Instantaneous Velocity Vector
In everyday use and in kinematics the speed of an object is the magnitude of its velocity the rate of change of its position.
Instantaneous velocity vector. The velocity of an object is the rate of change of its position with respect to a frame of reference and is a function of time. Velocity is equivalent to a. During a typical trip to school your car will undergo a series of changes in its speed. If you were to inspect the speedometer.
Velocity speed and motion. Velocity and speed are very similar ideas but velocity is a vector and speed is not. Suppose we knew that someone was driving. The state of change of velocity of a body with time is known as its acceleration.
If the velocity of a body increases with time then its acceleration. Lesson 1 describing motion with words. Speed is the answer to the question how fast velocity is speed with direction. Speed velocity is the rate of change of distance displacement with time.
