AC HPAT PHYSICS 2024 QUESTIONS WITH COMPLETE SOLUTIONS GRADED A+ DIstance - CORRECT ANSWER · Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement - CORRECT 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 - CORRECT ANSWER · Position is a place 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 - CORRECT ANSWER · Speed is the 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 - CORRECT ANSWER · Acceleration is the rate of change of velocity with time. Instantenous velocity - CORRECT 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 o bject has a standard velocity over a period of time, its average and instantaneous velocities may be the same. A force - CORRECT 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 AC HPAT PHYSICS 2024 QUESTIONS WITH COMPLETE SOLUTIONS GRADED A+ 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 - CORRECT 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 - CORRECT 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 alon g the straight line with variable speed. In uniform motion, body covers equal distance in equal interval of time What is the difference between constant, instantaneous, and average speed? - CORRECT ANSWER · constant speed is where the speed is the same throughout and instantaneous speed is speed given at any moment and average speed is a total distance traveled divided by the amount of time it took to travel it. Newtons Laws - CORRECT ANSWER Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change 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.
