# Mechanics: Identify, describe and apply principles of motion in one dimension

### Subject outcome

Subject outcome 2.1: Identify, describe and apply principles of motion in one dimension.

### Learning outcomes

- Describe motion and identify and define the components of motion, namely:
- position
- displacement and distance
- speed and velocity, including average velocity, instantaneous velocity and uniform velocity
- constant acceleration.

- Apply the concept of relative motion, i.e. motion quantities seen from two frames of reference.
- Do calculations on the components of motion.
- Solve problems using linear equations of motion (horizontal), namely:
- [latex]\scriptsize {{v}_{f}}={{v}_{i}}+a\Delta t[/latex]
- [latex]\scriptsize s={{v}_{i}}\Delta t+\displaystyle \frac{1}{2}a\Delta {{t}^{2}}[/latex]
- [latex]\scriptsize v{{_{f}^{2}}_{{}}}=v_{i}^{2}+2as[/latex].

- Define and represent vectors and scalars and identify examples.
- Define resultant and equilibrant and determine resultant and equilibrant by construction.
