Forces and moments written questions
Practise H1 Physics forces, moments, couples and equilibrium through written questions with worked solutions.
Learning goals
- Describe the forces on a mass, a charge and a current-carrying conductor in gravitational, electric and magnetic fields.
- Describe normal, frictional and viscous forces, such as air resistance, 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.
