Second law of Newton (5.3)

Lesson goals:

- What is inertia

- Apply Newton's second

   law of motion

Inertia

An object with a greater mass opposes changes in in motion. This means that:

-  An object accelerates slower

- An object needs more time to slow down

- An object has more difficulty to change 

   its direction

 

Newtons second law

The second law of newton explains the relationship between:

_{The resultant force, mass and acceleration}

F​res​​=m⋅a

F_res  =    resultant force    (N)

m       =    mass                        (kg)

a         =   acceleration         (m/s²)

F​res​​=m⋅a

Definition of Newtons second law

1N is the foce needed to accelerate an object with a mass of

 1 kg by 1 m/s².
