Physics paper 2 foundation EXAM QUESTIONS WITH CORRECT VERIFIED ANSWERS|GRADE
A+ GUARANTEED|100% PASS ASSURED
Scalar quantities - CORRECT ANSWER -Only have magnitude
Vector quantities - CORRECT ANSWER -Have magnitude and direction (represented with
arrows)
Force - CORRECT ANSWER -Push or pull that acts on an object due to an interaction with
another object
Contact force - CORRECT ANSWER -Objects are physically touching
Examples of contact forces - CORRECT ANSWER -Friction, air resistance, tension and
normal contact force
Non-contact force - CORRECT ANSWER -The objects are physically separated
Examples of non-contact forces - CORRECT ANSWER -Gravitational, electrostatic and
magnetic force
Weight - CORRECT ANSWER -Force acting on an object due to force. It depends on the
gravitational field strength
Unit for weight - CORRECT ANSWER -Newtons (N)
, Unit for mass - CORRECT ANSWER -Kilogram (kg)
Unit for gravitational field strength - CORRECT ANSWER -Newtons per kilogram (N/kg)
Resultant force - CORRECT ANSWER -An overall force on an object that takes into
account all the forces acting on an object in different directions
If there is a resultant force acting on an object what does that mean? - CORRECT
ANSWER -Object is accelerating or decelerating
If there is no resultant force on an object what does that mean? - CORRECT ANSWER -
Object is moving at a constant speed or is stationary
Work done - CORRECT ANSWER -Energy transferred
Conversion of Joules to Newton-metres - CORRECT ANSWER -1 Joule = 1 Newton-metre
Why is there forces acting in at least 2 directions when changing the shape of an object
(stretching, compressing etc) ? - CORRECT ANSWER -As the ball remains stationary so
the resultant force is zero
Elastic deformation - CORRECT ANSWER -Region where the material will return to its
original shape when the stress is removed
Plastic deformation - CORRECT ANSWER -Permanent deformation caused by strain when
stress exceeds a certain value
Displacement - CORRECT ANSWER -How far an object is away from where it started (+ or
-)
