Momentum Flashcards
In Perfectly elastic collision:
- momentum is conserved
- kinetic energy is conserved
Linear momentum is the product…
of the mass of the object and its velocity.
Linear momentum is…
vector quantity.
Conservation of momentum:
Within a closed system, the total momentum in any direction is constant.
The total momentum of objects before collision=
the total momentum of objects after the collision
In a perfectly elastic collision, the relative speed of approch=
the relative speed of separation.
In an inelastic collision:
- momentum is conserved
- kinetic energy not conserved(deformation)
When deforming objects, work…
is done.
Momentum is always…
conserved in all collisions.
Newton’s second law of motion(momentum)
The resultant force acting on an object is equal to the rate of change of change of its momentum. The resultant force and the change in momentum are in the same direction.
