Dynamics

Dynamics is the study of the forces and their effect on motion.

Key Concepts:

• Newton’s Laws of Motion

• Free-body diagrams

• Friction, tension, and normal forces

Sample Question:

A 3 kg box is pulled with a force of 15 N. What is its acceleration?

\[a = \frac{F}{m} = \frac{15}{3} = 5\ \text{m/s}^2\]
