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.
Testez vos connaissances avec un QCM de 7 questions sur Fundamentals of Scalars and Vectors.
1. How does the vector nature of quantities like force and velocity influence their effects on objects?
2. In a scenario where an object moves along a curved path and returns close to its starting point, which quantity should be used to calculate the total length of the path traveled?
