What is the acceleration of an object if velocity remains constant?

velocity is the first derivative of motion, with acceleration being the second; if an object has a constant velocity, then it's acceleration is 0. This is easy to see from everyday life, when you are in a car, you only feel it jerk when you are accelerating but once you've reached your speed you feel nothing.


A car is moving at a constant speed is it accelerating?

This is one of those theoretical situations, like the frictionless surface you will see in physics problems. The short answer is that no, a car travelling at a constant speed is not accelerating. Acceleration is a change in velocity over time. Velocity is speed, so if you have zero change in velocity over a period of time, you have acceleration of zero. In the real world, you will have other factors acting on the vehicle, which would affect the acceleration.


Is time constant throughout the universe?

Time is not constant throughout the universe. It can be affected by factors such as gravity and velocity, as predicted by the theory of relativity. This means that time can pass at different rates in different regions of the universe.


Consider a particle moving with constant speed such that its acceleration of constant magnitude is always perpendicular to its velocity?

Centripetal force is a force that makes a body follow a curved path: it is always directed orthogonal to the velocity of the body, toward the instantaneous center of curvature of the path. - See more at: http://www.chacha.com/question/what-is-the-path-of-a-moving-body-whose-acceleration-is-constant-in-magnitude-at-all-times-and-is-perpendicular-to-the-velocity#sthash.pqrkWxfT.dpuf


As mass decreases kinetic energy increases?

kinetic energy of object=1/2 (mv2 ) mass of that object remains constant through out the motion so K.E. remains constant.. if some how mass decreasing then by formula we can see that the kinetic energy will also decrease.

What are decondition for an object to stay addresto keep moving constant velocity or remove constant velocity?

If the sum of all forces on an object is zero, then the object remains in constant, uniform motion. 'Constant uniform motion' means motion in a straight line at a constant speed. The physical description of such motion is "constant velocity". "Rest" is just constant velocity with a speed of zero. If the sum of all forces on an object is NOT zero, then the object's velocity must change. The change may consist of speeding up, slowing down, or turning in a different direction. Note: If you can, you should try and find the question in writing, so you can see what it's really asking.


What of the he graph of acceleration vs time for something going a constant positive velocity has characteristic?

The acceleration vs. time graph for something moving at a constant positive velocity will be a horizontal line at zero acceleration. This is because acceleration is the rate of change of velocity, and if the velocity is not changing (constant), then the acceleration is zero.


Why does the y-value of the velocity vs. time graph stay constant?

You're looking at one specific velocity/time graph that we can't see. From your description, we can tell that the object whose motion is described by that graph is moving at a constant rate of speed ... which is exactly what you just said while looking at the graph.

If the frequency is doubled then for waves what would be the wavelength and vlocity?

Frequency = Velocity divided by wavelength. So if frequency is doubled that means velocity is doubled but the wavelength is halved. You can see this by keeping wavelength a constant : If Frequency =1 and Wavelength= 1 1= Velocity/1 Velocity=1 If Frequency =2 and Wavelength= 1 2= Velocity/1 Velocity =2 OR keeping Velocity constant: If Frequency =1 and Velocity= 1 1= 1/Wavelength Wavelength =1 If Frequency =2 and Velocity= 1 2= 1/Wavelength Wavelength=1/2

What is accelerate uniformly?

It means that acceleration is constant. This meaning that velocity is varying with respect to time, we see this by this formula (v - v(initial) ) / t (Time).


What are mitered joints?

A mitered joint in where two pieces of material are each cut at 45 degree angles and put together such that they come to a point. See related link below for a picture of a mitered joint.


Is it possible to have a changing velocity and a constant speed?

Yes, the velocity of a constantly (or not constantly) accelerated object will vary. Velocity is distance per unit time with a vector. It's speed (distance per unit of time) in a given direction. Under constant acceleration, the velocity is changing at a constant rate. But the velocity is changing. It is varying. The object could be speeding up or it could be slowing down. Or it could be changing direction. Any of these change velocity. An object that is experiencing constant acceleration will have its velocity varying. Why wouldn't it have?


Which is correct-i can see on this picture or you can see at this picture or you can see in this picture?

The correct phrase is "I can see in this picture," as it refers to looking inside or within the picture itself.
