physics dynamics

Kinematics

The study of motion without considering the forces that cause it.

Dynamics

The study of forces and their impact on motion.

Thermodynamics

The branch of physics that deals with heat and temperature and their relation to energy and work.

Newton's First Law

An object at rest will remain at rest, and an object in motion will continue in motion at constant velocity unless acted upon by a net external force.

Newton's Second Law

The acceleration of an object is inversely proportional to its mass and directly proportional to the net force applied.

Newton's Third Law

For every action, there is an equal and opposite reaction.

Friction

Resistance that occurs when an object slides against other objects, opposite to the direction of motion.

Static Friction

The type of friction that occurs when an object is not moving, preventing motion.

Kinetic Friction

The type of friction that occurs when objects are in motion and rubbing against each other.

Weight

The gravitational force acting on an object.

Scale

Measures the normal force exerted by an object, reflecting action-reaction forces.

Tension Force

The force applied by a string, directed along the string towards the pull.
