The Key Stage 1, 2 and 3 along with GCSE section covers a range of subjects. In Key Stage 1, 17 subjects are available, including Art and Design, Computing, Design and Technology, English, Geography, History, Maths, Music, Physical Education, PSHE, Citizenship, Religious Education, Science, and Modern Foreign Languages.

From April 2020, teachers from English state schools created and uploaded video lessons each week. Every lesson is an hour long and includes a quiz, a video explanation from the teacher, and a worksheet. [19] From April 2020, the TES and Oak National Academy ran weekly assemblies. [20]
In the first case the force is continuously applied to the car by a person, while in the second case the force is delivered in a short impulse. Contact forces are often decomposed into orthogonal components, one perpendicular to the surface(s) in contact called the normal force, and one parallel to the surface(s) in contact, called the friction ...
The SI unit of force is the newton (symbol N), which is the force required to accelerate a one kilogram mass at a rate of one meter per second squared, or kg·m·s −2.The corresponding CGS unit is the dyne, the force required to accelerate a one gram mass by one centimeter per second squared, or g·cm·s −2. A newton is thus equal to ...
The National Curriculum for England is the statutory standard of school subjects, lesson content, and attainment levels for primary and secondary schools in England. It is compulsory for local authority-maintained schools, but also often followed by independent schools and state-funded academies.
The most familiar non-contact force is gravity, which confers weight. [1] In contrast, a contact force is a force which acts on an object coming physically in contact with it. [1] All four known fundamental interactions are non-contact forces: [2] Gravity, the force of attraction that exists among all bodies that have mass. The force exerted on ...
The friction drag force, which is a tangential force on the aircraft surface, depends substantially on boundary layer configuration and viscosity. The net friction drag, , is calculated as the downstream projection of the viscous forces evaluated over the body's surface. The sum of friction drag and pressure (form) drag is called viscous drag.
A lever amplifies an input force to provide a greater output force, which is said to provide leverage, which is mechanical advantage gained in the system, equal to the ratio of the output force to the input force. As such, the lever is a mechanical advantage device, trading off force against movement.
