.
This means that the flow of a nerve impulse will travel only in one direction.
Two reasons. Recall impulse is the change in momentum. First the momentum is a vector. So imagine a triangle. One side is the initial momentum (with one direction), the second side is the final momentum (with a potentially different direction) and the third side is the impulse (or change in momentum). The other way to look at this is in terms of what causes the change in momentum. This is how impulse is generally described. The impulse can be defined as the average force acting on the particle multiplied by the time interval over which the force acts. This is sometimes represented as the integral of the force. As force is a vector so is the impulse caused by this force.
The wave direction indicated whether the electrical impulse from the heart is going towards or away from the ECG lead that is being studied.
The direction in which the nerve impulse travels relative to the central nervous system
The direction in which the nerve impulse travels relative to the central nervous system.
when the nerve was reversed in position, was the impulse conducted in the opposite direction
