Grade 12 IEB definitions Physics 2023 Update Freefall - ANS-when the only force acting on an object is gravity conventional current - ANS-Current that flows from the positive side of the battery to the negative side motor effect - ANS-The motor effect is where a current carrying wire (or any other conductors) is put between magnetic poles, the magnetic field around the wire interacts with magnetic field it has been placed in. This causes the magnet and the conductor to exert forces o...

Chapter 5: Newton's Laws of Motion 1. Newton's First Law: An object will remain at rest or move in a straight line at constant speed unless acted upon by a net external force (law of inertia). 2. Newton's Second Law: The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = ma). 3. Newton's Third Law: For every action, there is an equal and opposite reaction. 4. Applications: Problems involving friction, tension, an...
