On successful completion of this module students should be able to:
1. Recall Newton's laws of motion in qualitative terms.
2. Apply ideas about Newtonian Mechanics to calculate solutions to simple problems on forces.
3. Apply the principles of conservation of energy and momentum to solve simple problems.
4. Apply the kinetic theory of gases to a range of simple problems.
5. State and interpret Kepler's laws of planetary motion.
This module explores the success of Newtonian physics in explaining the world around us - from the behaviour of gases to the orbit of planets. Starting from the cornerstone of Newton's three laws, the module progresses to examine the interaction of forces and material objects and introduces the concept of a central force field. Topics covered include: conservation laws, rotational motion, gravitational fields and potential, projectiles and intermolecular forces, kinetic theory of gases, and a qualitative description of the nature of the 4 fundamental forces.
Definitions of force, vector and scalar quantities addition of vectors.
Components of vectors, adding vectors by components.
Forces in equilibrium.
Newton's three laws of motion.
Impulse; conservation of momentum, elastic and inelastic collisions.
