what is the velocity when acceleration is constant?
66595
Rate of change of velocity of an object is known as acceleration of that object. If acceleration is constant then it means velocity is changing ( increasing ) uniformly in equal interval of time. Thus by simple reason, velocity keeps increasing uniformly when acceleration is constant.

The horizontal velocity of a projectile is constant (a never changing in value), There is a vertical acceleration caused by gravity; its value is 9.8 m/s/s, down, The vertical velocity of a projectile changes by 9.8 m/s each second, The horizontal motion of a projectile is independent of its vertical motion.

Uniform acceleration Uniform or constant acceleration is a type of motion in which the velocity of an object changes by an equal amount in every equal time period.

From such a graph acceleration can be determined as the change in velocity divided by the change in time in a given interval. ... When you know there was a constant acceleration or a nearly constant acceleration, the average velocity will be the middle velocity between the initial velocity and the final velocity.

If a particle is moving with a uniform velocity . Then it's acceleration is Zero . Acceleration is defined as the rate of change in velocity. If the velocity is uniform, this implies that it is not changing.

Change in velocity per unit time is acceleration, so if velocity is constant, no acceleration. You can however have accelerated motion with constant speed, this is the case for object in circular orbit. But you can't have constant velocity in an accelereted motion…. ... A body moves from rest position after 5 seconds.

Terms in this set (22) Acceleration is increasing or decreasing speed or changing direction, whereas velocity is how much distance you cover in a given amount of time. What is the difference between constant velocity, instantaneous velocity and average velocity? Give an example of an object with constant acceleration.

Traveling with a constant velocity means you're going at the same speed in the same direction continuously. ... If you travel with a constant acceleration, your velocity is always changing, but it's changing by a consistent amount each second.

Acceleration is the derivative of velocity. Integrate acceleration to get velocity as a function of time. We've done this process before. We called the result the velocity-time relationship or the first equation of motion when acceleration was constant.

Acceleration is defines as the change in velocity per unit time. If object is moving with uniform velocity, its velocity is constant, that means final and initial velocity are same.. so acceleration will be 0.

To answer the second half of your question: Yes, acceleration is zero for both uniform and constant velocity based upon these two definitions. There is no difference between the two expressions. And it follows that the acceleration is zero.

The acceleration of an object is its change in velocity over an increment of time. This can mean a change in the object's speed or direction. Average acceleration is the change of velocity over a period of time. ... Constant or uniform acceleration is when the velocity changes the same amount in every equal time period.

Acceleration of a body moving with uniform velocity is ZERO. Acceleration is rate of change of speed with respect to time. ... In simple words, that means it is the rate of change of velocity. Because velocity is not changing (it is uniform) then the rate of change (acceleration) is zero.

There are two answers . If a body is in LINEAR MOTION , and if velocity is constant , acceleration is zero , because acceleration is rate of change of velocity ! ... Since it is constant , no change in velocity , no acceleration . Therefore acceleration is said to be zero .

The 'acceleration of a body' moving with uniform velocity will be zero as acceleration is defined as the “rate of change of velocity” per unit time. So if the body exhibit uniform velocity, then the rate of 'change of velocity' (dv = 0) will be zero.

There are two important types of constant motion: constant speed and constant acceleration. Constant speed means the speed does not change at all for each second of the motion. ... Constant acceleration means that the speed increases by the same constant rate for each second of the motion.

This is despite the acceleration which has been constant. We all know that acceleration is rate of change of velocity. Thus according to this definition, if the velocity of the object is zero or constant, then its acceleration will be zero.
