Lesson goals:

- What is inertia

- Apply Newton's second

law of motion

Slide 3 - Slide

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^{​ r e s ​ ​} = m \cdot a

Slide 8 - Slide

F_res = resultant force (N)

m = mass (kg)

a = acceleration (m/s²)

F^{​ r e s ​ ​} = m \cdot a

Slide 9 - Slide

Definition of Newtons second law

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

1 kg by 1 m/s².
