On a speed time graph what measures acceleration?

Answer 1

deceleration can be measured from a velocity time graph by calculating the gradient of the velocity time graph if the V-t graph was linear.

If the v-t graph was a curve then the differentiatial of the equation of the curve will give the deceleration variation with time.

Answer 2

The magnitude of the acceleration at every instant is the slope of the graph at that instant.

The average acceleration over a period of time is the (difference in velocity during that time) divided by the (time).

Answer 3

Acceleration = velocity change / time

x axis = time , y axis = velocity

Acceleration at any point on a speed time graph:

= Gradient of a line tangential to the curve at that point

= vertical change (velocity change) / horizontal change ( time elapsed)

= velocity change / time

= acceleration

on a data driven graph, best guess the tangent.

on a equation graph, use differential calculus.

Answer 4

Acceleration on a speed-time graph is represented by the slope of the line. A steeper slope indicates a greater acceleration. If the slope is positive, it indicates acceleration; if it is negative, it indicates deceleration.

Answer 5

The slope at each point on a speed/time graph is the

magnitude of acceleration at that point in time.
