P2 1 Distance And Velocity Time Graphs Flashcards
Distance time graph characteristics
Stationary- horizontal line
Constant speed- a straight line which slopes upwards
Gradient- shows object’s speed
What is the distance, time and speed relationship?
Distance = time x speed
What is velocity?
Velocity is speed in a given direction.
What is acceleration?
Acceleration is the change of velocity per second. The unit is m/s^2
How do you work out the acceleration?
Acceleration = change of velocity / time taken.
What is deceleration?
Deceleration is the change of velocity per second when an object SLOWS down.
Characteristics of a velocity time graph
Horizontal line- acceleration is zero ( either constant speed or stationary)
Gradient- acceleration
Area under the line- distance travelled
