  • how come this video is under grade 12 but mr cope is putting this on our test tomorrow for gr 11.......

  • @cookiekekee It is in both. I need to change the grade on this one. Thanks for letting us know.

  • And frankly speaking,i am 13...Not 13th grade BUT the age of 13...and i studied the very basic of force...Like Net force frictional force...velocity etc...And based on the video you made,i understand EVERYTHING.

  • @phuajiawei Hi. Very good. Most 13 year olds have no idea how this works. Glad I could help you learn.

  • We dont see a reason why we must go to school...All we need is PhysicsEH!

  • @phuajiawei Thanks for that great comment. I hope my students don't see it.

see all

  • Is there a difference if the object is being pulled or pushed?

  • @PhysicsEH Thanks for the great videos. I wished I stayed in Toronto. I live an hour or so away depending on your location. It'd be nice if I had a physics teacher like you.

  • You are awsome! I used this to study a little for Physics. Reading gets so tiresome after a while, that you just lose interest.

  • Now i know that Canada is great.

  • I am a bit confused.Shouldn't the F21 force be negative since it's anti-parallel to the movement???Hoping for an answer.

  • Any videos on Newton's second law?

  • @phuajiawei eyyy me too

  • A 1.0kg toy car is moving across a smooth floor with a velocity of 5.0 m/s. An unbalanced force of 2.0N acts on the car for 4.0s. Determine the velocity of the car at the end of the interval in each of the following cases.

    A) if the force acts in the direction of motion of the car.

    B) if the force acts in the opposite direction to the motion of the car.

    CAN YOU HELP ME WITH THIS QUESTION??? PLZ!
