The phenomenon of "learning loss" during the long summer holidays is well known so to keep your physics cogs turning, here's a brief challenge. I took my camera to the Five Mile Road on Saturday and photographed cars going past. The camera was set to 5fps so every sixth picture should have been recorded exactly … Continue reading Keep the cogs turning!
Home Study Projects
Constantly going over things that you have already learned can get a bit boring so if you want to extend your knowledge over the summer holiday then it's a good idea to do so using some fresh material. Finding suitable resources can be tricky so let me suggest some materials that are provided online at … Continue reading Home Study Projects
Acceleration
Acceleration is the rate of change of velocity. It is calculated by finding the change in velocity and dividing that number by the time taken for the change to occur, as shown in the word equation below; acceleration = (final velocity - initial velocity) / time taken This can be written in symbols using either … Continue reading Acceleration
Stopping Distance
The exam board appears to be very keen on aspects of physics that relate to real life - and vehicle stopping distance is an excellent example. You should therefore ensure that you are confident about this topic as there are standard "right" answers that you need to know. Stopping distances are divided into two parts. … Continue reading Stopping Distance
Newton’s Third Law
Newton's Third Law is all about situations where two objects are interacting with each other. A common way of stating Newton's Third Law is to say that for every action there is an equal and opposite reaction. This means different things in different situations. If the two objects are stationary, such as a person sitting … Continue reading Newton’s Third Law
Newton’s Second Law
We already know, from Newton's First Law, that everything has a natural tendency to maintain the same motion when all the forces acting on an object are balanced. But what happens when the forces are not balanced? That is where Newton's Second Law comes in. Newton's Second Law tells us that an object will accelerate … Continue reading Newton’s Second Law
Newton’s First Law
One of the most common misconceptions in GCSE Physics is that a force is needed to keep an object moving. In fact, a force is only needed to produce a change an object’s movement. This fact is Newton’s First Law of Motion, which is sometimes known as the Law of Inertia. Inertia is the tendency … Continue reading Newton’s First Law
Velocity-time graphs
We have extended our knowledge of graphs of motion by looking at velocity-time graphs. If you require more information then please read p23 in your CGP Complete Revision and Practice book (GCSE Edexcel Phyics). It is now time for you to test your knowledge and understanding. This is a compulsory homework task that you must … Continue reading Velocity-time graphs
Distance-Time graphs
We have covered the theory of distance-time graphs in class. If you require more information then please read p22 in your CGP Complete Revision and Practice book. It is now time for you to test your knowledge and understanding. This is a compulsory homework task that you must complete before your next Physics lesson. The … Continue reading Distance-Time graphs
