Welcome to the GCSE Physics Ninja **Mass & Forces **course.

These video lessons are based on question-and-answer flashcards. You can either make your own or purchase the printable flashcards from the shop.

All flashcards are relevant to GCSE, IGCSE (CIE and EdExcel), and IB unless indicated.

## What will I learn in this course?

When you have completed this course, you will be able to...

- Understand the difference between
**mass and weight**. - Explain the effects of
**forces**. - Calculate the
**resultant force**on an object. - Use
**Newton's laws**to analyse the motion of an object subjected to forces. - Explain the effect of
**friction forces**on falling bodies. - Understand the factors affecting
**stopping distance**. - Interpret
**force - extension graphs**for different materials - Calculate
**extension**of a spring using**Hooke's Law**. - Explain the difference between
**elastic and plastic deformation**. - Understand the term
**centre of mass**and use it to determine the**stability**of objects. - Explain and calculate the
**moment**due to a force. - Become familiar with the idea of
**momentum**and its conservation. - Be able to use
**impulse**to calculate forces and time of impact. - Explain how a force can cause
**pressure**and perform calculations. - Calculate
**pressure vs. depth**in liquids. - Use the idea of
**particles**to describe how a gas exerts a**pressure**on the walls of a container. - Understand how machines that use pressure can be
**force multipliers**.
