Download Vertical Projectile motion problems with solutions for Grade 12 on pdf The vertical motion of a projectile is controlled by the force of gravity. This means that there is an unbalanced force. Eg: With a thrust of 20 N and an opposing frictional force of 15 N, the object experienced an unbalanced force of 5 N in the direction of the 20 N force.
Vertical Projectile motion
In Grade 12 Physical Sciences (Physics) we study the motion of objects that are moving upwards or downwards while experiencing a force due to gravity. This process is called projectile motion. We will only consider the case where objects move vertically upwards and/or downwards – meaning that there is no horizontal displacement of the object, only vertical displacement.
Main Vertical Projectile motion problems
When dealing with Projectile motion, students in Grade 12 should ensure they solve the following problems:
- 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 graphs for position vs time (x vs t), velocity vs time (v vs t) and acceleration vs time (a vs t) for each of the following: o A free-falling object.
- An object thrown vertically upwards
- An object thrown vertically downwar
- Bouncing objects (restricted to balls).
- For a given graph for x vs t, v vs t or a vs t, determine the following: o Position
- 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 for the following: o Bouncing.
- Thrown vertically upwards.
- Thrown vertically downwards.
