Topic 4: Non-uniform Motion & Acceleration

Question 1

acceleration

Answer 1

change in velocity of object during a time interval, vector quanity
change: increase/decrease in magnitude (size/amount) of object’s velocity OR change in direction
displacement-time graphs

Question 2

non uniform displacement time graphs

Answer 2

curved
accelerating: velocity increases, bends towards right
decelerating: velocity decreases, bends towards up

Question 3

slope & area under velocity time graph

Answer 3

slope: acceleration
area under: displacement from original position
