WebStudy with Quizlet and memorize flashcards containing terms like Suppose an object in free fall is dropped from a building. Its starting velocity is 0m/s. Ignoring the effects of air resistance, what is the speed (in m/s) of the object after falling 3 seconds?, Which of the following is the best definition of gravity?, A student has two identical sheets of paper. … WebThe average speed is the distance (a scalar quantity) per time ratio. Speed is ignorant of direction. On the other hand, velocity is a vector quantity; it is direction-aware. Velocity is the rate at which the position changes. The average velocity is the displacement or position change (a vector quantity) per time ratio.
WebA projectile is an object upon which the only force is gravity. Gravity acts to influence the vertical motion of the projectile, thus causing a vertical acceleration. The horizontal motion of the projectile is the result of the … WebApr 5, 2006 · Velocity is defined as a vector measurement of the rate and direction of motion. Put simply, velocity is the speed at which something …
