[accordions autoHeight='true'] [accordion title="1. Rotational Kinematics"] Angular displacement is defined as the angle an object turns with respect to the centre of a circle. where s is the arc and r is the radius of the circle. One radian is the angular displacement when the arc length is equal to the radius of the circle.
[accordions autoHeight='true'] [accordion title="1. Work Done"] Work done W is defined as the product of the force and the displacement made in the direction of the force. For a constant force F acting in same direction as the displacement s: W = F . s If is the angle between F and s: Work
This is a game that I play with my classes in the beginning of the course after they have attended the first lecture on base units. It serves as an ice-breaker since this is usually when I first meet them, as well as a recap of what they have learnt. The rules are stated in
For my students to discuss. Please leave your answer and explanation in the comments below. Options are: A. (peak voltage) B. C. Zero D. None of the above
This is an easy-to-use interactive simulation for P-V diagrams, created in GeoGebraTube (not by me!). Students will get to test themselves and familiarise themselves with making quick calculations for simple processes.
This picture has been making its way around the internet. This is a Primary 6 Science question that has a questionable answer. As teachers, there are times when we make mistakes in crafting answers for a multiple-choice question. Good thing there is often a fail-safe in the form of our colleagues who would help each
A concept cartoon is an innovative way of eliciting discussions about science concepts. For example, it can present differing views on a scientific phenomenon from different characters. I am not an artist but do wish sometimes that I could make classroom discussions more interesting by using relevant cartoons or comic strips. Then I stumbled upon
This is an interesting question on electricity: in order to survive a lightning strike, which of the following costumes offer the best protection? A coat of armour, your birthday suit, a wetsuit or a superman costume? Watch this MinuteEarth video on Faraday's cage to find out!
