Parabolic Motion

Is when an object has two dimensions: U.R.M on the horizontal axis and U.A.R.M on the vertical axis.

Vertical Motion

Is when we throw an object totally up, meaning that the initial velocity or force is only applied in the vertical axis.

Uniform Rectilinear Motion (U.R.M)

Is when an object travels in a straight line at a constant speed with zero acceleration.

Uniformly Accelerated Rectilinear Motion (U.A.R.M)

Is when an object travels in a straight line with constant acceleration.


Property of objects to maintain their current state.

Law of Conservation of Matter

Energy is neither created nor destroyed, only transformed.

Gravitational Acceleration

Type of acceleration that attracts bodies towards the center of an astro.


Scalar magnitude produced when a force moves a body in the same direction it is applied.


Capacity to perform work.


Type of force that is the action of gravity on the mass of a body.


Acceleration on the mass of an object to achieve movement.


Speed at which work can be performed.


Force that opposes movement.

The Law of Gravitation

States that any particle of matter in the universe attracts any other with a force varying directly as the masses and inversely as the square of the distance between them.

The Law of Ellipses

Explains that planets orbit the sun in a path described as an ellipse.

The Law of Equal Areas

Describes the speed at which any given planet will move while orbiting the sun. The speed at which any planet moves through space is constantly changing.

The Law of Harmonies

Compares the orbital period and radius of orbit of a planet to those of other planets. The comparison being made is that the ratio of the squares of the periods to the cubes of their average distances from the sun is the same for every one of the planets.
