Impulse-Momentum Theorem00:49

Impulse-Momentum Theorem

18.8K
The total change in the motion of an object is proportional to the total force vector acting on it and the time over which it acts. This product is called impulse, a vector quantity with the same direction as the total force acting on the object.
By writing Newton's second law of motion in terms of the momentum of an object and the external force acting on it, and simultaneously using the definition of the impulse vector, it can be shown that the total impulse on an object is equal to its...

Impulse

21.2K
According to Newton’s second law of motion, the rate of change of the momentum of an object is the net external force acting on it. The total change in momentum between two timepoints thus depends on both the external force acting on it and the time over which it acts. Describing this mathematically, the total change of an object’s motion is proportional to the force vector and the time over which it is applied. This product is called impulse.
Additionally, it can be shown that the...

Principle of Impulse and Moment01:15

Principle of Impulse and Moment

457
When one considers a rigid body undergoing a plane motion, which is essentially a blend of translational and rotational movement, the application of Newton's second law gives the formula for the translational movement of such a body. If this equation is multiplied by a time interval, dt, and then integrated over the limits of integration, it results in an equation that embodies the principle of linear impulse.

Summary

Slower walking speeds increase frontal plane hip moment impulse, a risk factor for hip osteoarthritis progression. This finding in healthy adults suggests reduced walking speed may worsen hip joint loading in osteoarthritis patients.

Area of Science:

  • Biomechanics
  • Orthopedics
  • Gerontology

Background:

  • Increased frontal plane hip moment is a risk factor for hip osteoarthritis progression.
  • The impact of decreased walking speed on hip moment impulse in osteoarthritis is not well understood.

Purpose of the Study:

  • To investigate the relationship between reduced walking speed and frontal plane hip moment impulse.

Main Methods:

  • Treadmill walking trials were conducted at various speeds (40% to 100% of comfortable non-dimensional speed) in 17 older adults.
  • Frontal plane hip moment impulse (non-normalized and normalized to step length) was calculated for each speed condition.
  • Regression analysis examined the association between walking speed and hip moment impulse.

Main Results:

  • A significant increase in frontal plane hip moment impulse was observed with decreased walking speed.
  • The relationship between walking speed and hip moment impulse followed a second-order polynomial.

Conclusions:

  • Reduced walking speed elevates frontal plane hip moment impulse in healthy older adults.
  • This suggests that slower walking may exacerbate hip joint loading in individuals with hip osteoarthritis.
