AC HPAT Physics Exam Questions And Answers (Updated And Verified) DIstance - answer✔✔· Distance is a scalar quantity that refers t o "how much ground an object has covered" during its motion. Displacement - answer✔✔· Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position. Position - answer✔✔· Position is a pl ace where someone or something is located or has been put. In physics, position is usually a number on an axis. ... Position is a vector, because direction matters. But distance is a scalar. Distance is how far you've traveled. Speed - answer✔✔· Speed is t he distance traveled per unit of time. It is how fast an object is moving. Speed is the scalar quantity that is the magnitude of the velocity vector. It doesn't have a direction. Acceleration - answer✔✔· Acceleration is the rate of change of velocity with time. Instantenous velocity - answer✔✔· Instantaneous velocity is the velocity of an object in motion at a specific point in time. This is determined similarly to average velocity, but we narrow the period of time so that it approaches zero. If an object h as a standard velocity over a period of time, its average and instantaneous velocities may be the same. A force - answer✔✔a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate. Force can also be described intuitively as a push or a pull Net force - answer✔✔· Net force is the vector sum of forces acting on a particle or body. The net force is a single force that replaces the effect of the original forces on the particle's motion. It gives the particle the same acceleration as all those actual forces together as described by the Newton's second law of motion. Uniform vs. non -uniform motion - answer✔✔· Difference between uniform and non -uniform motion with examples. In Uniform motion, movement of a body is along the straight line with constant speed. In non uniform motion, movement of a body is along the straight line with variable speed. In unifo rm motion, body covers equal distance in equal interval of time What is the difference between constant, instantaneous, and average speed? - answer✔✔· constant speed is where the speed is the same throughout and instantaneous speed is speed given at any mo ment and average speed is a total distance traveled divided by the amount of time it took to travel it. Newtons Laws - answer✔✔Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to chang e its state by the action of an external force. The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The third law states that for every action (force) i n nature there is an equal and opposite reaction. Coefficient of friction - answer✔✔· A coefficient of friction is a value that shows the relationship between two objects and the normal reaction between the objects that are involved. ... The coefficient of friction depends on the objects that are causing friction. The value is usually between 0 and 1 but can be greater than 1. Torque - answer✔✔Torque is a measure of the force that can cause an object to rotate about an axis. Just as force is what causes an object to accelerate in linear kinematics, torque is what causes an object to acquire angular acceleration. Torque is a vector quantity Mechanical advantage - answer✔✔· Mechanical advantage is the ratio of the force produced by a machine to the force applied to it, used in assessing the performance of a machine. Input vs output force - answer✔✔· The difference between the two is very simpl e to understand: Input Force represents the amount of force that you put into another object. Output Force represents the force that a specific object has as a result of the input force. Gravitational force - answer✔✔· The gravitational force is a force th at attracts any two objects with mass. ... In fact, every object, including you, is pulling on every other object in the entire universe! This is called Newton's Universal Law of Gravitation. Friction - answer✔✔· Friction is a force that holds back the mov ement of a sliding object. That's it. Friction is just that simple. You will find friction everywhere that objects come into contact with each other. Normal force - answer✔✔· The normal force is the support force exerted upon an object that is in contact w ith another stable object. For example, if a book is resting upon a surface, then the surface is exerting an upward force upon the book in order to support the weight of the book. Tension - answer✔✔· tension is described as the pulling force transmitted ax ially by the means of a string, a cable, chain, or similar one -dimensional continuous object, or by each end of a rod, truss member, or similar three -dimensional object kinetic friction - answer✔✔· Kinetic friction magnitude is directly proportional to the normal force magnitude and the roughness between the sliding surfaces. Static friction magnitude is
