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.What is the unit for kinetic energy?
2.A collision in which kinetic energy is conserved is called
what?
3. It takes no work to hold a cheerleader in the air, as shown
here. If no work is done by the cheerleaders, why do they
eventually tire?
A.The concept of work, as it apples in physics, does not apply
to any process that involves people.
B.Their bodies expend chemical energy as their muscles
function; this is "hard work," but not the...
Elastic Collision lab. I'm trying to calculate velocity,
momentum, and kinetic energy in an elastic collision. The data I
have is this. I tried using these numbers to calculate velocity and
momentum but the results show momentum is not conserved as it
should be. Is that just error from measurements or am I missing
something?
Car A
Car B
length=10cm
length=10cm
weight=189.6g
weight=299.7g
initial=0.153s
initial=0s
final=-0.705s
final=47.2s
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...

How does the total Kinetic Energy before the collision compare
to the total Kinetic Energy after the collision, for the case of
inelastic collisions? How does it compare for elastic
collisions?
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...
Show that energy is conserved in a simple charging RC circuit.
That is show that the total work done by the battery equals the
final energy stored in the capacitor plus the energy dissipated in
the resistor.
