Introduction to Projectiles

A-Level Mechanics: Introduction to Projectile Motion (20-slide PowerPoint Lesson)

This resource is a complete introductory lesson on projectile motion for A-Level Mathematics (Mechanics).

Rather than beginning immediately with equations, the lesson develops the physical ideas behind projectile motion in a visual and intuitive way. Students are introduced to the concept through a series of thought experiments, including throwing a stone horizontally from a building and Newton’s famous Cannonball thought experiment.

The lesson explains:

• Why projectiles follow curved paths.
• The relationship between parabolas and elliptical orbits.
• Why a parabola is an excellent approximation for ordinary projectile motion.
• The assumptions used in the standard mathematical model (flat Earth, constant gravity, negligible air resistance).
• The force acting on a projectile and the resulting acceleration.
• How projectile motion can be understood as two independent motions occurring simultaneously.
• The choice of reference frame and coordinate axes.
• The vector equations of motion for projectiles.
• The four scalar equations used in A-Level Mechanics.

The PowerPoint contains clear diagrams, progressive visual explanations and a fully worked introductory example involving a projectile launched at an angle.

This lesson is particularly suitable for:

• Edexcel A-Level Mathematics (Mechanics)
• AQA A-Level Mathematics (Mechanics)
• OCR A-Level Mathematics (Mechanics)
• Further Mathematics students requiring a conceptual introduction to projectiles

The resource is designed to help students understand the underlying physics before applying the mathematical techniques, making it ideal as a first lesson on projectile motion.
