Question

how is dynamics related to physics? answer urgently please!

Answer 1

Dynamics. Dynamics, branch of physical science and subdivision of mechanics that is concerned with the motion of material objects in relation to the physical factors that affect them: force, mass, momentum, energy. ... This law states that the force acting on a body is equal to the rate of change of the body's momentum.

Answer 2

Dynamics is the branch of applied mathematics (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 can be subdivided into kinematics, which describes motion, without regard to its causes, in terms of position, velocity, and acceleration; and kinetics, which is concerned with the effect of forces and torques on the motion of bodies having mass.
