Bangla Note of Physics 1st paper for HSC
Gravitation, or gravity, is a natural phenomenon by which all physical bodies attract each other. It is most commonly recognized and experienced as the agent that gives weight to physical objects and causes physical objects to fall toward the ground when dropped from a height.

In physics, euclidean vectors are used to represent physical quantities that have both magnitude and direction, such as force, in contrast to scalar quantities, which have no direction. Mathematics Solution of … Read more
Last Updated: March 19, 2026 at 9:32 pmDynamics is a branch of physics (specifically classical mechanics) concerned with the study of forces and torques and their effect on motion, as opposed to kinematics, which studies the motion of objects without reference to its causes. Dynamics Details with Diagram Generally speaking, researchers involved in dynamics study how a physical system might develop or … Read more
Last Updated: March 19, 2026 at 9:32 pmWork: Work refers to an activity involving a force and movement in the directon of the force. A force of 20 newtons pushing an object 5 meters in the direction of the force does 100 joules of work. Energy: Energy is the capacity for doing work. You must have energy to accomplish work – it … Read more

Last Updated: March 19, 2026 at 11:48 pmPhysics linear motion is motion along a straight line, and can therefore be described mathematically using only one spatial dimension. The linear motion can be of two types: uniform linear motion with constant velocity or zero acceleration; non uniform linear motion with variable velocity or non-zero acceleration. The motion of a particle along a line … Read more

Last Updated: March 19, 2026 at 11:48 pmMotion in Two Dimensions Galileo was the first to realize that a moving body can have several separate motions, which are independent of each other. His thinking provides a foundation for Newton’s treatment of acceleration and force. A body moving at constant velocity can be described by a sum of velocities in two directions, typically … Read more
