Acceleration is the rate at which velocity changes. When velocity is decreasing, sometimes the word "deceleration" is used instead. Acceleration and deceleration describe generally how velocity can change. Keep in mind that things can get a little more complicated than just speeding up or slowing down. For example, in an elevator going up, you can feel increased G force resulting from acceleration upward, and you can also feel increased G force if the elevator is in free-fall and it decelerates.
Acceleration is mathematically described as:
a = dv/dt
where dv is the change in velocity over a specific period dt.
The rate at which velocity changes is either acceleration or deceleration, and it is expressed by:
a = Δv/t acceleration = change in velocity / time taken
a = F/m acceleration = resultant force / mass
However, since velocity is a vector quantity (it has both value and direction), acceleration also is a rate at which direction changes when velocity is constant
The rate of change in velocity is known as acceleration.
What else can I help you with?
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.
Can be defined as the rate at which velocity changes?
accelerationThe rate at which velocity changes is called "acceleration".
What 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.
What is a rate at which velocity changes?
Acceleration is the rate at which velocity changes over time. It can be positive (speeding up), negative (slowing down), or zero (constant velocity).
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 the realtionship between velocity and acceleration?
Acceleration is the rate at which velocity changes.
What word is the definition of the rate velocity changes with time gravity mass velocity or acceleration?
Acceleration is the word that represents the rate at which velocity changes with time. It is a vector quantity that can be caused by factors such as gravity or changes in the mass or velocity of an object.
What is defined as the rate at which velocity changes?
acceleration
Which quantity is the rate at which velocity changes?
Acceleration
What is the difference between acceleration and velocity?
Velocity is the rate at which an object changes its position, while acceleration is the rate at which the velocity of an object changes. In other words, velocity is the speed and direction of motion, whereas acceleration is the change in speed or direction of motion.
