Uniform Motion and Kinematics
Learning Objectives
- Students will understand constant velocity motion
- Students will apply kinematic equations for uniform motion
- Students will distinguish uniform from non-uniform motion
Core Concepts
- Uniform motion: constant velocity (zero acceleration)
- Linear relationships between position and time
- Motion at constant speed in a straight line
Formulas
$$x = x_0 + vt$$
Position at time t for uniform motion starting at x₀
$$\Delta x = vt$$
Displacement for uniform motion
Interesting Fact
Newton's first law states that uniform motion is the natural state (no forces needed)
Key Scientist
Isaac Newton
First law: objects in uniform motion remain in motion unless acted upon
Modern Research
Inertial measurement units (IMUs) in smartphones and vehicles rely on detecting deviations from inertial motion to measure acceleration.
