18
Q

Learn acceleration time graphs and their meanings

A

Did you get it right ? (Acceleration graphs for now can only be horizontal lines) 

19
Q

What values can you get from a position time graph and how

A

Gradient = velocity = △x/ △t

20
Q

What values can you get from a velocity time graph and how

A

Gradient = acceleration = △v/ △t
And
Area under graph = distance = lxb + 1/2bh

21
Q

What values can you get from an acceleration time graph and how

A

Area under graph = velocity = lxb

22
Q

What are the three equations of motion

A

△x = Vi △ t+ 1/2a △t^2 (no Vf)
Vf^2 = Vi^2 + 2a △x (no △t)
Vf = Vi + a △t (no △x)
