• Scalars and Vectors [FREE] - These quantities both have a size, but vectors also have a direction

​

• Forces [FREE] - Something that acts on an object due to its interaction with another object

​

• Resultant Force [FREE] - This is the overall force that acts on an object

​

• Free Body Diagrams - These allow us to clearly see all the forces acting on an object 

​

• Resolving and Adding Forces - Both graphically and mathematically 

​

•  Work Done - Work is done when a force causes an object to move a distance 

​

• Springs - Stretching, bending and compressing elastic and inelastic objects

​

•  Moments  - The turning effect of a force

​

•   Gears  - These transmit the rotational effect of a force 

​

•  Pressure  - In fluids this causes a force at right angles to a surface

​

​

•  The Earth's Atmosphere  - The thin layer of air that surrounds the Earth

​

•  Distance [FREE] - How far something moves, and how this is related to displacement  

​

• Speed [FREE] - Mph, km/h or in physics m/s. How quickly an object is moving

​

• Velocity - The speed in a given direction

​

• Acceleration - How quickly an objects velocity is changing
