This is Physics 20 (grade 11)- Module 5 - Lesson 1 - Horizontal Circular Motion
Question 1 Circular motion is a special kind of motion. Consider each of the following theoretical questions Not yet answered related to HORIZONTAL CIRCULAR MOTION and choose the best answer from the options Marked out of provided. 3.00 Consider the following scenario: A ball is attached to a string. The ball is moved in a large Flag question horizontal circle at a constant speed. a) The string exerts a force on the ball. That force is b) Which of the following is true about the effect of the string's tension on the ball's motion --> c) If the string is cut, the ball willa) The string exerts a force on the ball. That force is Pulling outwards on the ball. Pushing sideways on the ball. t of th Pulling inwards towards the center of the circle. BOTH pulling inwards and pushing sideways on the ball. c) If the string is cut, the ball willb) Which of the following is true about the effect of the string's tension on the ball's motion Tension causes the ball's velocity to stay constant. C) Tension causes the ball's speed and direction to change. Tension does not affect the ball's velocity. Tension causes the ball's velocity to change.c) If the string is cut, the ball wi V continue moving in a circle. move in a straight line. move unpredictably depending on its mass.Question 2 In Module 5 Lesson 1, you were asked to examine the relationship between the RADIUS of a circle and the Not yet TENSION needed to produce circular motion. The lab activity is linked HERE and the notes/procedure are in the answered online lesson. Marked out of 3.00 Run the simulation, and adjust the radius to the values indicated in the following table. Record the Flag inward force (tension). Record your answers rounded to ONE DECIMAL PLACE. question Remember, mass = 2.0 kg and velocity = +5.0 m/s. Radius Inward Force (tension) (m) (N) 1.0 1.5 2.0 2.5 3.0 000 0 0 00 0 0 3.5 4.0 4.5 5.0Procedure Re-open the Circular Motion: Horizontal simulation, if necessary, and continue with the procedure. . Set the mass to 5.0 kg and the radius to 2.0 m. . Run the simulation, and adjust the initial velocity to the values shown in the table below.Question 3 a) Using the data from the lab activity (table of radius vs. inwards force), GRAPH the data Answer saved then upload a copy of the graph in the dropbox provided (1 mark) Marked out of 3.00 b) Based on the graph, state the mathematical relationship between inwards force and the Flag radius. question Paragraph B E ED a) See attached graph. b) Fc xQuestion 4 Run the simulation, and adjust the mass to the values indicated in the table below. Record the Not yet answered inward force (tension). Marked out of Remember, radius = 2.0 m and velocity = +5.0 m/s 3.00 Flag Mass Inward Force question (kg) (tension) (N) 1.0 2.0 3.0 4.0 5.0Question 5 a) Using the data from the previous question (mass vs. inwards force), draw the graph and Answer saved upload a copy in the dropbox provided. (1 mark) Marked out of 3.00 b) Referring to the graph, determine the mathematical relationship between the mass of an Flag object undergoing circular motion, and the inwards force required to cause circular motion. question (1 mark) Paragraph B in a) Please see attached graph. b) The relationship is: Fc a.Question 6 Let's apply what you've learned from the lab activities: Not yet answered Suppose you were to reduce the length of the string you are using to twirl the ball one-half. How Marked out of would that affect the size of the inward force (tension) in the string? 3.00 Flag The size of the new inwards force would be times the original force. question Suppose you were to increase the mass of the ball by five times. How would that affect the size of the inward force (tension) in the string? The new force would be times the original force. Suppose you want to speed the ball up by a factor of 2.5. By what factor must the radius increase in order to keep the inwards force (tension) the SAME? The radius would increase by a factor of For each of these questions, enter the numerical factor by which the original force/radius must increase/decrease, rounded to the second decimal place. For example if the new force is 1/3 of the original force, enter 0.33.Question 7 A 1200 kg car is making a turn through a 90 m radius turn on a road. The coefficient of friction Not yet answered between the car's tires and the road is 0.56. Marked out of Calculate the MAXIMUM speed the car can be travelling as it drives through this turn on the 2.00 road. Assume the car is moving in horizontal circular motion.
