Mechanics - Statics and Dynamics

Question 1

Newton’s First Law (Inertia Law)

Answer 1

Newton’s First Law (Inertia Law)

Question 2

Newton’s Second Law (Acceleration Law)

Answer 2

When experiencing an external resultant force, the acceleration vector of a body is directly proportional to that of the applied force (ΣF = ma).

Question 3

Newton’s Third Law (Reciprocity Law)

Answer 3

When body A exerts a force on body B, body B exerts a force of equal magnitude in the opposite direction on body A. [✸ type/of/on ✸]

Question 4

Newton’s Third Law Criteria

Answer 4

(1) equal magnitude but opposite direction; (2) same line of action; (3) same type; (4) same duration; (5) on different bodies.

Question 5

Resultant Force (ΣF)

Answer 5

newtons [N] + direction

Question 6

Mass (m)

Answer 6

kilograms [kg]

Question 7

Acceleration (a)

Answer 7

metres per second squared [m s-2] + direction
