The speed velocity of blood flow changes as blood travels through the systemic circulation. This change can be faster or slower. It is fastest where the cross-section area of the vascular bed is least, and slowest where the total cross-section area is greatest. This slow flow allows nutrient-waste exchange.

Acceleration can be defined as the rate at wich velocity?

Acceleration is observed when velocity changes with respect to time. For instance, at t0 an object may be moving with a velocity of 2. At t1, it could be moving with velocity of 4, which means that it has doubled its velocity; thus accelerating. This can also be observed in reverse, where at t0 the velocity is 4 and at t1 the velocity is 2. The object then has decelerated, or has slowed down with respect to change in time.


What happens when velocity changes?

When velocity changes, the speed and/or direction of an object's motion is altered. This can result in acceleration or deceleration, depending on the direction of the change in velocity. If the velocity increases, the object is accelerating; if the velocity decreases, the object is decelerating.


Does the speed of an object change when the speed changes?

Yes. The velocity changes when the direction of motion changes, because the definition of 'velocity' is 'speed and the direction'. If either speed or direction changes, then we say the velocity has changed. Notice that if the direction changes, then the velocity changes even if the speed doesn't. "Velocity" is not just a bigger word that you use for 'speed' when you want to sound smart. They mean different things.


What are acceleration and velocity?

'Velocity' means the rate at which position changes, and the direction in which it changes. 'Acceleration' means the rate at which velocity changes, and the direction in which it changes.


What changes a body's velocity?

A force changes a body's velocity.


How are acceleration and velocity alike and different from each other?

-- both are related to measurements of motion of objects -- acceleration is the rate at which velocity changes


What is it when velocity changes?

When velocity changes, that means that the object either moves faster, or moves slower, or moves in a different direction. Any of these changes is called "acceleration". A force is necessary to cause it.


Th rate at which velocity changes?

Velocity changes are referred to as acceleration.


An object in circular motion is constantly acceleratingtrue or false?

True. It is accelerating because the velocity constantly changes. The velocity constantly changes because the direction changes - and a velocity is made up of a magnitude, and a direction.True. It is accelerating because the velocity constantly changes. The velocity constantly changes because the direction changes - and a velocity is made up of a magnitude, and a direction.True.

Can bodies with different velocities have same acceleration?

Yes, velocity is acceleration x time. If acceleration is the same, velocity can be different as it changes with time. For example a car accelerating with constant acceleration will have a different velocity after 5 seconds than it will have at 2 seconds.


What it is called when velocity changes?

When velocity changes, it is referred to as acceleration. Acceleration is the rate at which the velocity of an object changes over time.


What is Three ways in which a cars velocity will change?

Acceleration: When a car speeds up or slows down, its velocity changes due to an acceleration in the direction of motion. Deceleration: If the car is moving in a certain direction and slows down, its velocity decreases. Change in direction: If the car turns a corner or changes its course, its velocity changes as it moves in a different direction.
