## Hydraulic Press Simulation

This simulation can be used for O-level Physics, for the topic of Pressure. I created it as it was relevant to our school’s IP3 physics as well. It demonstrates the working principle of a hydraulic press. By adjusting the cross-section… Continue Reading

## Tensegrity Explained

There is a new internet trend called “tensegrity” – an amalgamation of the words tension and integrity. It is basically a trend of videos showing how objects appear to float above a structure while experiencing tensions that appear to pull… Continue Reading

## Forces in Equilibrium

While preparing for a bridging class for those JAE JC1s who did not do pure physics in O-levels, I prepared an app on using a vector triangle to “solve problems for a static point mass under the action of 3… Continue Reading

## Newton’s 2nd Law Questions

Here are the steps to solving a problem involving Newton’s 2nd law. Step 1: Draw a free body diagram – where possible, sketch a free body diagram to represent: the body isolated from other objects the forces acting on the… Continue Reading

## Free-Body Diagrams in Two-Body Motion

Students are often confused about the forces in drawing free-body diagrams, especially so when they have to consider the different parts of multiple bodies in motion. Two-Body Motion Let’s consider the case of a two-body problem, where, a force F is applied… Continue Reading

## Newton’s 3rd Law

Activity 1: Propeller Cart (Predict, Observe and Explain) Activity 2: Untied Balloon A balloon is filled with air and released with its mouth downwards. Explain why it moves upwards.                       why it stops rising after some time.    Activity 3:… Continue Reading

## Relationship between displacement-time and velocity-time graphs

Through this GeoGebra app, students can observe how the gradient of the displacement-time graph gives the instantaneous velocity and how the area under the velocity-time graph gives the change in displacement. In the GeoGebra app below, you will see a… Continue Reading

## Instantaneous vs Average Velocity

This GeoGebra app allows students to observe the difference between instantaneous and average velocity from a graphical perspective.

## Work Done Simulation

This GeoGebra app allows users to change the magnitude and direction of the force acting on an object, as well as the initial velocity. The change in kinetic energy is calculated along with the work done in the direction of… Continue Reading
