Abstract

In introductory mechanics laboratories there are many simple investigations

that are related to conservation of energy. Often, these investigations

are based upon a simple idea of moving an object up an incline, or rolling

objects down an incline, determining initial and final velocities and change

in gravitational potential energy. However, an electric motor can be used to

make similar measurements at a constant speed by continuously monitoring

the current and voltage as a function of time. This method allows more

complex and interesting investigations.
