Study Notes
Types of Motion
- The simplest type of motion is rectilinear motion, which is motion in a straight line.
Speed
- Speed is defined as the distance traveled per unit of time.
- Speed is a scalar quantity, which means it has only magnitude, not direction.
Converting Speed Units
- To convert speed from km/h to m/s, multiply by 0.277778 (since 1 km = 1000 m and 1 hour = 3600 s).
Acceleration
- If an object's speed increases as time decreases, it means the object is accelerating.
Types of Speed
- Uniform speed refers to motion at a constant rate, meaning the speed remains the same over time.
