## Vertical Projectile Motion in One Dimension (1D)

**(This section must be read in conjunction with the CAPS, p. 102–103.) **
**Explain** what is meant by a **projectile**, i.e. an object upon which the only force acting is
the force of gravity.
- Use
**equations of motion** to determine the position, velocity and displacement of a
projectile at any given time.
**Sketch** position versus time (x vs. t), velocity versus time (v vs. t) and acceleration
versus time (a vs. t) graphs for:

- A free-falling object
- An object thrown vertically upwards
- An object thrown vertically downwards
- Bouncing objects (restricted to balls)

**For a given** x vs. t, v vs. t or a vs. t **graph, determine**:
- Position
- Displacement
- Velocity or acceleration at any time t

**For a given** x vs. t, v vs. t or a vs. t **graph**,
**describe** the motion of the object:
- Bouncing
- Thrown vertically upwards
- Thrown vertically downward
