what is the formula of force (Newton's 2nd law)?
|
ZF = M x A M = ZF : A A = ZF : M |
|
|
Examples of Newton's 2nd law
|
1. when the car in the traffic jam, the velocity is change 2. when the car in the highway, the velocity is change |
|
|
What is friction? What is ZF in Friction?
|
the force that arise when an object intersects / contact with other object ZF = F - f |
|
|
Friction is divided by 2 and mention also the formula of both friction!
|
Static Friction (Friction when the object at rest) Formula = fs = Ms x N Kinetic Friction (Friction when the object move) Formula = fk = Mk x N |
|
|
ZF, N, W FORMULA
|
ZF = 0 N - W = 0 N = W N = M x G |
|
|
The sounds of Newton's 3rd law
|
For every action there is an equal and opposite reaction
|
|
|
Example of Newton's 3rd law
|
1. when you bunch a wall with your hand and the wall will give back the force so your hand will be hurt 2. when you ride a skateboard and you hit the wall than the wall will give you back a force so you will reflected |
