Forces and moments structured questions
Written practice in force balance, momentum, impulse and moments. Five questions are selected for each attempt.
Learning goals
- Describe the forces on a mass, a charge and a current-carrying conductor in gravitational, electric and magnetic fields.
- Describe normal, frictional, buoyant and viscous forces qualitatively.
- Apply Hooke's law within the limit of proportionality.
- Apply moments, couples and force-and-torque equilibrium using free-body diagrams and vector triangles.
- Treat the weight of a body as acting at a single point, its centre of gravity
- Apply the principle of moments to new situations and problems
- Explain inertia and momentum, then apply Newton's laws using free-body diagrams.
