A physical balance (or beam balance) works on the principle of moments. According to the principle of moments, in equilibrium, sum of anticlockwise moments = sum of clockwise moments.

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.

Balance is the distribution of the visual weight of objects, colors, texture, and space. If the design was a scale, these elements should be balanced to make a design feel stable. Emphasis is the part of the design that catches the viewer’s attention.

In simple terms a physical balance is a weighing instrument which helps in measuring the mass of a substance or more specifically the gravitational mass of the substance.

Common balance is the balance which has each arm suspended. The unknown mass is placed in one arm and the known mass in another until they both become equal. Therefore this balance works on the principle of moment of weights. When the weights become balanced, equilibrium is attained.

A physical balance can be used to measure both mass and weight of an object. Basically, a physical balance is simply a weight measuring instrument. It is used to measure the weight of any unknown object with the help of the other object with known weight.

Common balance is used to find unknown mass by using known standard masses. By adjusting levelling screw the plumb line is brought just above the pointed projection on the balance. The beam is raised using the lever and checked that the pointer swings equally on either side of the zero mark.

The mass of a body is the amount of matter present in it. The mass of a body is always constant, and its SI unit is the kilogram. The mass of a body is measured with a physical balance up to 1 milligram accurately.

• Least count of a measuring instrument is the least value of physical quantity that can be measured accurately using the instrument.
• For example,
• Take a spring balance whose range is 0-25kg.
• Measurement=1kg.
• Number of divisions=10.
• Least count=1/10 =0.1kg or 100g.

The formula of Vernier calliper least counts is determined by dividing the smallest reading of the main scale with the total number of vernier scale divisions. The LC of vernier calliper is the difference between one smallest main scale reading and one smallest vernier scale reading of 0.1 mm 0r 0.01 cm.

Majority of times you will find an electronic analytical balance suitable for weighing your samples and reference standards. The readability or least count of such balance is 0.1mg or 0.0001gm.

Balance is not directly related to muscle health, but it is important to your overall physical well-being. One element in a well-rounded fitness program, balance helps you to avoid injury and improve coordination. As balance decreases as we age, it is important to practice simple balancing exercises regularly.

Age, gender, and height have all been shown to impact an individual’s ability to balance and the assessment of that balance. Typically, older adults have more body sway with all testing conditions.

It’s a good idea to include balance training along with physical activity and strength training in your regular activity. Nearly any activity that keeps you on your feet and moving, such as walking, can help you maintain good balance.

Some strength is also important for balance. Strong hip, knee, and ankle muscles will give you a solid foundation and help you stay upright (for more on strength and other types of exercise, see “Selected resources”).

How to Maintain and Improve Your Balance as You Age

1. One-foot balance. When was the last time you stood on one foot for more than two seconds?
2. Sit and stand. Besides helping with balance, this acts as a leg strengthener as well.
3. Walk the balance beam. Walk heel to toe across the floor like you are walking along a balance beam.
4. Lunges.
5. Learn Tai Chi.
6. Yoga.
7. Mini trampoline.

Your abdominal, back, and hip muscles can help you avoid falls.

4 Training Tips to Improve Balance and Coordination

1. Close your eyes while you perform exercises. When you close your eyes, you should still have a general sense of where your body is.
2. Perform balance exercises to improve your coordination.
3. Incorporate strength training into your workout.
4. Use plyometric exercises to improve your sense of self.
