Velocity and Position by Graphical Method01:34

Velocity and Position by Graphical Method

9.2K
Velocity and position can be calculated from the known function of acceleration as a function of time. The total area under the acceleration-time graph and the velocity-time graph gives the change in velocity and position, respectively. In the case of an airplane, its acceleration is tracked using the inertial navigation system. The pilot provides the input of the airplane's initial position and velocity before takeoff. The inertial navigation system then uses the acceleration data to...

Velocity and Acceleration in Steady and Unsteady Flow

264
In fluid mechanics, velocity and acceleration are key concepts for analyzing particle motion in both steady and unsteady flow. Consider a fluid particle moving along a pathline, where its velocity depends on its position and time. The particle's acceleration is obtained by differentiating the velocity with respect to time.
The acceleration can be generalized to any point in the flow, and expressed as components along three perpendicular directions, representing changes in velocity over...

To calculate the other physical quantities in kinematics, we must introduce the time variable. The time variable allows us not only to state the position of the object during its motion, but also how fast it is moving. The speed at which an object is moving is given by the rate at which the position changes with time. For each position xi, we assign a particular time ti. If the details of the motion at each instant are not important, the rate is usually expressed as the average velocity. This...

Relative Motion Analysis - Velocity01:24

Relative Motion Analysis - Velocity

A stroke engine has a slider-crank mechanism that converts rotational motion from the crank into linear motion of the slider or vice versa. This mechanism consists of three main parts: the crank, the connecting rod, and the slider.
When an external force is exerted, it sets the crank into a rotational movement. This, in turn, instigates the motion of the connecting rod, leading to what is referred to as a general plane motion. This process involves two key points - point A on the connecting rod...

To calculate other physical quantities in kinematics, the time variable must be introduced. The time variable not only allows us to state where an object is (its position) during its motion, but also how fast it’s moving. The speed at which an object is moving is given by the rate at which the position changes with time. For each position, a particular time is assigned. If the details of the motion at each instant are not important, the rate is usually expressed as the average velocity v.

Velocity and Acceleration of a Wave00:51

Velocity and Acceleration of a Wave

4.5K
A wave propagates through a medium with a constant speed, known as a wave velocity. It is different from the speed of the particles of the medium, which is not constant. In addition, the velocity of the medium is perpendicular to the velocity of the wave. The variable speed of the particles of the medium implies that there must be acceleration associated with it. 
The velocity of the particles can be obtained by taking the partial derivative of the position equation with respect to time....

Area of Science:

  • Sports Science
  • Exercise Physiology
  • Biomechanics

Background:

  • The load-velocity relationship (LVR) is a key indicator of neuromuscular function.
  • Optimizing training programs to enhance LVR adaptations is crucial for performance.
  • Different set configurations may differentially impact LVR.

Purpose of the Study:

  • To investigate the effects of two distinct set configurations on the LVR in bench press and parallel squat.
  • To compare the efficacy of rest redistribution sets versus traditional sets in altering LVR.

Main Methods:

  • A randomized controlled trial with 39 physically active individuals.
  • Training interventions included rest redistribution sets (16x2 reps) and traditional sets (4x8 reps) over 5 weeks.
  • Load-velocity relationships were assessed before and after the training period for both exercises.

Main Results:

  • Both training groups showed changes in bench press LVR (increased intercept, decreased slope).
  • The rest redistribution group demonstrated significant changes in squat LVR (decreased slope, increased intercept).
  • Rest redistribution sets were more efficient in inducing LVR changes, particularly for the squat exercise.

Conclusions:

  • Rest redistribution set configuration is particularly effective for modifying the load-velocity relationship.
  • This training strategy may offer unique benefits for strength and power development.
  • Further research should explore the long-term effects and broader applicability of rest redistribution sets.
