CIE IGCSE Physics Equations For Guaranteed Success 1. Define speed. - Speed is the distance traveled per unit of time. 2. Define acceleration. - Acceleration is the change in velocity per unit of time. 3. Define velocity. - Velocity is the displacement per unit of time. 4. Define weight. - Weight is the gravitational force acting on an object, calculated as mass multiplied by gravitational acceleration. 5. Explain Hooke's Law in terms of force. - According to Hooke's Law, the force...

Edexcel IGCSE Physics Unit 8 – Astrophysics Complete Guide 1. Universe - Defined as an immense collection of billions of galaxies. 2. Galaxy - Refers to a large grouping of stars, often along with gas and dust, held together by gravitational forces. 3. Milky Way - Specifically, it's the galaxy that contains our solar system, including Earth and the Sun. 4.

Forces - Physics - IGCSE – CIE Graded A+ 1. Force - Force is a push or pull applied to an object. 2. Forces - Forces can change the shape, size, speed, and direction of an object. 3. Newton - The Newton is the SI unit of force. 4. Newton's First Law - Newton's first law states that an object at rest will remain at rest, and an object in motion will remain in motion unless acted upon by an unbalanced force. 5. Newton's Second Law - Newton's second law describes how the accelerat...

Edexcel IGCSE Physics – Equations Verified Guide 1. What does average speed represent? - Average speed is calculated as the distance traveled divided by the time taken. 2. Define force in terms of its components. - Force is the product of mass and acceleration, according to Newton's second law. 3. Explain acceleration in relation to changes in velocity. - Acceleration is the rate at which velocity changes over time. 4. Define momentum and its components. - Momentum is the product of m...

A complete list of past paper questions (3 marks, 4 marks, 5 marks and 7 marks) compiled from the last 10 years of CIE IGCSE Geography past papers, organised by category, specific to Unit 1 (population dynamics) of Theme 1 (population & settlement). Quizlet sets to revise this content are available for a small additional charge upon request. Because CIE only have a finite list of questions to choose from, I found revising content from past questions to be a key part of my revision process.
