mass

 mass
(physics) The quantity of matter which a body contains, irrespective of its bulk or volume. It is one of four fundamental properties of matter. It is measured in kilograms in the SI system of measurement.

free body diagram

  free body diagram
A free body diagram is a pictorial representation often used by physicists and engineers to analyze the forces acting on a free body. It shows all contact and non-contact forces acting on the body. Drawing such a diagram can aid in solving for the unknown forces or the equations of motion of the body.

equilibrium

 equilibrium
(physics) The state of a body at rest or in uniform motion in which the resultant of all forces on it is zero.

slope

 slope
  1. (mathematics) The ratio of the vertical and horizontal distances between two points on a line; zero if the line is horizontal, infinite if it is vertical. The slope of this line is 0.5.
  2. (mathematics) The slope of the line tangent to a curve at a given point. The slope of a parabola increases linearly with x.
