Assignment 15 

Impulse, momentum and the impulse-momentum theorem are introduced.  We continue working with force, work and energy, with an emphasis on elastic potential energy and its conversion to other forms of energy.  You will consider the design of a simple balance.  In the text we begin the chapter on work and energy, for which previous assignments will have substantially prepared you.

In the Introductory Problem Set assignment the concepts of impulse and momentum are introduced, along with the impulse-momentum theorem.

The qa independently introduces impulse and momentum and the impulse-momentum theorem.

The 'seed' problem addresses the potential energy of an 'ideal' rubber band and the transfer of that energy to kinetic and potential energies of domino.

In the lab exercise you will view a video describing a simple balance which relies on buoyant forces for stability and changes in force.

In the text you will begin reading and doing problems related to work, kinetic energy, potential energy and conservation of energy.
