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.

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.
