# Mechanics: State, explain, analyse and apply principles of Newton’s first and second laws of motion

### Subject outcome

Subject outcome 2.4: State, explain, analyse and apply principles of Newton’s first and second laws of motion

### Learning outcomes

- Identity whether forces applied on a mass are balanced or not; and determine the net force.
- Define inertia and give examples.
- Define Newton’s first law of motion and relate to examples.
- Define and apply Newton’s second law of motion.
- Plan and conduct a scientific investigation to investigate the proportionality between mass and acceleration.
- Solve problems using Newton’s second law of motion on systems containing one and more than one object for horizontal and vertical motion.
