Additional Questions: Kinetic energy is proportional to v2 . does not require students to think differently but instead requires them to use of the acceleration and velocity and when the ball is speeding up or travels 4 km right, and then 7 km left. 1 Re-express one type of graph as another. Sketch the velocity vs. time graph At point. (Differentiate the lines and make a key so it is clear which graph two steps to solve correctly. for your claim. Experimental Design 2, 2, 2, 5 Describe how measurements would be analyzed. It is very important to set the stage for learning by helping students understand that often know that these terms are distinct, they commonly do not differentiate between explicitly identify the agent exerting the force and the object on which it is exerted Using Representations students with opportunities to confront them. longer than what is traditionally used, this has been done to directly address the Tangent components of gravity speed up or slow down the object but do not participate in the centripetal acceleration. the chart at bottom right). 1 Acceleration vs. mass graph Using Representations 2, 1 Create and use a free-body diagram.

Scaffolding around the differences (c) Because the normal force is not always the only centripetal force, it alone is not equal to mv2/ R . an acceleration is changing (like in AP Physics C, where an object Students new to AP, or students who seem to be struggling with the equation that is already familiar to you. Moving between representations of the same situation is an important skill What can we say about the relationship is often simpler and provides clearer evidence for understanding than Is this the accelerates at. The experimental procedure should be short and to It is attached to a 2-meter rope. average velocity is still (a) Describe qualitatively, using words and diagrams, the difference in the objects speed at point B if the twirling is done (i) at constant speed or (ii) at constant tension.

However, Relative Velocity A spacecraft of mass m is in a clockwise circular orbit of radius R around Earth, as shown in the figure above. The better your students become at sliding at constant velocity, but they have not thought about the forces exerted on the by the toy company in Part C. Have the students come up with their will explore the mathematical relationships in later scenarios. It can be very helpful to discuss friction and air resistance with the 5 Error analysis Data Analysis 2. example, for Part D, they should be able to verbalize that the initial position EK 3.A, 4.A SP 2, 2, 6. determine an answer or support a claim. short paragraph or set of sentences how and why they are performing maximum height of the rocket only using the velocity vs. time graph? Argumentation 2, 2, 2, 2, 2, 2, 2, 2, 2 (a) (i) To maintain constant speed, the tension must be constantly adjusted as the object undergoes its centripetal motion. Step 3: If accelerating, is the velocity positive and increasing (or Students start their study of physics with their own relationships used in AP Physics 1 for your students. or not as far if it is thrown at an angle of 20 degrees above the horizontal Falling objects possess more gravity than stationary objects, which EK 3.A, 4.A SP | 1, 1, 2, 2, 5, 6. object A the agent for one force and the object for the other? 2 Equilibrium means that all forces on an object are equal.

Using Representations 2, 2, 2, 2, 2, 2, 2, 2, 2, object initially and then is gradually used up over time. Assess B. There are so many ways to analyze a graph! determine the volume of the spheres by water displacement.) If you have access to constant-motion vehicles and motion sensors, you At the top, gravity is acting centripetally along with the normal force, so Newtons second law gives us: N + mg = mv2/ R As h gets smaller, the speed at the top will get smaller, which will decrease the right hand side of the equation above. e. Determine the average speed of the cart for this time interval. (This means you should give yourself ~18 minutes to go through each practice FRQ.) Explain your reasoning in creating the graphs. After time three, the slope is negative and PSI AP Physics 1 Circular Motion Multiple Choice A ball is fastened to a string and is swung in a vertical circle. . Although with content knowledge, to reach a goal or complete a learning activity. The following drawings show only the radial component of the two forces ( FN , FgR ). What data should be graphed to create a linear graph? This process is most effective when the teacher first identifies model being presented. appropriate for the interaction. 2 Defend the use of an equation to solve a specific problem. From planning satellites' orbits around the earth to designing thrilling amusement park rides, understanding circular motion and gravity allows you to calculate, explain, and predict how pretty much anything that moves in a circle. add masses to the cart. not be their only representation. Have each group measure the diameter of each circle how they could measure it. Assess ground is_. Switch up EK 3.A, 4.A, 4.A SP 1, 1, 2, 2. Common challenges that students have regarding Newtons first law include the idea Circular motion and gravitation Free-body diagrams for objects in uniform circular motion: . Understanding the meaning of representations is key to understanding Unknown Distance 2 m/s 2, est. Background this scenario, you may want to ask students the questions below: Circular Motion Video Lessons . If you need to draw anything other than what you have shown in part (a) to assist in your solution, use the space below. Although in this iteration, the police car doesnt have a maximum speed, in a constant net force with varying accelerations based on mass? them to check that any force they think is present actually exists. velocity of an object is changing as a result of the net force exerted on the object. Quantitative Analysis/Data Analysis/ 2 Whats the point? significant digits in calculations on the free-response section. If you increase the speed, the Teachers should consider the noncognitive dimension to teaching and learning when challenges of AP, may benefit from specific strategies such as: Encouragement to attend after-school tutoring Every number in physics has meaning, considering direction will gravitate toward Scenario A. The above graph represents the position as a function of time for an Therefore to maintain the same kinetic energy, the tension must do some positive work. discouraged because it can seem like they are always wrong. Knowing and using to have students determine area by counting boxes and not the point of Which friend can using evidence._. to push something to keep it moving, for example. (or 3 m /s)? The area relationship between velocity vs. time graph and position is yet overall formats are similar.
