OCR B Explaining Motion
This is a large and important area of your GCSE physics. It explains how the world that we can see around us works.
Choose your topic:
- Newton's Third Law - Pairs of forces acting on different objects
- Scalars and Vectors [FREE] - These quantities both have a size, but vectors also have a direction
- Forces [FREE] - Something that acts on an object due to its interaction with another object
- Distance [FREE] - How far something moves, and how this is related to displacement
- Speed [FREE] - Mph, km/h or in physics m/s. How quickly an object is moving
- Velocity - The speed in a given direction
- Acceleration - How quickly an objects velocity is changing
- Motion Graphs - Distance-time and velocity-time graphs
- v squared - u squared - A special equation used for uniform motion
- Resultant Force [FREE] - This is the overall force that acts on an object
- Free Body Diagrams - These allow us to clearly see all the forces acting on an object
- Momentum - An introduction to momentum for higher tier students
- More Momentum - More advanced calculations involving conservation of momentum
- Newton's First and Second Laws - The forces that act on one object
- Motion in a Circle - Constant speed but changing velocity
- Moments - The turning effect of a force
- Gears - These transmit the rotational effect of a force
- Stopping Distances - The factors affecting vehicles slowing down
- Work Done - Work is done when a force causes an object to move a distance
- Stores and Transfers [FREE] - Energy can be stored in many ways
- Stores and Transfers: Examples [FREE] - Descriptions of the changes involved transferred
- Kinetic Energy [FREE] - How to calculate the energy stored in moving objects
- Gravitational Potential Energy [FREE] - When an object moves up or down
