Fabric is suitable for clothing due to its comfort, breathability, and ability to be dyed or patterned. It can be made from natural fibers like cotton or synthetic fibers like polyester, offering various qualities.
Tape and rod measure length like a scale but are more flexible and suited for different contexts. “Char angula” refers to an old measurement unit, meaning “four fingers” or roughly 7-10 cm, used in traditional contexts.
If everyone uses the same meter scale and reads it correctly, the results should be consistent. Differences arise from using various scales or incorrect readings, but a standard meter scale ensures uniform measurements.
When reading a scale, position your eye perpendicular to the scale’s markings to avoid parallax error. This ensures accurate measurement by aligning your line of sight directly with the scale’s markings.
Wrap a flexible measuring tape around the curved base of the tumbler or bottle to measure its circumference. Record the length in centimeters or millimeters, ensuring the tape is snug and level.
Linear motion examples: a car driving on a straight road, a train moving on tracks. Circular motion examples: a fan’s blades spinning, Earth orbiting the Sun. Oscillatory motion examples: a pendulum swinging, a guitar string vibrating.
Accurate time measurement is crucial for coordinating events, scientific experiments, and daily activities.
Motion can be represented on a graph, with time on the x-axis and distance on the y-axis.
Non-uniform motion occurs when an object’s speed or direction changes over time. In this type of motion, the object does not cover equal distances in equal time intervals, resulting in variable velocity.
