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 |
Ek
= 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 |
Ep = m x g x
h
|

find velocity for a falling object.

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. |
