Physics - Paper 2 Exam Questions
With 100% Pass
/. Vector quantities - Answer-have magnitude and direction
/.Examples of vector quantities - Answer-force, velocity, momentum, acceleration
/.Scalar quantities - Answer-Only have magnitude and no direction
/.Examples of scalar quantities - Answer-speed, distance, time
/.Vectors - Answer-represented by an arrow - the length of the arrow shows the
magnitude. The direction of the arrow shows the direction of the quantity
/.A force is - Answer-a push or pull on an object that is caused by it interacting with
something
/.when two objects are touching for the force to act, its a .... - Answer-contact force
/.examples of contact forces - Answer-friction, air resistance, tension in ropes. etc
/.If the objects do not need to be touching for the force to act, the force is a ...... -
Answer-non contact force
/.examples of non contact forces - Answer-magnetic force and gravitational force
/.Two effects of gravity - Answer-- makes all things fall towards the ground
- gives everything a weight
/.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 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
/.If all the forces acting on an object combine to give a resultant force of zero then the
object is in ? - Answer-equilibrium
/.What could happen when you apply a force to an object? - Answer-It may stretch,
compress or bend
/.What happens when an object is elastically deformed - Answer-The object can go
back to its original shape and length after the force has been removed
/.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
/.Extension is directly proportional to? (Hooke's Law) - Answer-The force applied
F∝e
/.What is the limit of proportionality? - Answer-The point at which extension is no longer
directly proportional to force
/.Practical: Investigating the link between force and extension - Answer-- First, measure
the original length of the spring using a milimetre ruler
- Next, add different masses on the spring and measure the length of the spring in each
case.
- The extension = change in length
- Repeat this process until you have enough measurements ( no fewer than 6)
- Plot a graph with extension of the spring on the x axis and force on the y axis.
- The graph will only start to curve if you exceed the limit of proportionality
