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.
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 ...
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 9, 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.
Jan 17, 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:
Feb 25, 2021 · The small drops will have a terminal velocity equal to 10 times the terminal velocity of the big drop. Explanation: please see the enclosed attachment for detailed explanation and step by step working. Terminal velocity= √[ g / k A] g = gravity. k = constant depending on drag , air density etc. A = surface area of the sphere.
Nov 24, 2018 · Answer: The derivation of terminal velocity is . Explanation: As per the data given in the question, we have to derive the expression of terminal velocity. The maximum constant velocity acquired by a body while falling through a viscous medium is called its Terminal Velocity. when force of resistance of a medium is equal and opposite to the ...
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.
May 13, 2024 · Velocity is a measure of the rate of change of an object's position with respect to time. It is a vector quantity, meaning it has both magnitude (speed) and direction. In physics, velocity is commonly expressed in units such as meters per second (m/s) or kilometers per hour (km/h), indicating how fast and in which direction an object is moving.
Sep 18, 2019 · Angular velocity is measured in radian/second or angle/seconds. Similarly the rate of change of angular velocity is angular acceleration. Now we know that if an object is moving in a circular path with constant speed still its velocity will be changing as its direction is changing at every point.
