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?
Why is acceleration zero with uniform velocity?
Uniform velocity means the velocity is not changing. Acceleration is defined as the rate of change of velocity. If velocity isn't changing, the rate of change is zero.
The rate at which velocity is changing is?
Acceleration is the rate at which velocity is changing. It is the first derivative of velocity with respect to time, and it measures how quickly the velocity of an object is increasing or decreasing over time.
How does acceleration and velocity differ?
Acceleration is the rate at which velocity is changing.
Velocity and acceleration related?
Acceleration is the rate at which velocity is changing, with the direction of the change.
How fast velocity is changing at a specific instant?
Acceleration is the rate of change of velocity.
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.
Which rate at which an object changing in position?
It is speed or velocity.
Why do you had to calculate acceleration with velocity?
Because acceleration is the rate of change of velocity: it is a measure of how quickly velocity is changing.
Is the rate of your velocity change your acceleration?
Yes, the rate of change of velocity is equal to acceleration. This means that if an object's velocity is changing, it is experiencing acceleration, either by speeding up, slowing down, or changing direction.
If displacement is not changing as a function of time then what can we say about velocity?
If displacement is not changing as a function of time, then velocity is zero. Velocity is the rate of change of displacement with respect to time, so if there is no change in displacement, the velocity is zero.
The rate at which velocity is changing at a given instant is described by?
The rate at which velocity is changing at a given instant is described by acceleration, which is a vector quantity that represents the rate of change of velocity with respect to time. It can be positive (speeding up), negative (slowing down), or zero (constant velocity).
What is the term describing how fast an object is changing its velocity?
This is known as acceleration (rate of change of velocity) measured in units of m/s/s or m/s2
