When you are lying down, your heart does not need to work as hard against gravity. When you are standing, your heart must work to pump blood against gravity to get blood to the brain and other tissues.

Is acceleration the rate of change of the rate of change of position?
no its speed that definds the rate change of position
What is the rate of change in position called?
Rate of change in position is called velocity.
The velocity of an object is the rate of change of its position What is it?
Velocity is the rate of change of the position of an objec
Why does a persons heart rate change?
because they need a change in heart rate.
What is a good resting heart rate?
A good resting heart rate is when your heart beats good and when your heart is in a good position.
What is rate of acceleration?
The rate of change of velocity. (As velocity is the rate of change of position.)
Why is velocity the rate of change of its position?
rate of change of position is just a fancy way of saying "speed"
What is rate of change of position?
Rate of change of position = speedIf you also reveal the direction of the speed, then you have velocity.
Do rate and amplitude always change together in a frog heart?
Does the amplitude of the heart and heart rate always change together
Can a catalyst change rate of reaction equilibrium position or both?
A catalyst cannot change the equilibrium position. However, it can change its rate.
Why does the body positioning affect heart rate?
The heart rate is affected by the body activity and position for example during rest the rate will be around 60 100 beats per minutes. Also when you are lying down the hearts beats at a fewer rate than when you are standing or sitting, this is possible because the body gravity is reduced during rest allowing the heart to pump blood easily.
The rate of change in position or rate of motion?
rest
