what is the difference between uniform acceleration and variable acceleration?
438621
The acceleration is said to be uniform when equal changes in velocity take place in equal intervals of time, but if the change in velocity is not the same in the same intervals of time, the acceleration is said to be variable.

Sometimes an accelerating object will change its velocity by the same amount each second. ... This is referred to as a constant acceleration since the velocity is changing by a constant amount each second. An object with a constant acceleration should not be confused with an object with a constant velocity.

Similarly, acceleration can be obtained by differentiating equation of velocity. Hence phase difference between velocity and acceleration is also pi/2. Phase difference between displacement and acceleration is pi radians or 180 degrees.

BSL Physics Glossary - uniform acceleration - definition Translation: If an object's speed (velocity) is increasing at a constant rate then we say it has uniform acceleration. The rate of acceleration is constant. If a car speeds up then slows down then speeds up it doesn't have uniform acceleration.

Uniform linear motion is motion with a constant velocity (zero acceleration) and uniform circular motion is motion with constant speed and constant centripetal acceleration (non zero).

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.

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. Thus the acceleration of the body will also be zero.

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.

Uniform linear motion is a motion with a constant velocity,whereas uniform circular motion is the motion with a constant speed. ... uniform linear motion is the motion where an object has no acceleration and is travelling with constant velocity.

Motion can be divided into uniform and non-uniform motion. A body in uniform motion covers equal distances in equal intervals of time. There is 0 acceleration in uniform motion. A body in non-uniform motion covers unequal distances in unequal intervals of time.

Uniformly accelerated motion - A body will move with a constant acceleration and its velocity will keep on changing with time at a constant/steady rate. ... Uniform Motion - A body will be moving with a constant/unchanging velocity moving in a particular direction and thus acceleration will be zero.

For uniform circular motion, for example, the speed remains constant but the direction of motion changes continuously. The acceleration vector has non-zero length and always points toward the center of the circle. Acceleration is zero only if the speed is constant and the motion is along a straight line.

either magnitude or direction or both of an object changes with respect to time. Uniform acceleration is the change of equal velocity in equal interval of time. Non uniform acceleration is the change of unequal velocity in equal interval of time. The motion of a ball rolling down.

Acceleration is the change in velocity with time. A uniform acceleration is a motion in which the change in velocity with time is linear or uniform. A non-uniform acceleration is a kind motion of motion in which the change in velocity with time is not linear or uniform.

Accepted Answer: a. Acceleration is in the direction of motion, when you are increasing the speed of the car moving along a straight line. ... Acceleration is against the direction of motion, when brakes are applied to the car in 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.

A change in v will change the magnitude of radial acceleration. This means that the centripetal acceleration is not constant, as is the case with uniform circular motion.
