An example, of a rate of change over time is the emptying of a water tank by opening a valve at the bottom of the tank.
The rate of flow through the valve is dependent n the pressure difference through the orifice(valve), controlled by the difference in the level of the water in the tank.
As the water level drops the rate of flow drops because the pressure difference drops. The amount of time it will take to drain the tank completely can be calculated as a rate of change over time.
Note: this rate of flow can be elevated by elevating the tank, thus a valve attached to the bottom of the tank directly will have a faster rate of change but slower rate of flow than a valve attached some distance below the tank.
What else can I help you with?
Is acceleration the rate of change of the rate of change of position?
no its speed that definds the rate change of position
What equation do you use to find the rate of change?
Rate of change = amount of change in some period of time/amount of time for the change
What the difference between negative rate of change and positive rate of change?
A quantity with a negative rate of change becomes smaller as time goes on. A quantity with a positive rate of change becomes larger as time goes on.
Amount of change of one measurment in a given amount of time?
The rate of change is a measure of how one quantity changes over time. It is calculated by finding the difference in the quantity values divided by the difference in time. If the quantity is increasing, the rate of change is positive, while if it is decreasing, the rate of change is negative.
What is a variable rate of change?
It is a rate of change that is not the same at all points - in time or space.
Speed is an example of a rate What is a rate?
Rate of change of distance is called speed.Rate is defined as change with respect to time.
What is the relationship of the object's speed to its velocity?
Speed is the rate of change of distance with time. Velocity is the rate of change of displacement with time.
What is the rate of change of acceleration?
Velocity is the rate of change of position; acceleration is the rate of change of velocity; jerk is the rate of change of accelerationSee related link below for information on "Jerk"
Why do you need slope?
Slopes give you the rate of change. On a distance vs. time graph the rate of change (i.e. the slope) is the velocity. On a Velovity vs. Time graph the rate of change is the acceleration. etc.
What is the formula for calculating the rate of change of temperature over time, given a constant rate of change of 3/2kt?
The formula for calculating the rate of change of temperature over time, given a constant rate of change of 3/2kt, is dT/dt 3/2k.
What is the rate of change in position in a given point of time?
The rate of change in position at a given point in time is instantaneous speed, instantaneous velocity.
What is the rate of change in a position at a given point in time?
The rate of change in position at a given point in time is instantaneous speed, instantaneous velocity.
