A particle moving with a constant velocity has no acceleration. Acceleration is the change in velocity over time. If the velocity is constant, there can be no acceleration. For you Calculus junkies, dv/dt (v is velocity) is acceleration, and will equal zero if v is a constant.

∙ 14y agoThe acceleration of an object at any particular time is known as its instantaneous acceleration. If acceleration is a function of time -- that is, if a varies with time, t-- then the evaluation of a at a particular time, tp, is the instantaneous acceleration at t = tp. Let's say acceleration is given by the linear equation a(t) = 10t - 5. When t = 1, a = 5 because a(1) = 10 * 1 - 5 = 5. It is equal to exactly 5 only when t is exactly 1. The acceleration is something less than 5 when t < 1, and it is greater than 5 when t > 1. We say the instantaneous value of a is 5 at t = 1.

∙ 8y agoWhen a particle is moving in uniform circular motion , its speed is constant . Velocity of particle changes from point to point due to change of direction of particle in uniform circular motion. This change in velocity vector leads to an acceleration which acts towards the center of circular path. The acceleration is known as Centripetal acceleration.

∙ 8y agoSince the direction changes, the velocity changes - and therefore there is an acceleration.
The acceleration is towards the center - therefore the acceleration changes all the time (since its direction changes). The magnitude can be calculated by:a = v^2 / r
or:
a = omega^2 x r
Where "^" stands for power, v for velocity, r for radius, omega for angular velocity (in radians/second).

What in the second law of motion is Mass X Acceleration the ability to apply change in veloity of the given object?
The ability to change velocity is acceleration; acceleration is dv/dt. Save
If an object is accelerating what equation relates the acceleration of that object the initial velocity and the final velocity and time?
Vf = Vi + at Where Vf = final velocity Vi = initial velocity a = acceleration t = time
How do you find the uniform acceleration if the speed and acceleration are given?
Find out the time using speed and acceleration, (time=speed/acceleration) and then use it to find out uniform velocity. From that find out uniform acceleration. (as uniform acceleration is equal changes of velocity over equal intervals of time)
What graph are used to analyze the motionof an accelerating objects?
On a accelerating body, Velocity and distance of an object are effected. For a graph plotted with Acceleration to Time, it directly gives the acceleration at any given instant. For a graph plotted with Velocity versus Time. The Slope at any instant would give the Acceleration. Or given the time frame, say A to B. Acceleration can be found out by subtracting velocity at A from velocity at B divided by the time frame A to B.
Can a body have acceleration without velocity?
Yes. Velocity is speed per unit of time with a direction vector telling you which way the object in question is moving. Acceleration is a change in velocity - in any part of velocity. If something like, say, a rock is in deep space (a zillion light years from anything) and it's moving along unaffected by any gravity or other forces, it has some velocity (some speed in a given direction, or is moving at some distance per unit of time in a given direction), but it isn't changing speed or direction. If something is moving without changing its speed or its direction (either of which requires a force to act on the object - to accelerate the object), it has zero acceleration. Such an object is said to have a constant velocity and will have zero acceleration. Certainly if an object is not moving, it has zero velocity and zero acceleration, but that's probably not what is being asked. It has velocity (zero) and no acceleration. To recap, an object can have a non-zero velocity and zero acceleration.
What is the formula used to find distance?
The distance travelled by an object in a given time is given by:Distance = Speed * TimeAlternatively for an object that is accelerating:Distance = (Speed of object before acceleration is applied * Time) + (0.5 * Acceleration * Time squared)If the object is accelerating from speed zero, the first set of brackets is irrelevant.Also, if the object is falling to the ground, acceleration = 9.81
The change in an object's velocity in given period of time?
acceleration or decceleration...
What's the difference between instantaneous velocity and instantaneous acceleration?
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
Three things that can be acceleration?
Only one thing can be acceleration; the changing velocity of any given object. That's what acceleration is. Acceleration is caused by a net force on the object.
How do you get the acceleration of an object?
Acceleration= Distance divided by time
When does an object's acceleration change?
Acceleration is change of velocity / time.
Can an object have zero acceleration and eventually-reverses its acceleration?
I am not sure what you mean by reversing a zero acceleration. An object's acceleration can, of course, change over time.
How can you calculate the acceleration of an object moving in a straight line by?
It really depends what information you are given. In the simplest case, you use the definition of acceleration as delta(speed) / time. That is, you divide the change (delta) in speed, and divide by how long it takes for this change in speed. This gives you the average acceleration over the given time. If you assume a constant acceleration, it is also the instantaneous acceleration at any moment.
When the acceleration of an object is zero what is the velocity at the same time?
As long as acceleration is zero, the object's velocity is constant.
What is the formula in finding the acceleration of an object?
acceleration = change in velocity / time
The equation used to find acceleration is?
There are several different equations that can be used to find acceleration. The right one to choose depends on what information is given or measured. Examples: -- You're given the mass of an object and the force acting on it. Acceleration = (force) divided by (mass) -- You're given the starting and ending speed of a car, and how much time it was moving. Average acceleration = (change in speed) divided by (time for the change) -- An object started out from rest. You're told how far it moved and how long it took. Average acceleration = (2 x distance) divided by (time squared)
An increase of speed during a given interval of time is called?
The shift of velocity per unit of given time is called acceleration. The types of acceleration are negative acceleration and positive acceleration.
