Respuesta :
The particle moves at a speed of 20 m/s at time t = 0 or t = 5 seconds, respectively. The t-value calculates the magnitude of the difference in relation to the variance in your sample data.
What does velocity vs. speed mean?
Velocity, as opposed to speed, refers to the pace of direction of the an object's movement as it moves down a path. In other words, whereas velocity is a vector, speed is a scalar quantity. a=dvdt=d2xdt2
How do velocity and acceleration differ?
Velocity refers to the speed at which displacement changes. The pace at which speed changes is known as acceleration. Because it consists both of magnitude and direction, the velocity is a vector quantity. Since acceleration is merely the rate at which velocity changes, it too is a vector quantity.
