Upthrust Force: Definition and 2 easy Examples
Upthrust force, also known as buoyant force, is the upward force exerted by a fluid (liquid or gas) on an object that is submerged or floating within it. This force acts in the opposite direction to the force of gravity and is what makes objects float or appear lighter when submerged in a fluid. Therefore,…

5 Electric field patterns: Easy
Electric field patterns represent the direction and strength of the electric field created from charged objects. The electric field is a vector field. It shows the force exerted on a positive test charge at any point in space. Electric field patterns show how charged objects interact.

Bar Graphs: concise Introduction1
Bar graphs consist of vertical or horizontal rectangles. These rectangles are drawn on a Cartesian plane. They represent a particular data item with its frequency. Bar charts are especially effective with numerical data. This is when the data splits nicely into different categories. You can quickly see trends within your data. They are best used to:…

Measuring mass: 7 Instruments to use
Measuring Mass is equivalent to determining the quantity of matter in a substance. Matter is anything that occupies space. The mass of an object depends on it’s size and the number of particles it holds. The SI unit of mass is the Kilogram (Kg). A kilogram is the mass of a piece of platinum-iridium metal.…

Measuring Volume
In physics, Measuring volume is a measuring of the three-dimensional space occupied by a substance or enclosed within a container. It is typically measured in cubic units such as cubic meters (m³) or cubic centimeters (cm³). Volume as a three dimensional quantity, is obtained when three lengths are multiplied together. Another popular definition is that volume…

1:Measuring Area: Precise discussion
Measuring Area is finding the quantity that expresses the extent of a given surface on a plane. It is a derived quantity of length. Area is obtained from product of two lengths. The SI Unit of area is square meter (m2). square meter can be expressed into other units like square-centimeter (cm2), square-millimeter(mm2) or square-kilometer…
