2024 EXPERT CERTIFIED QUESTIONS AND
ANSWERS

,Difference between scalar and vector: - CORRECT
ANSWER--scalar = magnitude only
-vector = direction and magnitude


The only vector quantities are: - CORRECT ANSWER--
acceleration
-velocity
-force
-displacement
-momentum
-weight


Force - CORRECT ANSWER--a push or a pull


Balanced forces - CORRECT ANSWER--when 2 forces
acting on an object are equal in size but act in
opposite direction

,What is Newton's 1st Law? - CORRECT ANSWER--if
forces acting on an object are balanced, the resultant
force is zero
-object at rest, stay stationary
-object moving, continues to move in same direction
and at same speed


What is Newton's 2nd Law? - CORRECT ANSWER--
acceleration is proportional to resultant force
-inversely proportional to mass of object


What is Newton's 3rd Law? - CORRECT ANSWER--two
objects exert equal and opposite forces on each other


Terminal Velocity - CORRECT ANSWER-


Describe the process of terminal velocity - CORRECT
ANSWER--weight acts downwards
-drag acts upwards

, -person accelerated downwards
-eventually weight = drag
-no resultant force, no acceleration, forces are
balanced
-terminal velocity (constant velocity) is reached


If an object gains momentum - CORRECT ANSWER--
increasingly difficult to slow down or change its
direction
-momentum is a vector quantity


Vector Quantity - CORRECT ANSWER--has a
magnitude and a direction


Scalar Quantity - CORRECT ANSWER--magnitude only


Conservation of Momentum - CORRECT ANSWER--as
long as there is no other forces, the total momentum
in an explosion or a collision stays the same
