experiments: To demonstrate the conservation of momentum
Mandatory experiments: To show that a ∝ F Verification of the principle of conservation of momentum Measurement of g
Formulae: Force: F = ma Momentum: p = mv
Conservation of momentum: m1u1 + m2u2 = m1v1 + m2v2
Universal gravitation: F = Gm1m2
_________ d2
47 BOOK TITLE Derivations: F = ma
Laws: Newton’s three laws of motion Law of conservation of momentum Newton’s law of universal gravitation
STS: Advantages/disadvantages of friction Conservation of momentum in guns/ bullets (recoil) and vehicle impacts Application of Newton’s three laws (for example, objects at rest or constant velocity; rockets taking off; seat-belts restraining motion
Terminal velocity and weightlessness Gravitational effect on solar system and atmospheric presence
