Study Notes
Motion in One Dimension
- Motion in one dimension refers to an object moving along a straight line, with its position defined by a single coordinate.
Calculating Average Speed
- The formula for calculating average speed is: average speed = total distance travelled ÷ time taken.
Non-Uniform Motion
- Non-uniform motion occurs when an object's velocity changes, resulting in acceleration or deceleration.
- An example of non-uniform motion is a car accelerating from 0 to 60 km/h in 10 seconds.
