Newton's Second Law

[@pickleshayley]

The teaching is so good

[@GuerrasLaws]

Without applying Energy from within you, one couldn’t push or pull on an object(s) regardless of how much Force you apply. Note: Force does not physically exist like an object with mass. Force is just an expression like one would use the word, “Love” to express one’s feelings.

[@PhysicsclassroomVideos]

It is true that the exertion of a force upon another object is often accompanied by energy changes within us. But a force is a push or pull that is exerted upon another object as a result of interacting /touching it. If you've ever been shoved, hit, bumped into, pulled, collided with, you've experienced a force. And I'm sure that you would deny its existence. And if you are currently sitting upon another object, you're then you are exerting a force upon it and it upon you (with little to no energy exertion). You can learn about the Newtonian definition of force in our video What is a Force?

tbh tis the best website to learn physics

That's so good to hear. Thanks.

This helped so much thru my grade 10 and 11 year . Thank you

[@stacy9841]

thank u!! so glad i found this account

On 9:29 how did you determine the F net?

[@NM-zb6pd]

Acceleration is directly proportional to net Force - How can this result be achieved or established independently by measuring F & a before even F=ma & 1 Newton is defined? If we observe that X increases with increase of Y then they could also be in a relation Y = (K * X cube). It need not be Y = K * X. We have to measure Y & X independently to establish Y is directly proportional to X i.e Y = K * X.
