As one of the first topics in A-level physics, kinematics introduces JC students to the variation of velocity and displacement with acceleration. Very often, they struggle with the graphical representations of the 3 variables. This Geogebra app allows students to vary acceleration (keeping it to a linear function for simplicity) while observing changes to velocity
The following simulation allows users to observe the effect of air resistance on a parachutist before and after he opens his parachute. Try to open the parachute when the man first reaches terminal velocity and observe the changes in velocity.
This is a simulation done from scratch after attending a crash course on EJSS. It displays the velocity and acceleration vectors as an object is projected vertically upward with a uniform downward acceleration. The initial upward velocity can be altered using a slider. The graph of velocity is traced as the ball moves. http://physicslens.com/ejss/verticalthrow_Simulation.xhtml
The following is a question (of a more challenging nature) posed to JC1 students when they are studying the topic of kinematics. A gun is aimed in such a way that the initial direction of the velocity of its bullet lies along a straight line that points toward a coconut on a tree. When the gun
I've used the open-source Tracker software, a video analysis and modeling tool built for use in Physics education, for both my IP3 and JC1 classes this year. Thanks to Mr Wee Loo Kang and his team for enthusiastically introducing this software to the physics teachers of Singapore. For the IP3 cohort, students were tasked to analyse the movement
A video tutorial on the use of the Addestation datalogger with its motion sensor to measure the displacement of a bouncing ball and to observe the velocity and acceleration using its differentiation function.
