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!

THE MYSTERIOUS OCTAHEDRON

Today's post is more related to mathematics, as you can tell from the title. I'll be telling you about the amazing solid shape, the octahedron. WHAT YOU WILL LEARN TODAY : We will have found- -->The derivation of the formula for the volume of the octahedron. -->The ratio of the volume of an octahedron when placed inside a cube with its vertices touching the centers of the faces of the cube and the volume of the cube. So! Let's begin! You will have to understand platonic solids first. PLATONIC SOLIDS: Platonic solids are five geometric solids that have congruent and regular sides that meet at three-dimensional angles. Plato used them to explain the structure of the universe. Hence, the name 'Platonic'. There are five Platonic solids: the tetrahedron with four faces, the cube with six faces, the octahedron with eight faces, the dodecahedron with twelve faces, and the icosahedron with twenty faces. They are used in many fields, including biomedical rese...

Refraction of Light

You must have heard of reflection of light. It's when a ray of light bounces back from a surface. When a light ray hits a mirror, it bounces back with the same angle as the angle with which it hit the mirror. The angle of incidence is always equal to the angle of reflection But what if instead of a mirror, there is a transparent surface? In such cases, the light ray goes through the surface, and undergoes refraction. What is refraction? Refraction is the bending of light when it goes from one medium to another. This happens because the speed of light changes across two different media. When a ray of light is perpendicular to the normal, it travels to the other medium without bending. The ray of light only bends when it goes obliquely from one medium to another. This bending of light depends on the medium through which light is travelling. Optical Density • Rarer medium: The medium through which the speed of light is more is an optically rarer medium. • Denser medium: The medium...

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 ...
