Essential Question

How do forces cause changes in motion, and how can we describe and predict the movement of objects using mathematics?

What You Will Learn

• 1Describe motion using position, displacement, velocity, and acceleration.
• 2Interpret and draw position–time and velocity–time graphs.
• 3Apply the four kinematic equations to solve 1D motion problems.
• 4State and apply Newton's three laws of motion.
• 5Draw free-body diagrams and calculate net force.
• 6Resolve vectors into components and analyze projectile motion.

Why It Matters

Motion and forces are the foundation of all classical physics. From designing safe cars to launching satellites, every engineering application depends on understanding how objects move and why. Mastering this unit gives you the tools to analyze any mechanical system.
