Speed, Distance and Time | How are they related?

Speed, distance and time are very essential concepts when one starts to learn about physics. Talking about one of them naturally brings up the other two as well, since they are linked with each other. Let's find out how, and learn about them! 


SPEED
Speed is a measure of how fast something is moving. It is how quickly an object is changing it's position, and so, it is a scalar quantity. 

• The speed of an object is said to be more when it is travelling faster and covers more distance in a certain time.

• The speed of the object is said to be less when it is travelling slower and covers lesser distance in the same time.

SI unit of speed:
• m/s (metres  per second)
• Commonly used : Km/h (Kilometres per hour)
• m/h (miles per hour)

How to calculate speed:
speed = distance/ time


DISTANCE
The distance between two objects is a measure how far away the objects are from each other. It is the physical length between two objects.

• The distance between two objects is said to be more if the objects are far from each other.

• The distance between two objects is said to be less if the objects are close to each other.

SI unit of distance:
• m (metres)
• km (kilometres)

How to calculate distance:
distance = speed × time


TIME
Time is the ongoing sequence of events in the past, present and future. Time can be known by looking at a clock. It is never ending, and it keeps going.

• The time taken by an object to travel a certain distance is more if it travels at a lower speed.

• The time taken by an object to travel a certain distance is less if it travels at a higher speed.

SI unit of time:
• minutes
• hours
• seconds

How to calculate time:
time = distance/ speed


And there you go! Now you understand the relationship between Speed, distance and time!

Special Relativity Explained

Hello everyone! Have you ever heard about Special relativity?Its a remarkable theory published by the well known physicist Albert Einstein.I am sure you must have heard of him. Now lets know a bit more about special relativity. Special Relativity is the  accepted and  well-confirmed physical theory regarding the relationship between space and time or space-time. In Albert Einstein's original pedagogical treatment, it is based on two postulates.They are: 1.the laws of physics are invariant in all inertial systems / non-accelerating frames of reference. 2.the speed of light in a vacuum is the same for everyone, regardless of the motion of the source of the light. Special relativity is the most accurate model of motion at any speed when gravitational effects are negligible. But still, the Newtonian mechanics model is valid as a simple and high accuracy approximation at low velocities relative to the speed of light(c). Special relativity implie...

General Relativity Explained

Have you ever heard about General relativity?  General relativity is a remarkable theory published by the well known physicist Albert Einstein. Let us know more about general relativity. General relativity is the geometric theory of gravitation published by Albert Einstein. Albert Einstein published this theory in 1915. It is the current description of gravitation in modern physics. General relativity generalizes special relativity and Newton's law of universal gravitation , and gives a unified description of gravity as a geometric property of space and time, or space-time . THE CURVATURE OF SPACE-TIME AND THE EINSTEIN FIELD EQUATIONS The  curvature of space-time is directly related to the energy and momentum of whatever matter and radiation are present. The relation is specified by the Einstein field equations. That is a system of partial differential equations. The Einstein field equations comprise a set of 10 equations in Albert Einstein's general theory of ...
