IB-Physics-Core-Notes Topic 2 Mechanics 2.1 Kinematics 2.1.1 Define displacement, velocity, speed and acceleration. Displacement- Defined as the change in position of an object. Displacement is a quantity that has both direction and magnitude, it is a vector. Measured in metres. Speed- How far an object travels in a given time. Rate of change of distance (ms-1) Velocity- The vector version of speed. Tells us the magnitude of how fast an object is moving and the direction in wh...

1.1 Introduction There is no chemical reaction in which energy is not involved.In the process of reacting substances, you either supply energy to the system or the reaction occurs on its own. But then, why and how do chemical reactions occur? What exactly is thermodynamics? Why do some chemical reactions occur without the supply of external energy? All these questions will be answered in this module. You will also be introduced to some of the terms used in thermodynamics. 1.2 Objectives ...
