Distance-Time Graphs in GCSE Physics

The video tutorial explains how to describe motion using a distance-time graph. It covers key physics terms such as acceleration, constant speed, and stationary states. The tutorial identifies four distinct sections on the graph: acceleration (curved line upwards), constant speed (straight line upwards), stationary (flat line), and constant speed returning to the start (straight line downwards). Each section is explained in terms of how distance changes over time.

What are the key terms used to describe motion in physics?

• Acceleration, constant speed, at rest, deceleration

• Speed, velocity, distance, time

• Force, mass, acceleration, velocity

• Energy, power, work, force

• It indicates the object is at rest

What does a flat line on a distance-time graph indicate?

• At rest

• Constant speed

• Acceleration
