Yes, plus the direction that it's changing in.
Acceleration is the rate of change of velocity.
The rate of change of velocity is known as acceleration. This can come in different forms (linear / nonlinear acceleration, angular acceleration ect).
The rate at which velocity is changing at a specific instant is called acceleration. It measures how quickly an object's velocity is changing, either by speeding up (positive acceleration) or slowing down (negative acceleration). It is the second derivative of an object's position with respect to time.
If an object's acceleration is zero at a specific instant in time, its velocity can either be zero or a constant non-zero value at that instant. This means that the object could be either at rest or moving with a constant velocity at that particular moment.
Instantaneous acceleration is the rate at which an object's velocity is changing at a particular instant in time. It can be positive (speeding up), negative (slowing down), or zero (constant velocity). It is calculated as the derivative of velocity with respect to time.
Yes, instantaneous acceleration is the rate at which an object's velocity is changing at a specific moment in time. It gives information about how quickly the object is speeding up or slowing down at that exact instant.
Instantaneous acceleration is the rate of change of velocity at a specific moment in time. It indicates how quickly the velocity of an object is changing at that instant. It is typically calculated as the derivative of velocity with respect to time.
IF it changes to the completely opposite direction ... does a 180 or a "U-turn" ...then the velocity must be zero at that instant. But if the direction only changesby turning a corner or going around a bend, then there's no way to know whatthe velocity is without a lot more information.
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).
Instantaneous velocity is the rate at which an object is moving in a uniform direction, distance per unit time, at any given instant in time. instantaneous acceleration is the rate at which an object's velocity is changing at any given instant in time
Acceleration never depends on the instantaneous velocity.Acceleration is the rate at which velocity is changing, and the direction of the change.A car leaving a STOP sign at a neighborhood intersection, and the Space Shuttle in theprocess of a delicate orbital maneuver to link up with the International Space Station,could very well have the same acceleration.
No, if an object has zero acceleration, its velocity cannot be changing. If the velocity is nonzero, it must either be increasing or decreasing, which requires acceleration.
