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...

Honors Physics Midterm Questions with Certified Answers What is the difference between speed and velocity? Speed is the measure of how fast an object is moving, while velocity includes both the speed and the direction of the object's motion. How does Newton's Third Law of Motion apply to interactions between two objects? Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction, meaning that when one object exerts a force on a second obj...
