Newton's second law, F=ma, describes the relationship between an external force on an object F, the mass of the object m and the resulting acceleration of the object a. We can see that the acceleration of...

For this we must take a step back and analyse the meaning of acceleration. Acceleration is a change in VELOCITY - this is very important. Velocity is speed in a particular DIRECTION. You may be confusing ...

When approaching a Physics problem in IB, it is especially important to reread the question a couple of times and note down any information that you might think is relevant to solving the question and sta...

Because velocity is a vector and therefore has both magnitude and direction. Thus as the lorry is changing direction whilst travelling around the roundabout its velocity is also changing (velocity = displ...

That is a good question. F=ma is a special case of Newton's 2nd Law of Motion . Newton's second law states that: The rate of change of linear momentum is proportional to the applied force and acts in the ...
