1 (rearranged) and mathematically Questions 2. Which group of quantities below consists o of Multiple Choice Questions L. Match the general dlements of physics knowledge deft) with a) Average speed, displacement, time interval quantities (b) Average speed, path length, clock reading (c) Temperature, acceleration, position the appropriate examples (right) Free fall Acceleration Rolling ball Point-like object Model of a process Model of an object 3. Which of the following are examples of time intervala (1) I woke up at 7 am. (2) The lesson lasted 45 (3) Svetlana was born on November 26.(4) An a Physical quantity Physical phenomenon bited Earth in 4 hours. (a) 1,2, 3, and 4 (b) 2 and 4 (d) 4 (a) Model of a process-Acceleration: Model of an object- (c) 2 (e) 3 Point-Jike object: Physical quantity-Free fall; Physical phenomenon-Rolling ball 4. A student said, "The displacement between my dorm and (b) Model ofa process-Rolling ball: Model of an object- Point-like object: Physical quantity- Acceleration; lecture hall is 1 kilometer." Is he using the correct phy quantity for the information provided? What should bei Physical phenomenon-Free fall. called the 1 kilometer? (a) Distance (d) Both a and b are correct. (c) Model of a process-Free fall: Model of an object- Point-like object; Physical quantity-Acceleration; (b) Path length (c) Position Physical phenomenon-Rolling ballExplanation / Answer
Kindly post the other questions as separate problems. I have answered the first question here:
Model of a process is an activity with a defined object in consideration, like a rolling ball.
Model of an object is a specifically defined physical object for modelling a problem in physics, hence A point like object is the correct answer.
A physical quantity is a quantity in physics that can be measured and hence, Acceleration is the right answer.
A physical phenomenon is a process without mentioning the characteristics of an object hence, the answer is Free Fall.
