The work energy theorem - Study guides, Class notes & Summaries

How can you calculate the mechanical advantage a simple machine provides? divide the output force by the input force How can a simple fixed pulley make a job easier? by changing the direction at which the force needs to be applied A pulley system has a mechanical advantage of 3, and an object weighing 9 Newtons must be lifted 15 meters. How much force must be applied to lift the object? Use the following equation to find the answer:MA=Fo/Fi 3 N How is the work energy the...

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...

Units of G = N∗m²/kg² Correct Answer Force of Gravity Between Two Objects Correct Answer Kinetic Friction Correct Answer Static Friction Velocity vector is constantly changing and is tangential to the circle of motion Correct Answer Uniform Circular Motion - Velocity The acceleration vector always points toward the center of the circle and constantly changes direction as the object moves. Correct Answer Centripetal Acceleration Correct Answer Centripetal Force θ = angle...

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...
