A change in velocity is an acceleration. Since velocity includes speed and direction, a change in either of them is an acceleration.

An object travelling in a circle at a constant speed is accelerating continuously although the speed is constant. The acceleration towards the centre is equal to v-squared / r where v is the speed and r is the radius of curvature. This formula also applies to a momentary deviation on a curved path.

The formula comes from Isaac newton which he discovered by using the newly developed mathematical technique of differential calculus.

Since velocity is a vector, a change in direction at constant speed can be represented as a vector at right-angles to the velocity.

The factor that has the greatest effect on kinetic energy is?

The velocity of the object. Kinetic energy is directly proportional to an object's mass and the square of its velocity. Therefore, changes in velocity have a larger impact on kinetic energy compared to changes in mass.


What is the other factor that changes velocity over time?

Acceleration is the other factor that causes changes in velocity over time. When an object experiences acceleration, its velocity will either increase or decrease depending on the direction of the acceleration.


What changes the velocity of the object?

The velocity of object always changes with wanted or unwanted outer forces.


WHAT CHANGES AS THE MOMENTUM OF AN OBJECT CHANGES?

velocity


What happens when velocity changes?

When velocity changes, the speed and/or direction of an object's motion is altered. This can result in acceleration or deceleration, depending on the direction of the change in velocity. If the velocity increases, the object is accelerating; if the velocity decreases, the object is decelerating.


Is acceleration how quickly an object's velocity changes?

Yes, acceleration is the how the velocity changes. This also includes when an object turns


When an object is accelerating if its?

An object accelerates if its velocity changes. More precisely, "acceleration" is the rate of change of velocity (how quickly velocity changes), or in symbols, dv/dt.


What happens to a velocity when the acceleration changes?

If the acceleration changes, the velocity of an object will also change. If the acceleration increases, the velocity will increase. If the acceleration decreases, the velocity will decrease. The velocity and acceleration of an object are directly related.


What happens to an object's velocity when it accelerates?

"Acceleration" implies that the velocity changes.


Is the rate at which an object changes velocity?

No, velocity is the instantaneous speed of an object, the rate of change would be the acceleration of the object.


Which of these changes as the momentum of an object changes?

Momentum is defined as mass times velocity, so if the velocity changes, the momentum would naturally also change.


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.
