Edexcel GCSE Triple Science Physics Paper 2
2024 WITH QUESITIONS AND ANSWERS
GRADED A+

,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
