Newton's first law! Forces cancel each other out = no resultant force = no acceleration! To START lifting something, you need to put in more force though.
When lifting an object vertically upwards at a constant speed, meaning that you're lifting it at the same speed with no change. Therefore your normal contact reaction force is equal to the weight of the object being lifted upwards
Thank you so much these videos are extremely helpful :)
Please could you do the International edexcel A/As level chemistry as well!
wow what an amazing video! thank you so so much ❤
could you make these into pdfs
this was very helpful, appreciate the hard work going into these! can i know if you're planning to do units 3 and 6, and if so, when?
Good video❤😊
I don’t get how lifting at a constant speed means I’m lifting with a force equal to the weight. I’d appreciate it anyone could explain

@@ScienceShorts OHHHH THX A LOT
Also, could you explain why things topple over (for reference, look at October 2021 q19 a)
