# Linear motion under a variable force – Further Mechanics Paper 3

Candidates should be able to:

• solve problems which can be modelled as the linear motion of a particle under the action of a variable force, by setting up and solving an appropriate differential equation.
Including use of $$v\frac{dv}{dx}$$ for acceleration, where appropriate.
Calculus required is restricted to content from Pure Mathematics 3 in Cambridge International A Level Mathematics (9709).
Only differential equations in which the variables are separable are included.
