What devices will you use to measure the mass and the volume of water in Part A of this lab?
In this lab, a beaker, two graduated cylinders and a burette will be used to measure liquid volumes, and their precision will be compared. Note that when measuring liquid volumes, it is important to read the graduated scale from the lowest point of the curved surface of the liquid, known as the liquid meniscus.
How did Galileo measure acceleration?
One of Galileo’s contributions to the founding of modern science was his study of falling objects. He turned, then, to measuring the acceleration of objects rolling down smooth ramps. The ramp “diluted” the acceleration to a value small enough to allow accurate measurements of the longer time intervals.
How does mass affect speed of a rolling object?
Mass doesn’t affect speed directly. It determines how quickly an object can change speed (accelerate) under the action of a given force. Lighter objects need less time to change speed by a given amount under a given force.
What is the most accurate tool to measure volume?
Volumetric flasks, burettes, and pipettes made for measuring small amounts of liquid are the most accurate, with tolerances of less than ±0.02. Research and testing require precise measurements, and many lab vessels are even designed to account for the liquid residue that clings inside a flask.
Does speed increase with mass?
The mass of an object does not change with speed; it changes only if we cut off or add a piece to the object. Since mass doesn’t change, when the kinetic energy of an object changes, its speed must be changing. Special Relativity (one of Einstein’s 1905 theories) deals with faster-moving objects.
How to make a size and Distance box?
Position the two posterboard flaps inside the box about 1 inch (2.5 cm) from the end with the two holes (see diagram below). Tape or glue the flaps to the inside sides of the box. Insert the straws into both sets of holes.
How to calculate the mass of an object?
While mass is defined by F = ma, in situations where density and volume of the object are known, mass is also commonly calculated using the following equation, as in the calculator provided: m = ρ × V In the above equation, m is mass, ρ is density, and V is volume.
Is the mass calculator based on density or volume?
This is a basic mass calculator based on density and volume. This calculator takes and generates results of many common units. What is mass? Mass is typically defined as the amount of matter within an object.
How is mass measured in the metric system?
In the metric system, weight is measured in Newtons following the equation W = mg, where W is weight, m is mass, and g is the acceleration due to gravitational field.
