Note that speed has no direction (it is a scalar) and the velocity at any instant is simply the speed value with a direction. Calculating Average Speed and Average Velocity As an object moves, it often undergoes changes in speed. For example, during an average trip to school, there are ...
If we say at every instant of time—and assume that time is composed of instants—then we invite the arrow paradox of Zeno. At any one instant, he argued, there is no interval of time, hence there is no change of position; which means: no motion....
Instantaneous speedis the speed at any instant Measured by a speedometer A speedometer measures the instantaneous speed Uniform Speed When there is a constant rate of change in the object’s distance covered per unit of time, we say that the object is experiencing constant or uniform speed. ...
The position of the particle at any instant is defined by the distance, s, along the curve from a fixed reference point. The velocity vector is always tangent to the path of motion (t-direction). The magnitude is determined by taking the time derivative of the path function, s(t). ...
Be able to obtain the instantaneous speed at any particular instant from a curving distance-time graph. 6. Acceleration is defined to be a = Δv/Δt. Another useful formula is v = vo + at. Remember that an object starting from rest (vo = 0) and moving with constant acceleration, trav...

1)Why does acceleration at any instant does not depend upon velocity at any instant? What is the velocity when a particle travels 0.23 m in 29 ns? Is the instantaneous speed always equal to the magnitude of the instantaneous velocity? Is the average speed always equal to the magnitude of ...
