Informally, dynamics is the study of forces and motion. More formally, dynamics is the branch of mechanics that deals with the effect that forces have on the motion of objects.

This section of The Physics Hypertextbook is a gathering place for problems where the forces are not balanced in one direction.

The branch of mechanics that deals with both motion and forces together is called dynamics and the study of forces in the absence of changes in motion or energy is called statics.

Frequently used equations in physics. Appropriate for secondary school students and higher. Mostly algebra based, some trig, some calculus, some fancy calculus.

In contrast, dynamics is the study of forces and motion; or more formally, the branch of mechanics that deals with the effect that forces have on the motion of objects.

The top moves forward a distance s = 2.5 m, then stops and spins in place. Using rotational dynamics (and kinematics) determine… the moment of inertia I of the top (essentially, the moment of inertia of …

The force needed to stretch or compress a spring is proportional to its change in length. This is known as Hooke's law and it works for many spring-like things.

The Physics Hypertextbook is a reaction to three big problems with textbooks: lack of writer's voice, layouts that reduce readability, and outdated economics.

This section of The Physics Hypertextbook is a gathering place for problems where the forces are balanced in all directions.
