Which term describes properties of how motion occurs within an object (no forces)?

• A. Kinematics
• B. Kinetics
• C. Velocity Equation
• D. Acceleration

Answer: (A)

The main idea is describing motion itself without worrying about what causes it. Kinematics focuses on where an object is, how fast it’s moving, and how its speed or direction changes over time, all without referencing forces. It uses displacement, velocity, and acceleration as the primary descriptors of motion, often through position–time or velocity–time relationships and graphs.

Kinetics would bring forces into the picture, explaining why motion changes, rather than just how it unfolds. The velocity equation isn’t a standard term for this concept, and acceleration alone is just one aspect of motion—a single descriptor—not the full description of how motion occurs.

So, the best fit for describing the properties of motion itself, with no forces involved, is kinematics.
