Missed lesson

Missed lessons: it is your responsibility to catch up with the work before the next lesson. This is in the school rules. It is also really important if you want to have all the work for tests. You will not get any sympathy or test concessions if you do not catch up as the resources are here !

 If you need help, contact me here.

Catch Up

This page includes work you need to cover if you have missed aspects of Physics due to studying outside of the Finnish curriculum.  The work is based around the 'Target Science Physics, Foundation Tier' book by Stephen Pople.

The Finnish curriculum covers:

Waves and Heat in Grade 7

Forces and Motion in Grade 8

Electricity and Nature's Structures (Astronomy and atomic physics) in Grade 9

To catch up the work, complete the tasks as show for each section. There will be an assessment of the work you have done - talk to Karin about the nature of this assessment.

If you have any problems please contact karin    karin DOT parker  (AT) eduouka DOT fi

Forces and Motion Grade 8


8 - Forces and Movement



Topic

Pages in ‘Target Science’ book

What you should learn

Additional information or resources - many of these are links to videos or animations

Task to complete

Speed, velocity and acceleration

p.54.55

How to calculate speed, and what units to use

The difference between speed and velocity

Changing units from m/s to km/h and vice versa

Questions 1-2

Forces and gravity 

P. 60 -61

What a force is and how it is measured.

Gravity causes weight

Weight and mass are different things . weight is a measure of gravity on an object and is measured in newtons. Mass is measured in kg and relates to how much material is in an object


Weight = mass x g

G is the gravitational field strength or acceleration due to gravity. On Earth it is 9.8 N/kg  or  9.8 m/s2

Questions 1-4

Friction and balanced forces

p.62.65

Friction is a force which stops or tries to stop motion.

Friction is caused by forces from particles as surfaces rub together

Friction is also called drag or resistance

All objects, no matter what their mass, fall at the same rate to Earth (Galileo’s experiment) but air resistance will slow them.

When falling, air resistance will slow down an object until terminal velocity is reached.

The amount of air resistance will depend on velocity and surface area.

When all forces are balanced on an object, its speed will not change.

Sky diver and forces from freefall

P. 62 q 1-2

P65 q 1-2




Task: explain why a hammer and feather will fall  to the surface of the Moon at the same time, but not on Earth.

Unbalanced forces

P 66-67

Forces are represented by arrows with size and direction

Resultant forces cause acceleration and direction change

Q 1-3

Balance and centre of mass

P 73

All objects have a point called the centre of mass which is at the point of average distribution of the total mass. To balance, the centre of mass must be above an area of contact with the ground.

What is centre of mass? very short video


Stable, unstable and neutral equilibrium video (ball, pencil)


Fosbury Flop Ted-Ed video


Conservation of energy

P.148 - 151

Energy never disappears, it just changes form.

When an object falls, its gravitational potential energy turns to kinetic energy

Work in physics is done when energy changes form eg when a force moves an object

Conservation of energy video   


Rollercoasters and energy video

P.148 q 1-3

P 149 q 4

P150 q 1-2

P151 q 3-7

Weightlessness and g forces

P 80-81

We feel ‘g-forces’ when we are accelerated

We live in a world of 1-g on Earth. We feel weight because of the force of gravity pulling us down and the force of the floor pulling us up

When we fall we feel weightless as there is no floor to push us up

Astronauts orbiting the Earth are NOT weightless, they simply fall to the Earth at the same rate as their spacecraft so there is nothing pushing back on them
