The motion seen in a merry-go-round is called circular motion. In this type of motion, the objects, like the seats or horses on the merry-go-round, move in a circular path around a central point. As the merry-go-round spins, the objects ...

To measure very small lengths, we use units like millimeters (mm) and micrometers (μm). One millimeter is one-thousandth of a meter, and a micrometer is one-millionth of a meter. These units are useful for measuring small objects, like the thickness ...

Length is expressed in terms of measurement using standard units like meters (m), centimeters (cm), and millimeters (mm). The meter is the basic unit of length in the International System of Units (SI), and smaller lengths are often measured in ...

Linear motion is the movement of an object along a straight path. In this type of motion, the object moves in one direction without changing its path. For example, a car driving down a straight road or a ball rolling ...

Traditional units of length, like a “foot” or a “yard,” can be unreliable because they vary from person to person or place to place. For example, one person’s foot might be longer than another person’s, making measurements inconsistent. Also, these ...

To measure the length of a thread, you can use a ruler or a measuring tape. First, stretch the thread straight along a flat surface. Then, use the ruler or tape to measure from one end of the thread to ...

If the ends of a scale are broken, it becomes difficult to measure accurately. The scale may no longer have clear starting or ending points, which can lead to errors in measurements. For example, if the zero point is missing, ...

The smallest measurement unit on a typical ruler is usually 1 millimeter (mm). A millimeter is one-tenth of a centimeter, and most rulers have small marks between the centimeters to show these millimeters. These tiny divisions help measure objects more ...

To measure the length of a curved line, you can use a thread or a flexible measuring tape. First, place the thread along the curved line and carefully follow the shape of the curve. Once the thread covers the entire ...

Oscillatory motion is the repetitive back-and-forth movement of an object around a central point or position. It occurs in a regular pattern, where the object moves to one side, then returns to the original position, and repeats the motion. A ...
