If we roll a ball down a ramp we can predict the speed of the ball at the bottom of the ramp by using conservation of energy. Why would your prediction always be too high unless you take rotational energy into account?

3. In this question you will do some algebra to determine two relations that you will need for Part 2 of this lab. Write down Eq. 11 twice. In the first statement, set the rotational kinetic energy term equal to zero (i.e. 1/2lo 0) -call this your "No Krot model". Leave the second as it is written in Eq. 11 call this your "Krot model". For both models, solve for v in terms of g, h, and a. In...

Energy of a Tossed Ball In this experiment, we will study energy changes using a Motion Detector. OBJECTIVES: • Measure the change in the kinetic and potential energies as a ball moves in free fall. • See how the total energy of the ball changes during free fall.

Need help With Analysis questions.
Ballistic Pendulum Lab In this lab, you will explore
conservation of Energy and Momentum in an inelastic collision
between a projectile and a cardboard box suspended from a string.
In particular, you will see that the transfer of linear momentum is
easily accounted for in an inelastic collision, but the transfer of
kinetic energy is not easy to measure directly. This is because
Kinetic Energy in collisions transfers to vibrational, acoustic,
and potential energy. Once...
