# B.2. Thermodynamics

At GCSE we were happy with speed = distance/ time - an equation that is very useful when we talk about movement at a CONSTANT SPEED. If something is  accelerating, that equation is less useful.

Now, at IB we start thinking about movement with CONSTANT ACCELERATION. For this, we have a set of equations you probably know as the SUVAT equations.
