Force:

แปลว่า(english) A directed interaction between two objects that tends to change the momentum of both.Since a force has both direction and magnitude, it can be expressed as a vector

Vector:

แปลว่า(english) A mathematical entity having a magnitude and a direction in space.

Inertial Force:

แปลว่า(english) A fictitious force used for convenience in visualizing the effects of forces on bodies in motion. For an accelerating body, the inertial force is considered as a body force whose resultant acts at the object's center of gravity in a direction opposite the acceleration. The magnitude of the force is the mass of the object times the magnitude of the acceleration.

Couple:

แปลว่า(english) A system of forces composed of two equal forces of opposite direction, offset by a distance. A couple is statically equivalent to a moment whose magnitude equals the magnitude of the force times the offset distance.

Magnitude:

แปลว่า(english) A scalar value having physical units.

Kinetic Energy:

แปลว่า(english) The energy of a moving mass; equal to (mv^2)2. Where m is mass and v is the magnitude of the velocity.

magnitude

แปลว่าขนาด, ปริมาณ

Equilibrium:

แปลว่า(english) An object is in equilibrium if the resultant of the system of forces acting on it has zero magnitude. See static equilibrium and dynamic equilibrium.

Resultant:

แปลว่า(english) The resultant of a system of forces is a single force or moment whose magnitude, direction, and location make it statically equivalent to the system of forces.

magnitude

แปลว่าขนาดใหญ่, ความใหญ่ (ของขนาดหรือปริมาณ)

order of magnitude

แปลว่าลำดับความสำคัญ

Rotation:

แปลว่า(english) Motion of an object where the path of every point is a circle or circular arc. A rotation is defined by a point and vector which determine the axis of rotation. The direction of the vector is the direction of the axis and the magnitude of the vector is the angle of rotation.
