1.01 use the following units: kilogram (kg), metre (m), metre/second (m/s), metre/second^2(m/s^2), newton (N), second (s) and newton/kilogram(N/kg)

Make sure you are familiar with units for 

Mass: kilogram (kg)

Distance: metre (m)

Speed: metre per second (m/s)

Acceleration: metre per second squared (m/s^2)

Force: newton (N)

Time: second (s) 

Gravity: newton/kilogram (N/kg) 


1.11 describe the effects of forces between bodies such as changes in speed, shape or direction

Forces can act on a body to change the velocity, so the speed, direction or both.

Or forces can change the shape of a body, stretching it squishing it or twisting it. 

1.12 identify different types of force such as gravitational or electrostatic

different types of forces include:

Gravitational, weight, friction, electrostatic, air resistance (drag), tension (force in a spring), up thrust, lift, thrust 

1.13 understand how vector quantities differ from scalar quantities

scalars are quantities with only magnitude (size)

vectors are quantities with magnitude (size) and direction 

1.14 understand that force is a vector quantity

Force has a magnitude measured in (N) but it also has a direction, a push or a pull, up, down, left or right. So force is a vector.  

1.17 know and use the relationship between unbalanced force, mass and acceleration : F = M x A

Force = Mass x Acceleration.

the force refers to the resultant force or the combined forces as seen in 1.15 

1.21 describe the forces acting on falling objects (explain why falling objects reach a terminal velocity)

Initially the only force is weight as drag is proportional to velocity. So the object accelerates downwards. As it accelerates the velocity so the drag increases as well. meaning there is a smaller resultant force downwards so a smaller acceleration. Until the object reaches a speed where the drag is equal to the weight meaning there is no acceleration, this velocity is know as terminal velocity. 

4.03 use the principle of conservation of energy

In any process energy is never created or destroyed. (It is just transferred from one store to another.)

4.11 know and use the relationship between work done, force and distance moved in the direction of the force: W = F × d

Work Done (J) = Force (N) x distance moved (m) 

4.12 know that work done is equal to energy transferred

Work done = energy transferred

4.16 describe power as the rate of transfer of energy or the rate of doing work

power is the rate of transfer of energy, or the rate of work done. so p = E/t 

4.17 use the relationship between power, work done (energy transferred) and time taken:
