Newton's 2nd Law (1 of 21) Calculate Acceleration w/o Friction, Net Force Horizontal

Shows how to use Newton's Second Law of motion to calculate the acceleration of an object. The acceleration of an object is directly proportional to the net force applied to the object and inversely proportional to the mass of the object. The second law can also be stated in terms of an object's changing momentum, such that the rate of change of momentum of an object is directly proportional to the net force applied and the change in momentum is in the direction of the net force.

Just taking out some unwanted umms and uhhs. Thanks for watching!

F(g) was calculated using 11n instead of 9kg for the second 0rob

Thanks for taking the time to comment, I will recheck my math.

Thank you! You are the best lecturer!

i see u removed the first one :O make more video's related to grade 11 physics :) plz and thank you

you could just do 5/6 because 1 newton is the amount of force needed to move a kilogram a m/s

Tq very much.. it's really helpful

I’m confused about one thing. I got a fbd and it already has 2 downward forces and 1 upward force. Do I still need to find the gravity force or what? What I do with the 2 downward forces?

[paganimarker]

shouldn`t we put 9 instead 11? when we calcuate F_g in second equation

[KAROLsBlue]

Sir, why is it necessary to have negative applied force when it is going to the left?

Hi Brian could you explain the graph related to the subject video above....is it straight line, linear or square graph. Thank you
