dynamics. Kinematics describes motion without regard to its causes. In this experiment‚ kinematics focuses in one dimension: a motion along a straight line. This kind of motion‚ actually any kind of motion‚ involves velocity‚ displacement‚ and acceleration with regards to time. The objectives of the experiment are to draw the displacement versus time graphs and velocity versus time graphs for uniform motion and uniformly accelerated motion‚ and to determine one’s normal reaction time and his reaction

(A) A (B) B (C) both A and B (D) neither A nor B (E) It is not possible to determine Answer: D On a Velocity vs Time graph‚ constant non-zero acceleration means that we should be seeing a diagonal line. Neither graph qualifies. 4. Which particle is in its initial position at t = 2 seconds? (A) A (B) B (C) both A and

makes it hard to make any predictions on the basis of previous experience. The author outlines several functions as to why project management must be relevant in order to keep up with the societal change. First was a knowledge based society. The acceleration of technology will inevitably force everything and everyone to change and evolve as it does. As the author quotes “change has thus transformed and continues to transform‚ the world which we live.” Another key point pertained to the responses to

Calculate its velocity after 2.5s if it is dropped: a. On Earth‚ where the acceleration due to gravity is 9.8m/s2. b. On Mars‚ where the acceleration due to gravity is 3.8m/s2. 3. A motorbike is travelling with a velocity of 3m/s. It accelerates at a rate of 9.3m/s for 1.8s. Calculate the distance it travels in this time. 4. A Tesla Roadster car accelerates from

Every day we deal with forces of one kind or another. A pressure is a force. The earth exerts a force of attraction for all bodies or objects on its surface. To study the forces

were designed to be towed to the target area by a full-sized “mother” submarine. The X-craft would then be detached and infiltrate the target‚ laying down two side charges‚ each containing 2 tonnes of amatol. They would then make their escape and rendezvous with the “mother” submarine to be towed home. The first attack was launched against the German battleship Bismarck. Six X-craft were designated for the operation‚ but two were lost to accidents en route‚ and a third suffered mechanical problems

The purpose of this graph is to describe the acceleration of a free-falling object as being either constant or changing; as being directed upward‚ downward or both (depending on some other variable); and as having a particular numerical value.This lab deals with the motion of an object falling freely (assuming negligible air friction) under the force of gravity. The position of a falling object will be measured as a function of time‚ and its acceleration will be determined from those data. In regard
