In which of these collisions would angular momentum NOT be
conserved?
A) A collision in which linear momentum is also conserved
B) A collision which is perfectly inelastic
C) A collision which is perfectly elastic
D) A collision with a net external torque
Is the angular momentum of a planet conserved as it orbits a
star? Explain your answer using torque. Conservation of angular
momentum:
The angular momentum of an object or system is conserved
whenever the total external torque on the object or system is zero.
τ ⃗_ext=0 → ∆L ⃗=0
How does a newton cradle visually demonstrate how NRG and
momentum are conserved. I konw it works mathematically but how does
releasing balls and having the other two balls on the other side
swing up demonstrate momentum and conservation of NRG.
the
total momentum (linear momentum) is conserved in any collision, not
its _________ energy, but its total energy is conserved.
In the ballistic pendulum shown in the conservation of linear
momentum lesson, if the mass of a bullet is m1 = 10 g and the mass
of the block is 8.0 kg and the height that both reach is 5.0 cm,
the initial speed of the bullet is _______ m / s.
In the Newton pendulum or Newton's cradle the...
Kinetic energy is conserved in an elastic collision by
definition. Show, using the Galilean transformation equations, that
if a collision is elastic in one inertial frame it should be
elastic in all inertial frames
1. Show that the Kinetic Energy and the Momentum are conserved
in this system. (Remember that momentum is a vector, so you need to
show the conservation of the momentum in x and y directions
separately.)
Data:
Before the collision: m1= 1kg v1x
=1 m/s v1y=0 m/s m2=1kg v2x=-1m/s
v2y=0 m/s
After the collision: m1= 1kg v1x
=-0.778 m/s v1y=-0.629 m/s m2=1kg
v2x= 0.778 m/s v2y=0.629 m/s
2. From the data, calculate the direction(angles) of the final
velocities of the...
1)What is energy? Is it conserved, and how is this conservation
different than momentum?
2) What is the difference between a closed system and an
isolated system?
3) What is the difference between elastic, inelastic,
totally inelastic, and super-elastic collision?
4) What is Mazur's notation for relative
velocity and what is relative velocity anyway?
A. Starting from the assumption that angular momentum is
conserved, prove Kepler's second law, the constancy of areal
velocity.
B. Starting from Kepler's first and second laws and Newton's
Universal Law of Gravity, prove Kepler's third law (The Harmonic
Law).
