what is the difference between uniform and variable velocity?

'Uniform' and 'variable' are just terms we use to describe velocities. A uniform velocity stays constant over a period of time (unchanging), while a variable velocity is one such is that changes over time.

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.

Although speed and velocity are often words used interchangeably, in physics, they are distinct concepts. Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt.

Yes, a body can have constant speed but variable velocity. For example, a body in uniform circular motion has constant speed but its velocity changes at every point during the course of motion. Whenever, the direction changes, velcoity changes.

The Brainliest Answer! the speed of a body moving with a constant velocity will not change because it is in constant speed also. Speed is the rate of change of distance and velocitygives the rate of change of displacement, i.e, its magnitude is speed as well as it has direction.

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.

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.

A variable that tells you both speed and direction of a moving object. ... The difference between velocity and speed is that velocity is the speed with a direction while speed doesn't have any directions.

The average speed is the distance (a scalar quantity) per time ratio. ... On the other hand, velocity is a vector quantity; it is direction-aware. Velocity is the rate at which the position changes. The average velocity is the displacement or position change (a vector quantity) per time ratio.

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 motion means there is no change in velocity therefore the acceleration will be 0 but uniform acceleration means there is a change in velocity if the acceleration isn't 0. ... If an object has uniform motion then it will always have 0 acceleration.

Velocity is speed in a given direction. Acceleration is change in velocity divided by time.

Answer and Explanation: The major difference between the wave velocity and particle velocity is that while propagation through the medium, the wave velocity is always constant along with the condition that density, as well as the frequency of the wave source, is constant. ... Therefore, particle velocity keeps changing.

The crucial difference between velocity and acceleration is that velocity is variation in position of the object in a particular direction in unit time. On the contrary, acceleration is variation in velocity in a certain direction per unit time.

Uniform linear motion is a motion with a constant velocity,whereas uniform circular motion is the motion with a constant speed. uniform circular motion where a centripetal acceleration always acts towards the centre and always perpendicular to the velocity of the object.

Instantaneous velocity is a continuous function of time and gives the velocity at any point in time during a particle's motion. ... Average speed is total distance traveled divided by elapsed time. The slope of a position-versus-time graph at a specific time gives instantaneous velocity at that time.

When an object is in uniform circular motion, its speed doesn't change. It means that an object will move with constant speed. Although, the speed of an object remains constant, but velocity of an object is constantly changing. The example of uniform circular motion is moon orbiting around the earth.
