Average velocity is calculated by the formula V = D/t, where V equals the average velocity, D equals total displacement and t equals total time.
If a force acts in the same direction as the object's motion, then the force speeds the object up. Either way, a force will change the velocity of an object.
For example, someone who takes 40 minutes to drive 20 miles north and then 20 miles south (to end up at the same place), has an average speed of 40 miles divided by 40 minutes, or 1 mile per minute (60 mph). Average velocity, however, involves total displacement, instead of distance.
Velocity Based Training allows coaches and athletes to determine the speed of movement in real time and adjust the weight or exercise accordingly. More and more research is published every day regarding the importance of velocity measures and its correlation with athletes readiness, strength, fatigue and recovery.
Acceleration is the rate of change in the velocity of an object. Velocity can change in three different ways. Speed up, slow down, or changing direction. All three of these changes are technically called acceleration.
These forces may be mechanical, gravitational, electrical or magnetic in nature. To predict the motion of the object, it's often useful to draw a free-body diagram, which is a graphical representation of these forces that depicts the magnitude and direction of each.
Average velocity is defined as the change in position or displacement (∆x) divided by the time intervals (∆t) in which the displacement occurs. The average velocity can be positive or negative depending upon the sign of the displacement. The SI unit of average velocity is meters per second (m/s or ms-1).
as initial and final position are same so its displacement will be 0.
Velocity is equal to rate of change of position vector with respect to time. Average velocity is the ratio of the displacement vector to the corresponding time interval.
Authors concluded that resistance training and velocity monitoring can be effective in enhancing sport specific performance together with endurance and power training in elite athletes.
The easiest way to determine velocity stops for an athlete is to have them perform a reps-to-failure protocol in the specific exercise that you plan to program. Use anything from 60-75% of 1RM and have them perform a set to failure with the given load and monitor velocity for each rep.
Athletes who can move faster than their opponents have an advantage. For example, a faster athlete may be able to get to a ball more quickly than a competitor or may even outrun a pursuer. For this reason, athletes in most sports value speed highly.
