AQA GCSE COMBINED
SCIENCE PHYSICS - PAPER 2
1. Vector quantities - CORRECT ANSWER -have magnitude and direction
2. Examples of vector quantities - CORRECT ANSWER -force, velocity, momentum,
acceleration
3. Scalar quantities - CORRECT ANSWER -Only have magnitude and no direction
4. Examples of scalar quantities - CORRECT ANSWER -speed, distance, time
5. Vectors - CORRECT ANSWER -represented by an arrow - the length of the arrow
shows the magnitude. The direction of the arrow shows the direction of the quantity
6. A force is - CORRECT ANSWER -a push or pull on an object that is caused by it
interacting with something
7. when two objects are touching for the force to act, its a .... - CORRECT ANSWER
-contact force
8. examples of contact forces - CORRECT ANSWER -friction, air resistance, tension
in ropes. etc
9. If the objects do not need to be touching for the force to act, the force is a ...... -
CORRECT ANSWER -non contact force
,10. examples of non contact forces - CORRECT ANSWER -magnetic force and
gravitational force
11. Two effects of gravity - CORRECT ANSWER -- makes all things fall towards the
ground
- gives everything a weight
12. What is mass? - CORRECT ANSWER -The amount of material an object is made
of
13. It is the same value everywhere
14. Measured using a mass balance
15. What is weight? - CORRECT ANSWER -The force acting on an object due to
gravity
16. It depends on the strength of the gravitational field at the location of the object
17. Measured using a calibrated spring balance - newtonmeter
18. Equation for Weight - CORRECT ANSWER -Weight (N) = Mass (kg) x Gravitational
Field Strength (N/kg)
19. W=mg
20. What is weight directly proportional to? - CORRECT ANSWER -mass
21. What are free body diagrams? - CORRECT ANSWER -Diagrams that show all the
forces acting on an object
22. What is the resultant force? - CORRECT ANSWER -The single force that replaces
multiple forces acting at a single point
, 23. How is work done? - CORRECT ANSWER -When a force moves an object through
a distance, energy is transferred and work is done on the object
24. Equation for 'Work Done' - CORRECT ANSWER -Work done (J) = Force (N) x
Distance (m)
25. W=Fs
26. What is 1J equal to? - CORRECT ANSWER -1Nm
27. If all the forces acting on an object combine to give a resultant force of zero then the
object is in ? - CORRECT ANSWER -equilibrium
28. What could happen when you apply a force to an object? - CORRECT ANSWER -
It may stretch, compress or bend
29. What happens when an object is elastically deformed - CORRECT ANSWER -The
object can go back to its original shape and length after the force has been removed
30. What happens when an object is inelastically deformed? - CORRECT ANSWER -
The object won't return to its original shape and length after the force has been
removed
31. Equation for Force 1 - CORRECT ANSWER -Force (N) = Spring Constant (N/m) x
Extension (m)
32. F=ke
33. Extension is directly proportional to? (Hooke's Law) - CORRECT ANSWER -The
force applied
34. F∝e
