Experiments and Activities Newtonian Mechanics and Energy

Students have the opportunity to carry out the following experiments:

  • Measurements of length, mass, and time.
  • Experimental verification of vector calculations using the Force Table, representing vectors in magnitude, direction, and sense.
  • Study of parabolic motion, constant and instantaneous velocities, and acceleration in linear motion and free fall.
  • Determination of the relationship between static force on an inclined plane, the angle of inclination, and the coefficient of static friction of various materials.
  • Analysis of linear dynamics and dynamics on an inclined plane to study Newton’s Second Law and verify the equation of motion in uniformly accelerated rotations.

  • Measure pressures, temperatures (of water and refrigerant), power, and energy consumption over time to study the vapor compression refrigeration cycle.
  • Demonstrate the periodicity of stationary oscillators connected by a continuous transverse harmonic wave generated by the wave machine.
  • Analyze the Doppler effect when the sound source or detector moves relative to the propagation medium.
  • Apply steam distillation to separate organic substances that are insoluble in water and slightly volatile from non-volatile substances present in the mixture, such as resins or inorganic salts.
