Card preview (8)
what does velocity time graphs show
they show the change in velocity over a period of time
what is on the x and y axis
time is on the x axis and velocity is on the y axis
what are the three things a velocity time graph can be used to determine?
• velocity in a point in time • acceleration of the object • displacement of the object
what does positive slope show in a velocity-time graph
it shows an increase in velocity
what does a negative slope show in a velocity-time graph
it shows a decrease in velocity
what does a horizontal line show in a velocity-time graph
it shows a constant velocity
the area under a velocity-time graph is equal to the ____________ of the object
displacement
what formula is used to calculate displacement
