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
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
Scalars and Vectors
You must know the definitions of a scalar and a vector. A scalar is a quantity that has magnitude only (it has no direction). Common examples include; temperature, speed, mass and distance. A vector is a quantity that has both magnitude and direction. Common examples include; forces, velocity, acceleration and electric current. There are a … Continue reading Scalars and Vectors
