Why Things Move: The Kinematics & Forces Link

Ever wondered about the physics behind a perfectly curved free-kick or the G-forces on a rollercoaster? It's not magic; it's the elegant interplay of kinematics (the study of motion) and forces (the cause of motion). For IB DP Physics, mastering this connection is non-negotiable. This guide will help you bridge the gap between describing how objects move and explaining why they move. We will explore how:

• Newton's Laws are the fundamental 'why' behind any acceleration.
• Free-body diagrams can simplify even the most complex scenarios.
• Kinematic equations (SUVAT) are the direct result of applying a constant net force.
