H1 Physics: Forces and Moments structured questions
Write answers for Forces and Moments, then use the marked parts and worked solutions to check your method.
Learning objectives
- Explain inertia and momentum, then apply Newton's laws using free-body diagrams.
- show a qualitative understanding of forces including normal force, frictional force and viscous force, e.g. air resistance (knowledge of the concepts of coefficients of friction and viscosity is not required)
- Apply Hooke's law within the limit of proportionality.
- Apply moments, couples and force-and-torque equilibrium using free-body diagrams and vector triangles.
- show an understanding that the weight of a body may be taken as acting at a single point known as its centre of gravity
- apply the principle of moments to new situations or to solve related problems
