Practice and Revision - Motion
Let us practise and revise what we learned about motion. Motion describes the change in an object's position over time, and can be uniform (
Core concept
An object is in motion when its position changes relative to a fixed reference point over time.
How it works
Uniform motion means an object covers equal distances in equal time intervals, like a car moving at a constant speed.
Why it matters
Non-uniform motion means the speed changes, like a car accelerating or decelerating in traffic.
Key detail
Motion can be described using distance-time graphs, which visually show how an object's position changes over time.

Quick notes
• Motion is a change in position over time.
• It's measured relative to a fixed reference point.
• Uniform motion has constant speed.
• Equal distances covered in equal time.
• Non-uniform motion has changing speed.
• Example: a car accelerating in traffic.
• Distance-time graphs show motion visually.
• Motion is fundamental to understanding physics.
