1. Sharmin, Maria, Fozia and Zanab

2. Where are we going?
Acker’s Adventure
(Sparkbrook).
What are we doing?
Canoeing
Why are we going?
To have fun learning
physics!!!

3.  Consent form, Medical/ emergency contact
 Suitable clothes: Waterproof clothing,
footwear with grip, no jewellery, no valuables
 Risk assessment- life jackets
 Need a trained first aider (School Staff).
 Staff: Student = approx. 1:5

5. Key word Basic Definition
Force Pushing or pulling action, resulting in
movement: F= ma
Mass Measured in grams/ kg
Weight Vertical force of an object, Measured in All related to
Newtons W= mg
the motion,
Acceleration The rate at which velocity increases a=V/t
(m/s2)
speed and
potential of the
Energy The ability to make things happen. Measured
in Joules. canoe.
Speed How fast an object is travelling s= d/t
Velocity Speed + direction
Newton’s Laws 1st, 2nd, 3rd
of motion

6. How will
having more
Name the weight
forces effect the
boat?
Where is the
energy
How can we
coming
work out
from? What keeps the velocity?
the boat
floating?

7.  Difference between stationary and moving
Stationary In Motion

8.  Newton (b.1643) (father prosperous farmer). Difficult man,
prone to depression, often involved in bitter arguments with
other scientists. Lived to his eighties (no spectacles)!
Experimented on himself:
-Pressure experiments by applying needle to eyes
(effect on colour vision of the curvature of the
orbit).
-Light and its properties. Experimented with way we
see (relationship between light, colour
and optics). Almost blind looking for long periods
directly into sun while observing coloured rings.
(Dark room)?
Apple story: Reports suggest apple did not fall on his head (Stukeley in his
Memoirs1726). Concluded: Force which caused apple to fall to Earth also kept
moon in orbit around Earth and planets in orbit around sun (basic laws of
motion used to date).

9.  Upthrust- When canoe is in water, a volume of water is
displaced so upthrust is equal to volume of water
(demo).
 Newton’s 1st law: If no resultant force acting on object,
will remain at rest. If it’s moving, will continue to move
with a constant velocity in straight line.
 Newton’s 3rd law : To every action there is an opposite
and equal reaction- 2 objects involved- canoe, water.
Upthrust from the water and the weight are equal and
opposite forces. There’s no resultant vertical force so
canoe does not sink.

10.  What will happen if there are more people in the
canoe?
Increase in mass, therefore increase in
weight.
If an unbalanced force acts on the object it
will either accelerate or decelerate.

11. Another example of an unbalanced force…
Canoe will move in 3rd direction- spin!

12.  Energy transfers-
Potential
Chemical
Kinetic
 http://www.youtube.com/watch?v=4Ss2QX4p_Ts
 Energy transfers (1)
 More people rowing (faster) (2)
 Moments (3)

13.  Observe different speeds by changing the
mass in the boat.
 What does mass affect? Force sizes/ speed

14. How does increasing the mass
Mass (g) Time (s) 14
affect the time taken?

Distance travelled: 79cm
As you can see, the putt boat with less mass in
it, has travelled the furthest and fastest.
As for the heaviest mass, the mass in the boat,
decreased its speed.

15.  Speed = distance/time
