Honors Physics Final Exam Questions and Answers Graded A+ What is the principle of inertia? The principle of inertia states that an object will not change its state of motion unless acted upon by an external force. How does friction affect the motion of an object? Friction opposes the motion of an object, causing it to slow down or stop. What is the concept of momentum? Momentum is the quantity of motion an object has, which depends on its mass and velocity. What is the dif...

1. An induction clutch works by: magnetism 2. If a first class lever with a resistance arm measuring 2 feet and an effort arm measuring 8 feet are being used, what's the mechanical advantage?: Length of Effort Arm ÷ Length of Resistance Arm. MA = 8 ÷ 2 = 4 3. The force produced when a boxer's hand hits a heavy bag and "bounces" off it is called: recoil 4. If Gear 1 has 25 teeth and Gear 2 has 15 teeth, how many revolutions does Gear 2 make for every 10 revolutions Gear 1 makes?: r = DR/...
