What is meant by negative gradient of a quantity?
The gradient of a quantity is the greatest rate at which it changes as you move in different directions from where you are now. If the quantity has a negative gradient, that means that the quantity decreases in that direction. A great example of a negative gradient is the elevation of the land at a point on a road that has a hill on one side and a cliff on the other side. The greatest rate at which the elevation changes is in the direction off the edge of the cliff, and it's negative in that direction.
What does the slope of the curve on a velocity time graph represent?
The rate of Change in acceleration.
Is the quantity represented by x is a function that changes over time ie is not constant true or false?
True!
Which of these describes an adjustable rate mortgage?
it is subject to changes in interest rates.
Define a specific rate constant?
The specific rate constant a proportionally determined constant that is usually different for various reactions with changes in temperature.
What is vector quantity that is the rate at which velocity changes over time?
Acceleration.
What is the name of a vector quantity that is the rate at which velocity changes over time?
Acceleration vector.
What changes speed and direction?
Velocity is defined as a vector quantity representing both speed and direction. Acceleration is defined as the rate at which velocity changes. The acceleration of an object changes when it is acted upon by an unbalanced force.
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 can be defined as the rate at which velocity changes?
accelerationThe rate at which velocity changes is called "acceleration".
Can be defined as the rate at which velocity changes?
accelerationThe rate at which velocity changes is called "acceleration".
Th rate at which velocity changes?
Velocity changes are referred to as acceleration.
What is the rate velocity changes?
The rate of change in velocity is known as acceleration.
Which quantity represents rate of change of displacement?
velocity.
Is velocity based on weight?
No, velocity is by definition just a rate of movement that is a scalar quantity.
When an object's speed change does its velocity change?
Since speed is the magnitude component of the vector quantity of velocity, of course when speed changes velocity also changes. Speed is a one dimensional scalar quantity. Velocity is a three dimensional vector quantity describing both speed and direction of motion.
Compare and contrast acceleration and velocity?
-- "Speed" is the rate at which distance changes. -- "Velocity" is speed along with the direction of motion. -- "Acceleration" is the rate at which velocity changes, including the direction of the change.
