Mar 25, 2020 · Velocity is defined as the rate of change of motion or object's position with respect to a frame of reference and time. Velocity is a vector quantity which means we need both magnitude and direction. It is also called the rate of change of displacement. When there is a change in magnitude or direction of the velocity of a body then the body is ...
May 8, 2024 · Velocity is a fundamental concept in kinematics, the branch of classical mechanics that describes the motion of bodies. It is defined as the speed in combination with the direction of motion of an object. Velocity is a physical vector quantity, which means that both magnitude and direction are needed to define it.
Jun 10, 2021 · Brainly User. report flag outlined. Answer: The root-mean square (RMS) velocity is the value of the square root of the sum of the squares of the stacking velocity values divided by the number of values. The RMS velocity is that of a wave through sub-surface layers of different interval velocities along a specific ray path.
Aug 25, 2024 · Answer: Velocity is defined as the rate of change of distance of a body with respect to time. Its unit in SI is m/s.
Jun 19, 2018 · Uniform velocity of an object moving along straight line is defined as the ratio of dislacement to time of covered distance atconstant or uniform speed. it is also calleduniform linear velocity. v=s÷t. 3.0.
Jul 22, 2023 · Velocity is a measure of the rate of change of an object's position over time, in a specific direction. It is a vector quantity, which means it has both magnitude (speed) and direction. For example, if a car travels 60 miles in one hour to the east, its velocity is 60 miles per hour to the east.
Nov 18, 2020 · Define speed and velocity. Write their S.I units. Ans : Speed and velocity are both measured using the same units. The SI unit of distance and displacement is the meter. The SI unit of time is the second. The SI unit of speed and velocity is the ratio of two — the meter per second. Explanation: A body is moving with a velocity of 15 m s.
Jan 11, 2018 · Define velocity of projection. Answer: VELOCITY: The velocity is defined as the rate of change of displacement of an object in the particular time taken. Velocity (V) The S.I. unit of velocity is m/s. VELOCITY OF PROJECTION: The velocity in which the object is projected or the speed and time difference in which the object is projected it is ...
Jul 13, 2024 · Certainly! Let's define velocity, acceleration, and address whether a body can have zero but constant acceleration: 1. **Velocity:** - Velocity is a vector quantity that describes the rate of change of an object's position with respect to time.
Apr 24, 2024 · ®©Define : INSTANTANEOUS VELOCITY®© Instantaneous velocity is defined as the rate of change of position for a time interval which is very small (almost zero). Measured using SI unit m/s. Instantaneous speed is the magnitude of the instantaneous velocity. It has the same value as that of instantaneous velocity but does not have any direction.
