![]() ![]() If you have any question ask using the comment box. Which of the following is mass measuring instruments (a) ruler (b) chemical balance (c) watch (d) clock.The standard unit of mass is -(a) km (b) m (c) g (d) kg.List any four instruments that can be used to measure the mass of objects.It should be noted that the units can be converted from one value to the other, such as: Gram (g) is used to measure wight of light objects while tonne is used to measure very heavy objects. the metric units if mass are kilogram (kg) and tonne (tn). The standard unit of mass in metric system is gram (ng). If the first car weighs 1kg, and the mass of the second car weighs 1kg, then, we say the level balance is equal.īut if the two masses are not equal, the heavier will push the level balance down and the lighter one will go up. Therefore, the mass of the unknown object is equal to the standard masses that counter- balanced it at the other end. The mass of the standard object will be varied until balances the mass of the unknown object. Acceleration is measured in meters per second squared, m/s 2. What is the SI Unit of Moment of Inertia The SI unit of moment of inertia is: kg.m 2. The center of the lever balance is placed on a fulcrum and the object with unknown mass will be placed on end of the lever while the object with a standard mass will be placed on the other side (both at the same distance from the ends). Following are the types of moment of inertia units along with their formula: Area moment of inertia: mm 4 or in 4 Mass moment of inertia: kg.m 2 or ft.lb.s 2 Dimensional Formula: M 1 L 2 T 0. This is achieved by comparing the unknown mass of object with a standard one (known mass). Mass of an object can also be measured using a uniform wooden lever balance. It is defined by taking the fixed numerical value of the Planck constant h to. Bathroom scale Kitchen Scale Hanging Scale Beam balance Chemical balance The kilogram, symbol kg, is the SI unit of mass. The mass of objects can be measured using different measuring instruments such as chemical balance, kitchen scale, bathroom scale, beam balance, unequal arm balance, etc. ![]() defined as 1 (kg m)/s 2, to be used wherever force is designated, in cluding derived units that contain force-e.g., pressure or stress (N/m2 Pa), energy (N'mJ), and power (N·m)/sW. In SI, kilogram is restricted to the unit of mass. When an object has more mass than the other, then it is said to be heavier. is the use of explicitly distinct units for mass and force. For example, a small stone is heavier than a bigger wool. exactly 453.59237 grams (in fact a pound has a metric definition) A short ton is: about the weight of a small car. The mass of the two objects can be compared to judge how heavy or light they are. about the mass of a fluid ounce of water (they are not the same thing though) A pound is: a bit less than half a kilogram. a large object may be lighter than object that is much smaller. the mass on earth is the same as the mass on moon. The mass of an object is the amount of particles in an object. Mass is the measurement of how much matter is contained in an object. Boy measuring his weight using bathroom scale ![]()
