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.
Newton's 1st Law is investigated. The apparatus consists of a force table, and a set of movable pulleys with weights. A string is attached to a small ring at the top of the table which is centered with a pin.
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.
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.
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.
