## What do you learn in Engineering Mechanics – Dynamics

Engineering Mechanics - Dynamics covers the motion of particles and rigid bodies. You'll learn about kinematics, force and acceleration, work and energy, and impulse and momentum. The course focuses on applying Newton's laws to analyze dynamic systems, understanding how forces affect motion, and solving problems involving moving objects in various reference frames.

## Is Engineering Mechanics – Dynamics hard?

Dynamics can be pretty challenging, not gonna lie. It builds on statics concepts but adds the complexity of motion, which can be a mind-bender at first. The math isn't too bad if you're solid on calculus, but visualizing 3D motion and choosing the right approach to solve problems can be tricky. Most students find it tougher than statics, but with practice, it clicks.
