Notes 
1 
Work done 
W = F x d 

2  Power

Know that power is a measure of the rate at
which energy is transferred.
Be able
to solve numerical problems involving energy and power using the
equation
Power = work done
ś time taken
or Power = energy
transferred ś time taken 

3 
Kinetic energy 
E_{k}
= œ x m x vČ

For Higher tier
classes  calculations of GPE and KE, including rearranging to
find velocity for a falling object.
Foundation classes
can still cover the ideas qualitatively  Catapult practical is
straightforward and reasonably entertaining. 
4  Gravitational
potential energy 
E_{p} = m x g x
h

For Higher tier
classes  calculations of GPE and KE, including rearranging to
find velocity for a falling object.
Foundation classes
can still cover the ideas qualitatively  Catapult practical is
straightforward and reasonably entertaining. 
5  Momentum I

Know that all massive objects have momentum when in
motion.
Be able to calculate the momentum of a moving object
using the formula p = m Ś v
Be able to find the change in momentum of an object,
given information about its velocity.


5  Momentum II 
Know that momentum is conserved in a closed system.
Be able to apply the law of conservation of momentum
to determine the outcome of collision or explosion events.


7
Physics of
transport 

discuss crumple
zones and airbags in terms of time taken to come to rest
increasing which reduces average force, and also in terms of
work done over a larger distance  again reducing average force.
