[S3 Physics PMCians]
What we did in 2 hours:
Last lesson, we started on Dynamics where we introduced Newton’s Laws (Yes, the famous one who had an apple dropped on his head, though it could just be a myth!)
Anyway, we learnt that Newton’s 1st Law explained how a body would behave if there’s no resultant force acting on it, and Newton’s 2nd Law shows how much a body would accelerate if there is a resultant force, giving us the very important equation: Resultant F = ma.
We learnt how to apply vector diagrams to solve for Forces as well.
By now, you would also have found out that Kinematics is very commonly integrated with Dynamics whereby many questions require understanding of both concepts to solve.
What you take home:
Below is an excellent simulator on Forces and Acceleration, do try out the different simulations to see how resultant force affects the motion on an object. Enjoy and have fun with it!
