Projectile Motion
The steel ball will be launched horizontally by being released at a certain height on the ramp. It will then fall to the floor and make a mark on the landing paper. The horizontal distance from take-off to landing, x, is proportional to the initial horizontal velocity, v0, of the ball. The distance, x, can be measured with the meter stick. By using the SALT®, photogate and computer, the time ca...
متن کاملProjectile Motion
Introduction: A projectile is a body in free fall that is subject only to the forces of gravity (9.81ms⎯2) and air resistance. An object must be dropped from a height, thrown vertically upwards or thrown at an angle to be considered a projectile. The path followed by a projectile is known as a trajectory. If gravity were not present, a projectile would travel in a constant straight line. Howeve...
متن کاملStudents’ Prior Knowledge of Data Visualization
Undergraduate students who enroll in a data science course already have exposure to visualization in different contexts, and hold beliefs about acceptable standards of visualization. When confronted with non-traditional examples of visualization, such as the ones found in the popular blog Dear Data http://www.dear-data.com/, their reactions are mixed. Some are surprised by the creativity of the...
متن کاملPrior Knowledge Based Motion Model Representation
This paper presents a new approach for human walking modeling from monocular image sequences. A kinematics model and a walking motion model are introduced in order to exploit prior knowledge. The proposed technique consists of two steps. Initially, an efficient feature point selection and tracking approach is used to compute feature points’ trajectories. Peaks and valleys of these trajectories ...
متن کاملProjectile Motion in Real Life
Projectile motion is a fundamental concept in basic physics courses. The often used simplified calculations, where air resistance is neglected, are obviously not relevant for many real life events. Using a video camera and computer software, students can investigate the influence of air resistance on for instance the trajectory of a football. The video sequences are digitised and the xand y-pos...
