Motion and Measurement of Distances Test - 1

Explanation:

Motion in which direction keeps on changing is called random motion. So, When the motion of the object is not along a fixed path with changing direction is a random motion.

Explanation:

Vibratory motion can be described as any object moving/swinging back and forth, moving up and down, pulsating, spinning, or vibrating. When a body moves to and fro about its mean position is called vibratory motion.

Explanation:

Linear motion, also called uniform motion or rectilinear motion, motionin one spatial dimension. A bullet fired from a gun shows in straight line. So motion a bullet shows when fired from a gun is linear motion.

Explanation:

If an object repeats its motion along a certain path, about a certain point, in a fixed interval of time, the motion of such an object is known as periodic motion. A moving swing has periodic motion as it repeat the same at certain interval of time.

Explanation:

Millimeter is a metric length unit and equal to one thousandth of a meter. There are 10 millimeters in a centimeter.

Explanation:

The process by which something moves from one position to another is referred to as motion; that is, a changing position involving time, velocity and acceleration.So,  motion is a change in position of an object over time.

Explanation:

In the metric system of measurement, the most common units of distance are millimeters, centimeters, meters, and kilometers. Feet, Cubit and Angul all are ancient unit of measurement and meter is  not a/ an ancient unit of measurement.

Explanation:

A hectare is a unit of area equal to 10,000 square meters. Usually used to measure land.

A square 100 meters on each side has an area of 1 hectare.

Symbol: ha

1 ha = 2.47 Acres approximately.

Explanation:

Kilometer is a metric length unit and equals to 1000 meters. It is spelled as kilometre in europe. It is a commonly used unit of length in most of the countries to measure the distance between two geographical locations.

Explanation:

1 day = 24 hours, 1minute = 60 second and 1 second represent time interval. But Time of sunrise is not constant its vary day by day so time of sunrisere not presents a period of time or time interval.
