acceleration Flashcards
1
Q
what is acceleration
A
the rate velocity changes over time
2
Q
what is the equation for acceleration
A
a= final velocity- initial velocity/ time
3
Q
what does it mean when there is a flat line on a velocity-time graph
A
constant speed/ no acceleratio
4
Q
what does it mean when there is a increasing line on a velocity-time graph
A
positive accelation/ increasing speed
5
Q
what does it mean when there is a negative line on a velocity-time graph
A
decreasing speed/ negative acceleration
