What is a distance-time graph?

A graph that shows how far an object has traveled in a give time

What does the gradient of a distance-time graph show?

Speed

What is the formula linking speed, distance & time?

Speed = distance ÷ time

What is the formula linking acceleration, change in velocity & time taken?

Acceleration = change in velocity ÷ time taken

What is a velocity-time graph?

A graph that shows how an objects velocity changes over time

What does the gradient of a velocity-time graph show?

Acceleration

What does the area underneath a velocity-time graph show?

Distance traveled in that time interval

What is the formula linking final speed, initial speed, acceleration & distance traveled?

final velocity² = initial velocity² + (2 × acceleration × distance traveled)

v² = u² + 2as

What is acceleration?

Speed increasing with time

What is deceleration?

Speed decreasing with time

What is velocity?

The speed of an object in a given direction

What is displacement?

The distance traveled from a specific starting point in a specific direction (the most direct route)
