What is the formula to find the distance travelled in the vertical component?
Distance = velocity × time
This formula applies to both horizontal and vertical components.
What are the key time intervals mentioned for calculating distance in the vertical component?
0.0 to 0.2 s, 0.2 to 0.4 s, 0.4 to 0.6 s, 0.6 to 0.8 s, 0.8 to 1.0 s, 1.0 to 1.2 s
These intervals are used to analyze motion in segments.
What is the significance of the area under the curve in pharmacokinetics?
Determines bioavailability
The area under the curve is crucial for understanding how much of a drug reaches systemic circulation.
What are the parameters that determine the shape of the pharmacokinetic curve?
- Rate of dissolution of the tablet
- Rate of transfer from stomach to plasma
- Rate of excretion
These parameters influence how quickly a drug is absorbed and eliminated.
What is an analogy used to describe pharmacokinetics?
Filling a bath with hot/cold taps without a plug
This analogy illustrates the dynamic balance of drug absorption and elimination.
What does the maximum concentration in pharmacokinetics indicate?
Critical to avoid overdose
Monitoring maximum concentration helps prevent adverse effects of drug overdose.
In the context of motion, how is calculus applied?
To analyze distance, velocity, and acceleration
Calculus provides the tools needed to model and understand motion mathematically.
What is the initial velocity of the vertical component when throwing a ball?
10.0 ms^-1
This initial velocity affects how high the ball will rise before falling back down.
What is the acceleration due to gravity in the vertical motion of a thrown ball?
-10.0 ms^-2
This negative value indicates that gravity is acting downward on the ball.
What is the formula for finding acceleration?
Acceleration = change in velocity / time
This formula helps in determining how quickly an object’s velocity changes.
What does raising the power of a term by 1 and dividing by the new power calculate?
Area under the curve
This method is part of integration in calculus.
What is the equation of motion for height against time?
y = 10x - 5x^2
This equation represents the parabolic trajectory of an object under the influence of gravity.
How is the turning point of a plot of height against time determined?
Where the slope equals 0
The turning point indicates the maximum height reached by the object.
What does the average of two velocities multiplied by time represent?
Area of trapezium
This calculation is used in finding distance when velocity changes over time.
Fill in the blank: The area under the curve is proportional to _______.
bioavailability
This relationship is crucial in pharmacokinetics for understanding drug absorption.
What does R² = 1 indicate in a plot of height against time?
Perfect correlation
It shows that the model accurately represents the observed data.
What is the horizontal velocity when throwing a ball across the room?
5 ms^-1
This constant velocity is independent of vertical motion.
What is the formula to calculate height using trapezium areas?
Height = Sum of areas
This method involves calculating the areas of trapeziums formed on a velocity-time graph.
What is the average of two velocities used for in motion analysis?
To calculate the height during a given time interval
This is part of approximating the distance travelled when velocity changes.
