AQA GCSE PHYSICS PAPER 2 COMPLETE
STUDY GUIDE QUESTIONS AND VERIFIED
ANSWERS
●● What are scalars?
Answer: Quantities that only have a magnitude
●● Examples of vectors
Answer: Force
Velocity
Displacement
Acceleration
Momentum
●● Examples of scalars
Answer: Speed
Distance
Mass
Temperature
Time
,●● What are contact forces?
Answer: Forces that act when two objects are touching
●● What are non-contact forces?
Answer: Forces that act without the need for two objects to be touching
●● Examples of contact forces
Answer: Friction
Air resistance
Tension in ropes
Normal contact force
●● Examples of non-contact forces
Answer: Magnetic force
Gravitational force
Electrostatic force
●● What is mass?
Answer: The amount of material an object is made of
It is the same value everywhere
Measured using a mass balance
,●● What is weight?
Answer: The force acting on an object due to gravity
It depends on the strength of the gravitational field at the location of the
object
Measured using a calibrated spring balance - newtonmeter
●● Equation for Weight
Answer: Weight (N) = Mass (kg) x Gravitational Field Strength (N/kg)
W=mg
●● What is weight directly proportional to?
Answer: Mass
●● What are free body diagrams?
Answer: Diagrams that show all the forces acting on an object
●● What is the minimum number of forces acting on an object in real
situations?
Answer: At least 2 forces
●● What is the resultant force?
Answer: The single force that replaces multiple forces acting at a single
point
, ●● How is work done?
Answer: When a force moves an object through a distance, energy is
transferred and work is done on the object
●● Equation for 'Work Done'
Answer: Work done (J) = Force (N) x Distance (m)
W=Fs
●● What is 1J equal to?
Answer: 1Nm
●● What could happen when you apply a force to an object?
Answer: It may stretch, compress or bend
●● What happens when an object is inelastically deformed?
Answer: The object won't return to its original shape and length after the
force has been removed
●● Equation for Force 1
Answer: Force (N) = Spring Constant (N/m) x Extension (m)
F=ke
