MATHS IN PHYSICS-falling object

CONDITION[br]A ball falls from a height of 50 meters. After 1 second it is at 40 m, after 2 seconds at 20 m, and after 3 seconds it reaches 0 m.[br][br]TASK[br]Which mathematical model best describes the motion of the ball, and what does the decreasing height represent?

quadratic-like motion, acceleration due to gravity linear function, constant speed exponential growth, increasing speed upward exponential growth, increasing speed upward

MATHS IN CHEMISTRY-gas production

CONDITION[br]During a chemical reaction, gas is produced over time:[br]after 0 minutes = 0, after 2 minutes = 5, after 4 minutes = 12, after 6 minutes = 20.[br][br]TASK[br]What type of mathematical relationship best describes the gas production, and what does the increasing slope mean?

nonlinear increasing, accelerating reaction linear, constant production rate decreasing, slowing reaction constant, no reaction change
