Physics

Described by magnitude only e.g: mass, time, distance, speed, and temperature

Scalar Quantities

Require both magnitude and direction e.g: velocity, force, acceleration, and displacement

Vector Quantities

A combination of horizontal and vertical motion

Projectile Motion

Motion that is not affected by gravity

Horizontal Motion

Motion that is affected by gravity

Vertical Motion

One of the laws of motion when an object is at rest remains at rest and an object in motion remains in motion in a straight line with constant speed unless acted upon by external, unbalanced force

Law of Inertia

One of the laws of motion when force is directly proportional to mass and acceleration

Law of Acceleration

One of the laws of motion that for every action, there is an equal and opposite reaction

Law of Action Reaction

It occurs when the two things come into contact directly

Contact Force

The resistance of an object when its surface is directly rubbing the other’s surface

Friction

Type of friction where there are no relative motion between the two bodies

Static Friction

Type of friction where there are friction that opposes an object to slide

Kinetic Friction

Type of friction where it exist in a rolling motion

Rolling Friction

A motion of an object in a circular path at a constant speed.

Uniform Circular Motion

It occurs when an object’s fields interact with another object’s fields and the objects are not directly touching

Non-contact Force

Type of Non-contact Force where it involves the gravitational field around any mass

Gravitational Force

Type of Non-contact Force where it involves the electric field of one charged body and another

Electrostatic Force

Type of Non-contact Force where there is interaction between magnetic fields

Magnetic Force

Everything pulls on everything else with a force that depends on the masses of the objects and the distance between them

Law of Universal Gravtitation

The energy of a moving object

Kinetic Energy

Type of kinetic energy that is the movement of electrical charges through wire

Electrical Energy

Type of kinetic energy where the movement of objects from one place to another when force is applied

Mechanical Energy

Type of kinetic energy where there is vibration and movement in moving particles in substances

Thermal Enegy

Type of kinetic energy where electromagnetic energy travels in waves

Radiant Energy

The energy is at rest

Potential Energy

Type of potential energy where the energy stored in atoms and molecules and holds all particles together

Chemical energy

Type of potential energy where the energy in a position is done on the object against gravity

Gravitational energy

Type of potential energy where the energy is close to being kinetic mechanical energy

Stored mechanical energy

It passes through transparent things, sort of passes through translucent things and cannot pass through opaque things

Light

It is produced when a force causes an object to vibrate

Sound

Transfers to particles through kinetic energy by bouncing off each other

Heat

Heat transfer method through direct contact, solids usually metals

Conduction

Heat transfer method through liquids and gases

Convection

Heat transfer method through vacuum, electromagnetic wave and doesn’t require a medium to travel through

Radiaton

The measure of energy transfer that occurs when an object is moved over a distance by an external force

Work

Momentum remains constant if not added upon by an external force

Law of Conservation of Momentum

Forceful and sudden interaction of 2 bodies that alters their momentum, example of conservation of momentum,

Collision

Type of collision when objects move separately when the collide

Elastic Collision

Type of collision when the objects bounce off each other without any loss of kinetic energy

Perfectly Elastic Collision

Type of collision when the objects move together as a single combined mass after collision

Perfectly Inelastic Collision

Rate of flow of charges

Current

Opposition to the flow of charges

Resistance

Potential difference that causes charges to flow

Voltage

The current share only one path, if one dies, the rest follows. It is dependent

Series Circuit

The current can have more than one path or branch, if one dies, the rest doesn’t, It is independent

Parallel Circuit

A disturbance that transfer energy through a medium w/o permanently changing the particles

Wave

Bouncing of a wave from a surface

Reflection

Waves bending from one medium to another

Reflection

Spreading of waves around obstacles

Diffraction

Two or more waves meet while travelling at the same direction

Interference

Lens that is thicker at the center, it converges light rays. It forms real images

Convex Lens

Lens that is thinner at the center, it diverges light rays. It forms virtual and erect images

Concave Lens
