    • What is uniform velocity?

    A particle is said to move with uniform velocity if it moves in a fixed direction and covers equal displacements in equal time intervals, no matter how small these time intervals are.

    • How do you define it and what are its examples?

    For example, an object moving at 10 km h-1 towards the north.

    A body is said to have uniform velocity if it covers equivalent detachment in equivalent time intervals in an exacting direction, even if the time intervals are small.

    As a result, the velocity with which the same number of space units are described in each successive unit of time. The rate of change of an object’s position with respect to a frame of reference and time is defined as its velocity.

    Because velocity is a vector quantity, we must define it in terms of both magnitude (speed) and direction. A meter per second is the SI unit body considered accelerating when the magnitude or direction of its velocity changes.

    It is defined as the condition in which a body travels the same distance in the same amount of time. In equation(d = v t), v is the average velocity of a body over time t. If the magnitude and direction of the force do not change over time, the body is said to be moving at a stable velocity.

    The Earth’s rotational motion is an example of uniform velocity, i.e., when a body moves with increasing velocity at equal intervals.

    If a body travels the same distance in the same amount of time in the same direction, its velocity is uniform, no matter how small the intervals.

    Uniform velocity occurs when the velocity magnitude increases at equal intervals, whereas constant velocity occurs when the direction and magnitude of velocity remain constant.

    If a body has uniform velocity, the rate of change of velocity is constant (DV/dt=0), and the rate of change of velocity is acceleration (DV/dt=a), so (a=0) when these two statements are compared. As a result, acceleration is zero.

    When a particle moves with a uniform velocity, the slope of a displacement-time graph (Fig) is constant at all points.

    Uniform Velocity Example

    It is a stable velocity, i.e., the velocity that does not change with time in scale or direction in space. This means that a body has this type of velocity if it travels at a constant speed along an instant line (i.e., in an exacting direction). There has been no change in either speed or direction.

    It occurs when the time rate of disarticulation alteration does not change with time intervals. When a truck travels equivalent distances in equivalent time intervals, we say the body has this type of velocity.

    This is the velocity with which a body moves once it is started on a frictionless surface. All circular motion is an example: the movement of a fan and our clock hand. Let us learn about more examples of uniform velocity below.

    Examples of uniform velocity

    The following are some examples:

    • The Moon’s orbit around the Earth
    • The movement of a watch’s hands
    • Earth’s Rotation Earth’s Revolution
    • Raindrops fall on the Earth’s surface. This is the velocity with which a body moves once it is started on a frictionless surface.
    • All circular motion is an example: the movement of a fan and our clock hand.

    Non-uniform velocity

    Non-uniform velocity occurs when unequal displacement occurs within the same time interval. It is also referred to as variable velocity. An object travels unequal distances in equal time intervals in a specific direction. It is said to move with a non-uniform or variable velocity if the direction of motion changes.

    A constant-speed revolving fan, for example, has variable velocity. The velocity is variable (non-uniform) if it covers unequal displacements in equal time intervals, if the direction of motion changes, or if the rate and direction change.

    A body is moving at a constant speed in a circular path: In this scenario, the body is moving at a constant speed but changing direction at every instant because a circle is considered a polygon with infinite edges, so the body is moving with non-uniform velocity.

    A body moves in a straight line at a variable speed: In this case, the direction of motion is constant, but the speed of the body changes, so it is said to be traveling at a non-uniform velocity.

    A body is moving at a variable speed in a rectangular path: In this case, the body is traveling at a non-uniform velocity because both the speed and direction of the body are changing.

    FAQs

    What are some non-uniform velocity examples?

    For example, if a vehicle moves in a circular path at a uniform speed, its velocity is said to be non-uniform because the direction of the moving body changes along with the direction of the curve on a circular path.

    What is the difference between uniform speed and uniform velocity?

    When an object's speed does not change, it is said to be traveling at a uniform speed. When an object travels at a constant speed without changing direction, it is said to have uniform velocity.
