I really enjoyed the lesson Jack! I liked that video with the balancing pencil, definitely trying that! This is Ruth here, I will be the moderator for this session.
So Aaryan, in class we talked about different forces like those that push planes into the air, or knock buildings over, and we know that they’re simply known as ‘Forces’ (Gravity is possibly the most famous one!).
Any force is made by some sort of mass (or weight for simplicity’s sake), and something pushing that mass!
Think about me dropping the chalk in class, or the metal filings in the bucket with the magnet, they all have mass or weight, and they’re all being accelerated, or “pushed”, which causes a force!
So let’s say that chalk again! Let’s say the chalk weights 0.05kg, and we’re on earth, and we know that gravity on earth is 10 (this isn’t the exact figure, but that doesn’t matter to us right now!), then to get the force acting on the chalk that makes it fall, it would be 0.05 x 10, which is 0.5 Newtons! (Remember that Newtons are what we call the strength of the force).
So finally, let’s do an example from the worksheet:
How much force is on a 100 kg motorbike due to gravity?
This is easy so I’m sure you’ll get it really quickly! We know that the force is the mass(weight) multiplied by the number for gravity! So in our case its 100 x 10 = 1000 Newtons!
Let me know if this is still confusing!
Here’s a video that explains it but it might be a little too advanced, but I’m sure with some parental explaining, it would prove handy: https://www.youtube.com/watch?v=xzA6IBWUEDE

Thank you for putting the session together
Thanks very much Ruth!
Aaryan did not understand the second presentation and activity …relationship between force, acceleration and weight
Hi there,
I’ll run through this in a second reply, please allow me time to write something up for Aaryan.
Thanks!
Jack
Aaryan did not understand the second presentation and activity …relationship between force, acceleration and weight
is there a video that explains these terms and relationship
Hi again, thanks for waiting!

Thanks Jack…great video …Aaryan understands it now…:-)
Hi again, that’s great to hear! Glad I could help.

I really liked the way you explained in such a easy way.
I also come across one blog like this, I would like to share
https://erusuconsultants.com/innovations-in-structural-engineering/
this one is quite refreshing too
