## 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.
