Relationships between position, velocity, acceleration, and time are studied. This lab focuses on the one dimensional case where each quantity can be considered as a scalar. Acceleration is taken to be constant while the mass varies.
Students will investigate the principle of momentum conservation by studying collisions in one dimension using two bodies/ gliders. Energy conservation will also be explored by analyzing elastic and inelastic collisions.
In this experiment students measure the speed of a projectile by a kinematic method and also by the use of a ballistic pendulum. The latter method illustrates the use of conservation of energy and momentum.
To investigate the relationship between torque, moment of inertia, and angular acceleration for a human arm. Bicep force vs mass, triceps extension, and rotational inertia of the forearm will be observed.
