#1 Work lab
concept | The mathematical product of a force and the parallel distance through which it operates is known as work. A system can do work only if it has energy. | Equipments | inclined plane Hall’s carriage 500, 750, and 1000 gram masses newton scale masking tape meter stick |
purpose | Students collect data for towing objects of varying mass up an inclined plane at various angles to develop the concept of work. |

#2 Simple Harmonic Motion Lab
concept | SHM is a type of periodic, oscillatory motion in which the cause of motion is a restoring force of the form F= -kx. This relation, known as Hooke's law, shows that the force responsible for the periodic motion must be oppositely directed to the oscillating object's displacement(toward the equilibrium position) and proportional in magnitude to the displacement | Equipments | steel measuring tape string or spring stopwatch masses with various weight |
purpose | Students find out the period of motion while doing simple harmonic motion. |

#3 Energy lab
concept | The Work-Energy Theorem states that the work done on a body by an external force is related to the resulting change in kinetic (K) and/or potential (U) energy. |
Equipments | track and object meter stick balance stopwatch |
purpose | students prove that the energy is conserved, by observing the energy state in motion. |
