When an object's velocity is changing, the forces must be...When an object's velocity is changing, the forces must be...

Respuesta :

We need the relationship between force and velocity

There are two ways

  • Go through acceleration process (Apply Newton's law)
  • Go through the momentum process(Quite difficult)

Let me use the second way

[tex]\\ \sf\longmapsto p=mv[/tex]

[tex]\\ \sf\longmapsto p\propto v[/tex]

According to Newton's second law

[tex]\\ \sf\longmapsto F=\dfrac{dp}{dt}[/tex]

[tex]\\ \sf\longmapsto F\propto p[/tex]

Now

[tex]\\ \sf\longmapsto F\propto v[/tex]

  • When velocity is more force must be more and vice-versa.

Key words:-

  • Momentum=p
  • Mass=m
  • Velocity=v
  • Force=F
