Excellent work Bright Side, Newton would be very proud of you! Can I ask a couple of questions please? 1. What happens when we apply that “net” force at right angles to the straight line motion? And, 2. You explained “net” Force and Acceleration perfectly, and _F=mA_ correct! but, what exactly is “mass” ? And, can we be sure it remains constant at high velocities…Hmm, maybe, we’ll both have to wait for Mr Einstein to arrive? Take care and I look forward to your next video. Thank you.
When a body in straight line motion is acted upon by a net force at right angles to its direction of motion, it will experience an acceleration perpendicular to its initial direction of motion. This is known as centripetal acceleration. Centripetal acceleration is proportional to the square of the speed of the object and inversely proportional to the radius of curvature of its path. The force required to produce this acceleration is known as the centripetal force and is given by the equation F = mv^2/r, where m is the mass of the object, v is its speed, and r is the radius of curvature of the path. In order for a body to continue moving in a circular path, it must experience a constant centripetal force directed towards the center of the circle. If this force is removed, the body will continue moving in a straight line along its tangent to the circle.
@@brightsidescience Hi Bright Side, thank you for conversing with me, you’re right! So, we could say that the centripetal force is preventing the object from continuing with a straight line motion. The centripetal force is not causing it to continue moving on a curved path, that is all down to its inertia. And we have to introduce an ‘apparent’ force with a value equal to minus mv^2/r to keep the “net” forces at the centre of the object at zero. Otherwise, the object would accelerate and move in the direction of the unbalanced force. The ‘apparent’ force we introduce is called the centrifugal force. And, that is why your tides video is absolutely correct. Well done. You know, I’d really appreciate your opinion on my little video, because I was attempting to explain what happens to tides, when we neglect to consider the centrifugal effect. Thanks
@@brightsidescience As for your bright side videos being aimed at young kids, then all I can say is that you keep them clear and simple enough for all ages to understand, and that’s the real key to excellent teaching. Thank you.

If Newton is proud of this, then it is a big thing right? And this video is meant for small kids.

As first law you pls also describe history of 2 law
Would you like a brief history of the second law?
