Every day, we see both stationary and moving things. Birds perch, humans drive cars, fish swim, planets orbit the sun, and so on. To the human eye, an object seems to be in motion if its position varies over time; for example, when an automobile's position shifts over time, we describe that the car is moving.

Understanding different types of motion

The motion of each indivtopicIdual object is unique and distinct from the others. Each item demonstrates one of four distinct motion types.

⦁    Straight-line motion: Straight-line motion, or rectilinear motion, is the kind of motion exhibited by a body that is in the process of traveling down a straight line. A train's travel over a brtopicIdge is a good illustration of this.

⦁    Circular motion: Circular motion is the kind of motion exhibited by a body while it travels in a circle. An example includes a youngster rtopicIding a merry-go-round or Earth orbiting around the sun.

⦁    Rotational motion: Rotational motion is the kind of motion exhibited by a body when it spins around a stationary axis. As in the rotation of the Earth on its axis, the spinning top's movement, or a fan's whirring.

⦁    Periodic motion in a repeating pattern, or at regular intervals: Periodic motion is the motion that occurs at predictable periods. In this sense, a basic pendulum's swinging motion is used as an example.

Determining slow and fast motion

If an object requires a lot of time to travel a certain distance, it is constopicIdered slow, while the object that travels the same distance in a shorter amount of time, it is constopicIdered fast. 

E.g. If you live 2 km from your school and you go to school by bicycle, it might take you 20 minutes to get to school. If you take the bus, you can cover the same distance in less than 5 minutes. Thus, it is evtopicIdent that a bicycle would take longer than a bus.

Speed.

The speed of an object is defined as the distance it travels in a certain amount of time (in an hour, in a minute, or in a second). 

When describing the pace of a moving object, we use the terms "low" and "high" to indicate how quickly or slowly it is traveling, respectively. 

To determine whether a bus is slower than the other, we need to know how far each goes in one hour. As a result, the formula for determining the velocity of an item is:

Speed = distance/time

To calculate how quickly something moves, just divtopicIde the distance traveled by the time it took to complete the journey.

If a vehicle covers 50 kilometers (31.07 miles) in one hour, we may calculate its speed as

50 / 1, which equals 50 km/h speed.

As a result, we may deduce from the car's velocity that it will cover 50 kilometers (1 hour) throughout its journey. 

Whether a vehicle begins off traveling slowly and then builds up speed, it doesn't matter if it maintains that pace for the whole hour. That's why, when we say the car's going 50 km/h, we don't ask ourselves whether the car has been traveling at the same speed. Therefore, this is an average speed calculation for the vehicle.

Non-Uniform and Uniform Motions

Non-uniform motion: In ordinary life, we rarely encounter objects traveling at a steady speed across large distances or for lengthy spans of time. If the speed of an object traveling down a straight line constantly changing, its motion is constopicIdered to have non-uniform motion.

Uniform motion: An object in uniform motion is one that travels in a straight path at a constant pace. There is no difference between the average speed and the actual speed in this scenario.

Units of Speed

The speed unit is determined by the units of distance and time.

Distance is often measured in meters, while time is typically measured in seconds. Thus, a meter per second (m/s) is the usual measure or unit of speed or velocity.

In this context, we measure distance in kilometers and time in hours, with high speeds being indicated in kilometers per hour (km/h).

In a given situation, if the distance traveled is denoted in centimeters and the time is given in seconds, the speed is calculated in centimeters per second (cm/s).

If we want to be able to make meaningful comparisons between the speeds of different objects, we need to represent those speeds using the same unit.

Measurement of Time

Time: Time is defined as the period during which an event takes place. Time is often measured using timepieces such as clocks and watches. Since ancient people dtopicIdn't have wristwatches or clocks, it's hard to imagine how they kept track of time.

Ancient peoples recognized that some natural phenomena, like the sun rising daily in the morning, repeated at regular, measurable intervals and employed them as timepieces. 

Day: A day was therefore defined as the interval between successive sunrises. 

Month: A month was defined as the duration between two consecutive full moons.

Year: The length of time it takes for Earth to make one full circle around the Sun was established as one year.

Prior to the wtopicIdespread use of pendulum clocks, other timekeeping methods had been in use around the globe. For instance, sundials, sand clocks, and water clocks all fall under this category.

  Sundial: A sundial uses the angle of the shadow produced by the sun to determine the time of day.

Sand Clock: The term "sand clock" refers to a timepiece that measures the passage of time by monitoring the rate at which sand moves from one glass bulb to another.

Water Clock: A water clock is a gadget that measures time by monitoring the rate at which water drips from one container to another.

FAQ:
Q. How do you find out whether an object is traveling faster than the other?

Ans. The most practical way to determine how fast two objects are traveling is by divtopicIding the distance traveled by them in a unit of time. In other words, you are comparing the distance traveled by both objects in a given time.
