QUESTIONS:
- Is the mechanical energy remaining the same (conserved) with time?
- Is the decrease in the potential energy get completely converted into the kinetic energy?
- What is the cause of any mechanical energy loss in this experiment?
- Since energy is never really lost, what types of energy was this “loss” transferred into?

Remarks Because the impact is inelastic, it would be incorrect to equate the initial kinetic energy of the incoming bullet to the final gravitational potential energy associated with the bullet-block combination. The energy isn't conserved! Question---- The ways that mechanical energy is lost from the system in this experiment include: (Select all that apply.) 1) energy loss from the change in height of the block. 2) energy loss because the kinetic energy of the bullet becomes the kinetic energy of...

A 0.45 kg object rests on a frictionless horizontal surface, where it is attached to a massless spring whose k-value equals 24.0 N/m. Let x be the displacement, where x = o is the equilibrium position and x > 0 when the spring is stretched. The object is pushed, and the spring compressed, until хі =-4.00 cm. It then is released from rest and undergoes simple harmonic motion. (a) What is the object's maximum speed (in m/s) after it is...

Elastic collisions: one at rest one moving, two colliding, both initially moving the same direction. Inelastic collisions: one at rest one moving, two colliding, both initially moving the same direction. Perfectly elastic collisions: one at rest one moving, two colliding, both initially moving the same direction. Questions1. Was momentum conserved for all types of collisions you examined in this experiment? If not, explain the cause of losing orgaining momentum.2. Was total velocity conserved for all types of collisions you examined...

Conservation of energy In the examples you have examined in this lab, as the coaster travels down the track its gravitational potential energy decreases, and its kinetic energy increases. At any point along the path of the coaster, the potential energy plus the kinetic energy add up to the same value. In the absence of friction and air resistance, we find that the total energy (kinetic plus potential) stays the same. For this reason, physicists call the total energy a...
