Episode 8 – Sciences (Theory) Part 1: Physics

I encountered Physics in Formula 1, Helicopters, Aviation, and Robotics. So I can provide context to the child to stimulate interests. One of my favourite professional experiences was the conditioning flight test data for a training simulator. So pilots can handle any manoeuvres on their first time in the helicopter because the “L” sign are not used on a helicopter. From the data, you can see how pilot movement on the cyclic control is translated into the motion response of the helicopter. The trainee learns to fly through the combination of the screen, the simulator’s motion, and the actuators’ forces on the seats. Please leave a comment on what your favourite physics related topics are, and we can discuss the underlying physics further.

The Physics theory topics for 2021 and 2020 are:-

KS2021 (Theory Q4) – Newtons 2nd Law. Resultant Force = Mass x Acceleration. Mechanics questions are fundamental theories. Free body force diagrams are useful to visual aid of what is happening. What is Newton’s 1st Law?

What is rate of change? What is the rate of change of speed? What is the rate of change of distance? What is the difference between distance and displacement? Scalars and vectors. Understanding of integration and differentiation to move from Acceleration to velocity to displacement would be useful.

The astrophysics question (KS2021 Q5) is classified in Physics too. Logic and background reading about space would help to answer these questions.

KS2020 (Theory Q1) – One has to memorise the Centripetal force = mass x velocity2 / radius equation. Understand the relationship between speed, distance and time. [hint] Look at the SI Units.

Constant change in displacement equals to constant acceleration. (think change in gradient/slope). Constant change in speed equals to constant acceleration or deceleration.

Energy, thermodynamics, basically energy convert from one form into another. In this case, the gravitation potential energy is ultimately converted into heat. Port-Hamiltonian theory would help in this case. The total energy of in a closed system can only be stored, or dissipated. So if it is not stored, it is dissipated.
