Karteikarten: Fundamentals of Scalars and Vectors — 14 Karten

Scalar quantities — definition?

Quantities with only magnitude, no direction.

Vector quantities — role?

Have both magnitude and direction, e.g., force.

Position — what?

Object’s location relative to a reference point.

Displacement — difference?

Change in position; shortest straight-line vector.

Distance — nature?

Total length traveled; scalar quantity.

Speed — type?

Scalar rate of distance covered over time.

Velocity — how?

Vector rate of change of displacement.

Vector addition — method?

Head-to-tail graphical or component-wise calculation.

Resultant vector — meaning?

Single vector representing combined effect of multiple vectors.

Force — what?

Push or pull acting on an object (vector).

Free-body diagram — purpose?

Visualize all forces acting on an object.

Equilibrium — condition?

Net force zero; object at rest or constant velocity.

Inclined plane forces — resolve?

Into components parallel and perpendicular to slope.

Normal force — acts?

Perpendicular to contact surface, balancing perpendicular forces.
