Nov 19, 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.
Mar 26, 2020 · Define velocity ( class 9) 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 ...
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.
Jun 10, 2021 · 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. Answer: It is represented by the equation: vrms=√3RTM v r m s ...
Jan 20, 2021 · Velocity is equivalent to a specification of an object's speed and direction of motion (e.g. 60 km/h to the north). Velocity is a fundamental concept in kinematics, the branch of classical mechanics that describes the motion of bodies. i tnk this is the answer. if correct plz make me Brainlist...
Jun 21, 2024 · The velocity of an object is the rate of change of its position with respect to a frames of reference and is a function of time. Velocity is equivalent to a specification of its speed and direction of motion (e.g. 60 km/hr to the north). Explanation: please mark brainlyist Mark please
Jan 10, 2024 · Define velocity. State the S I unit of velocity. 2. Dis nguish between uniform circular mo on and linear mo on. 3. Draw a velocity- me graph to show the following mo on. A car accelerates uniformly from rest for 5 seconds and then it travels at a steady velocity for 5 seconsds.Calculate the total distance travelled from the graph. 4.
Jan 16, 2021 · the escape velocity of a body is the velocity requered for a body to overcome the gravitational force of earth and escape from it's feild of attraction. expression :-V= root 2GM/R. escape velocity depends on the mass of earth (M) and radius of earth(R) these are the two factors which escape velocity depends. Explanation:
Nov 15, 2017 · Define angular displacement, angular velocity and angular acceleration. Angular displacement is defined as the angle through which an object moves on a circular path. It is theangle, in radians, between the initial and final positions. (θf - θi) = angular displacement. θ = s/r. Angular acceleration is the rate of change of angular velocity.
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.
