Key Takeaways: Measure Mass Using a Balance
- A balance or scale is an instrument used to measure mass in the science laboratory.
- One common method of measuring mass is to tare the scale and measure the mass directly. For example, this is how people weigh themselves.
- The other common method is to place a sample into a container and measure the mass of the container plus sample. ...

- Foreground and background can balance each other.
- Items can also balance each other along a diagonal axis, not just vertical or horizontal.
What does balance mean in science terms?
balance ( ˈbæləns) n 1. (General Physics) a weighing device, generally consisting of a horizontal beam pivoted at its centre, from the ends of which two pans are suspended. The substance to be weighed is placed in one pan and known weights are placed in the other until the beam returns to the horizontal. See also microbalance
What is a balance used in science?
Balance, instrument for comparing the weights of two bodies, usually for scientific purposes, to determine the difference in mass (or weight). The invention of the equal-arm balance dates back at least to the time of the ancient Egyptians, possibly as early as 5000 bc.

bal·ance. (băl′əns) To adjust a chemical equation so that the number of each type of atom, and the total charge, on the reactant (left-hand) side of the equation matches the number and charge on the product (right-hand) side of the equation.

What is a balance in chemistry?
Chemical balance is a beam balance instrument that is used in a quantitative measure of the chemical with great precision. It measures the mass of the chemical up to four decimal places. It is used in the quantitative analysis of the chemical. It has the ability to recognise any minimal deviation.
What does balance mean in physics?
Translation: When two forces act upon each other in opposite directions, and they are both the same size, we say they are balanced.
What is balance and example?
The definition of balance is the amount of something left over after additions and subtractions have been made. An example of balance is the money owed on taxes after all income has been calculated and deductions have been figured. noun.
What is a balance used for in biology?
Balance: A biological system that enables us to know where our bodies are in the environment and to maintain a desired position. Normal balance depends on information from the inner ear, other senses (such as sight and touch) and muscle movement.
What is balance and unbalance?
When the forces acting on an object have equal strength and act in opposite directions, they are balanced. These forces cancel out one another, and the motion of the object they are acting on remains unchanged. When the forces acting on an object are unbalanced, they do not cancel out one another.
Does balance mean equal?
a state of equilibrium or equipoise; equal distribution of weight, amount, etc. something used to produce equilibrium; counterpoise. mental steadiness or emotional stability; habit of calm behavior, judgment, etc. a state of bodily equilibrium: He lost his balance and fell down the stairs.
What is the best example for balance?
Examples of balance exercises include:Standing with your weight on one leg and raising the other leg to the side or behind you.Putting your heel right in front of your toe, like walking a tightrope.Standing up and sitting down from a chair without using your hands.Walking while alternating knee lifts with each step.More items...•
What is a balance force?
Balanced forces are those that are opposite in direction and equal in size. Balanced forces are considered to be in a state of equilibrium. When forces are balanced there is no change in direction. Combined forces that are balanced are always equal to zero. (
What are the types of balance?
There are three different types of balance: symmetrical, asymmetrical and radial. The human figure in this diagram is symmetrically balanced; the same on the left and right sides of a central axis.
What is the balance of the body?
What is balance? Balance is the ability to maintain the body's center of mass over its base of support.
What is a state of balance in the body?
1. Homeostasis refers to an organism's ability to regulate various physiological processes to keep internal states steady and balanced.
What called the balance of the body?
The vestibular system is one of the sensory systems that provides your brain with information about balance, motion, and the location of your head and body in relation to your surroundings. There are three loops in your inner ear, called semicircular canals.
How do you balance an object in physics?
The line of gravity helps you determine balance; if it passes through the base of support then the object is in balance. If the line of gravity touches the ground at a point outside the base of support then the object will tip over.

Background
We sometimes use “centre of mass” and “centre of gravity” to mean the same thing. Technically, however, they are different. Centre of mass means “the average location of all the matter in an object”. The centre of gravity is the average location of the force of gravity on an object.
Vocabulary
balance (d) – A state in which opposing forces on an object reach equilibrium, so that the object is stable and not about to fall over.
What is the principle of balance?
…to prove the principle of balance: that two weights are in equilibrium when they are inversely proportional to their distances from the fulcrum. From this principle he developed a theory of the centres of gravity of plane and solid figures. He was also the first to state and prove the…
What is hysteresis in physics?
Hysteresis, lagging of the magnetization of a ferromagnetic material, such as iron, behind variations of the magnetizing field. When ferromagnetic materials are placed within a coil of wire carrying an electric current, the magnetizing field, or magnetic field strength H, caused by the current forces some or all of the….
What does the difference between zero reading and reading with the pans loaded mean?
The difference between the zero reading and the reading with the pans loaded indicates the difference between loads in scale divisions.
