Movement & Position - Edexcel IGCSE Physics

These flashcards cover key vocabulary and concepts from the Edexcel IGCSE Physics lecture on movement and position.

Distance-Time Graph

A graph showing how the distance of an object varies over time.

Constant Speed

Represented by a straight line on a distance-time graph; indicates uniform motion.

Slope

The gradient of a line on a graph, representing speed in a distance-time graph.

Changing Speed

Represented by a curve in a distance-time graph, indicating acceleration or deceleration.

Gradient Formula

Formula to calculate speed: speed = gradient = ∆y/∆x.

Instantaneous Speed

The speed of an object at a specific moment in time.

Average Speed

The total distance traveled divided by the total time taken.

Acceleration

The rate of change of velocity over time.

Formula Triangle

A visual tool used to rearrange equations based on quantity relationships.

Velocity-Time Graph

A graph showing how the velocity of a moving object varies with time.

Displacement

The change in position of an object, represented by the area under a velocity-time graph.

Uniform Acceleration

Constant acceleration; when the speed changes at a uniform rate.

Deceleration

A decrease in velocity; negative acceleration.
