Newton’s laws, connected particles and friction

By the end you’ll be able to

• state and apply Newton’s first, second and third laws of motion in particle models
• use $\mathbf{F}=m\mathbf{a}$ in component form for motion in a straight line or in two perpendicular directions, with consistent sign conventions
• model connected particles joined by a light inextensible string passing over a smooth pulley, and use common acceleration and uniform tension where the model implies them
