Is momentum conserved in all of the experiments? Please give a complete description with examples as needed supporting your response.

2.Is kinetic energy conserved in all of the experiments? Please give a complete description with examples as needed supporting your response.

Does friction affect this experiment? If so, how? If not, why not?
If the track were not perfectly level, how would your results change if at all?
How might this experiment be improved to illustrate better the concepts of conservation of momentum and kinetic energy?

Expert Solution

1) Yes, Momentum is conserved in almost all the experiments. In elastic collision as well as In inelastic collision. The total momentum of the system is always conserved.

Example - Two objects moving at some velocity collide and bounce back in respective direction.

Two objects move towards each other and stick together and move as a one single object.

2) Kinetic energy is conserved in the case of elastic collision but it is not conserved in inelastic collision as some of the energy might get lost. To find if kinetic energy is conserved or not, just find the difference between final and initial kinetic energy of the system , if the difference is zero or nearly zero then energy is conserved.

3) No, for this experiment, friction does not have ample effect as air track minimizes the friction by creating an air cushion between track and glider.

4) This can be answered by you only as you performed the experiment.

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...

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...
