Impulse and MomentumSign up

understand how to use the equation impulse = F t = p (Newton's second law of motion) · CORE PRACTICAL 9: Investigate the relationship between the force exerted on an object and its change of momentum · understand how to apply conservation of linear momentum to problems in two dimensions · CORE PRACTICAL 10: Use ICT to analyse collisions between small spheres, e.g. ball bearings on a table top · understand how to determine whether a collision is elastic or inelastic · be able to derive and use the equation Ek = p^2 / 2m for the kinetic energy of a non-relativistic particle

Circular MotionSign up

be able to express angular displacement in radians and in degrees, and convert between these units · understand what is meant by angular velocity and be able to use the equations v = omega r and T = 2 pi / omega · be able to use vector diagrams to derive the equations for centripetal acceleration a = v^2/r = r omega^2 and understand how to use these equations · understand that a resultant force (centripetal force) is required to produce and maintain circular motion · be able to use the equations for centripetal force F = ma = m v^2 / r = m r omega^2.
