PHYSICS GCSE PAPER 2 EXAM 2025 SPRING-
SUMMER QUESTIONS AND ANSWERS GRADED
A+
What are vector quantities? give examples
quantities which have a direction and magnitude (size)
force, velocity, displacement, acceleration, momentum
What are scalar quantities? give examples
quantities with only magnitude, no direction
speed, distance, mass, temperature, time
How can vectors be represented?
Using an arrow, the length of it shows the magnitude and the direction shows the
direction of the direction of the quantity
what is a force?
a push or pull on an object caused by it interacting with something
,give examples of contact forces
friction, air resistance, tension and normal contact force
Give examples of non-contact forces
gravitational, electrostatic, magnetic
what is an interaction pair?
A pair of forces that are equal and opposite and act on two interacting object for
example the sun and the earth or a chair on the ground.
a chair exerts force on the ground, the ground exerts the same amount of force on
the chair
gravity is only significant when the masses are really big which means anthing
near a planet/star is attracted to it very strongly. What effects does this have?
1) on the surface of the planet all things fall towards the ground as they are
attracted to the earth
2) it gives everything a weight
what is the difference between mass and weight?
,mass is the amount of matter in an object and so mass will be the same anywhere
in the world whereas weight is the force acting on an object due to gravity. This
force is caused by gravitational fields which vary with location. (eg on earth gfs is
9.8)
how is weight measured?
Using a calibrated spring-balance (a newtonmeter)
what is the centre of mass?
a single point that the force acts on
what is the formula for weight?
Mass(kg) x gravitational field strength (N/kg)
What are free body diagrams? give an example
Diagrams that show all the forces acting on an object
-each force is represented by an arrow
a skydivers weight acts on hum pulling him towards the ground and drag (air
resistance) also acts on him in the opposite direction
, what is a resultant force?
in most situations there are at least 2 forces acting on an object however this can be
replaced by a single force that has the same effect as all the other forces this force
is the resultant force
it shows the overall force
what happens when a force moves an object through a distance?
energy is transferred and work is done on the object
what is the formula for work done? how do you convert joules to newton metres?
Work done (J) = force (N) x distance (m)
W=Fs
1J = 1Nm
what are scale drawings and how do you do them?
-another way to find the resultant force
1) draw out all the acting forces
2) draw a straight line from the start of the first force to the end of the last force
(tip to tail)
3) this is the reultant force
