The physical quantities which can be treated as independent of other physical quantities are called

The physical quantities whose defining operations are based on other physical quantities, are called

Quantities that are described by their magnitude ONLY

Quantities that are described by their magnitude AND direction.

It is a scalar quantity that refers to "how much ground an object has covered" during its motion.

It is a vector quantity that refers t o "how far out of place an object is“ It is the object's overall change in position.

Resultant is a vector sum of more than one vector. It is combining vectors having different magnitude and direction. It is represented by one single vector called resultant vector.

is any substance that has mass and takes up space by having volume.

is the quantitative property that must be transferred to an object to perform work.

The study of forces acting on bodies whether at rest or at motion.

It studies the production and properties of sounds

The study of the relationship between heat and other forms of energy.

The study of the nature and behavior of light.

The study of the properties of electric current and magnetism and their relationship.

The study of the discrete nature of phenomena at the atomic and subatomic levels its focus is on the invisible units of energy called quanta.

The study of the components, structure and behavior of the nucleus of the atom.

The study of the phenomena that takes place in a forms of reference that is in motion with respect to an observer.

The study of all properties of solid materials including electrical conduction in crystals of semi-conduction and metals.

The study of highly ionized gases that is, gases that have been separated into positively and negatively charged particles.

BRANCHES OF PHYSICS Modern (post-1900)

an object is in motion if it change position relative to a reference point.

is the science of describing the motion of an object quantitatively.

“How fast something is moving.”

“It is the speed with direction.”

ACCELERATES IN THE DIRECTION IT IS MOVING

ACCELERATES IN THE OPPOSITE DIRECTION TO ITS MOVEMENT (SLOWS DOWN)

An object falling without air resistance or friction is defined to be in

opposes the motion of an object through the air

opposes motion between two objects.
