Velocity time graphs Flashcards
1
Q
what does velocity time graphs show
A
they show the change in velocity over a period of time
2
Q
what is on the x and y axis
A
time is on the x axis and velocity is on the y axis
3
Q
what are the three things a velocity time graph can be used to determine?
A
- velocity in a point in time
- acceleration of the object
- displacement of the object
4
Q
what does positive slope show in a velocity-time graph
A
it shows an increase in velocity
5
Q
what does a negative slope show in a velocity-time graph
A
it shows a decrease in velocity
6
Q
what does a horizontal line show in a velocity-time graph
A
it shows a constant velocity
7
Q
the area under a velocity-time graph is equal to the ____________ of the object
A
displacement
8
Q
