Physics Basic Concepts

This picture explains Momentum and energy

of Distance:
The magnitude or size of displacement between two positions.
:
It is a simple line graph that denotes distance versus time findings on the graph. Distance is plotted on the Y-axis. Time is plotted on the X-axis.
Distance time graph shows how the distance and speed of an object changes with time.

:
Waves can be defined as:
"The disturbance in a medium to transfer energy is called a wave".

Wavelength:
The distance between two successive crests or troughs is called a wavelength.
Its symbol is lambda (λ).

In physics basic concepts today we will study about force.

:
The push or pull on an object with mass causes it to change its velocity.
Force is an external agent capable of changing a body's state of rest or motion. It has a magnitude and a direction.
It is a vector quantity. It has both magnitude and direction.

Mathematical expression:
Mathematically force can be written as:
F=ma
Where m= mass of an object
And a= acceleration
