Projectile Launcher with Base

This classic-style Projectile Launcher with Base is a versatile and durable piece of science equipment designed for physics classrooms and labs. Built on a solid timber base, the launcher features an adjustable arm with multiple spring tensions, enabling students to explore projectile motion with a range of angles and velocities. Capable of launching marbles up to 6 metres, it offers hands-on learning opportunities for investigating the principles of motion, energy transfer, and kinematics. The integrated protractor allows precise adjustment between 0 ° and 90 °, and the flat base accommodates photogate timing systems for advanced motion studies. Its robust construction ensures it stands up to frequent classroom use while offering a safe and engaging method for exploring core physics concepts.

Educational benefits:

• Demonstrates Newtonian motion, velocity, acceleration, and projectile trajectories
• Supports investigations into the effects of launch angle and spring constant on distance
• Introduces students to experimental measurement and controlled variable testing
• Enhances understanding of energy conservation and kinetic energy transfer
• Provides a tactile and visual demonstration of theoretical physics equations

Classroom application ideas:

• Use to explore optimal angles for maximum projectile range (e.g. 45 °)
• Conduct experiments comparing launch distances with different spring settings
• Pair with photogate sensors for precise timing and speed measurements
• Explore the relationship between angle, speed, and vertical vs horizontal displacement
• Engage students in collaborative design challenges (e.g. target hitting contests)
