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 also taken to be constant.
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 how the pressure between a given quantity of gas in a fixed volume varies with temperature. This linear relationship between pressure and temperature is extrapolated to zero pressure. The temperature at which this occurs is absolute zero.
