A body of mass m, projected at an angle of from the ground with an initial velocity of v, acceleration due to gravity is g, what is the maximum horizontal range covered a) R v 2 (sin 2)/g. Furthermore, this experimental setup will not be appropriate to determine the value for gravity, affecting validity.Īccess our library of Physics Practical Investigations. This set of Physics Multiple Choice Questions & Answers (MCQs) focuses on Simple Projectile Motion.
Hence the range of a projectile can be expressed in terms of the horizontal velocity and the other control variables such as y and g by substituting t=\sqrt this will indicate a larger value of g than the true value. To express the time of flight t in terms of the acceleration due to gravity, we analyse the vertical motion of the projectile Hence this experiment is based on the equation s_x=u_xt. In this situation, the range of a projectile is dependent on the time of flight and the horizontal velocity. The simplest type of projectile motion is a ball being projected horizontally from an elevated position. Let’s apply the scientific method to design and conduct a practical investigation for the assessment task outlined above. In this sample practical assessment task, we are required to investigate the relationship between the range s_x and the launch velocity of a projectile released from an elevated position.
Design and conduct a practical investigation to collect primary data to validate the relationship between the launch velocity and the range of a projectile.Task weightingĢ0% of Overall school assessment Description of Assessment Task Task 1 of 4 Open-Ended Investigation Report on Projectile Motion from Module 5 Advanced Mechanics. This is because most Projectile Motion practical investigation is relatively easy to design and conduct by students.Ī typical Projectile Motion practical assessment task used by schools is outlined below. Projectile motion experiment is used by most schools for their first Physics practical assessment task. It is clear, from the above equation, that air drag causes the projectiles horizontal velocity, which would otherwise be constant, to decay exponentially. A trajectory is a path taken by a projectile.Sample Physics Practical Assessment Task: Projectile Motion Experiment This is not to say that other forces do not act on it rather, their impact is minimal when compared to gravity. The primary force acting on a projectile is gravity. Projectile MotionĪ projectile is any object thrown into space with only gravity acting on it. (Please keep in mind that this definition assumes that the upwards direction is defined as the positive direction, if the coordinate system is arranged in such a way that the downward direction is positive, the acceleration due to gravity is positive.)īecause the accelerations are constant, the kinematic equations can be applied.

On the other hand, vertical velocity varies linearly. At any point in the projectile motion, the horizontal velocity remains constant.
