Study Notes
IB Middle Years Physics Practice Questions
- Grade: MYP IV
- Total Points: 93
- Authors: Taimur Abbas
Task 3 - Skiing Scenario
- Q 1.1: Label the weight (W) and normal force (N) acting on a skier.
- Q 1.2: Show the resultant force acting on the skier on a diagram copy.
- Q 1.3: Describe the effect of the resultant force on the skier's motion, referencing Newton's second law. (Net force causes acceleration; increasing speed downhill).
Task 3 - Velocity-Time Graph
- Q 1.4: Determine the acceleration at time t = 8.0 s. (Use the gradient formula: acceleration = (change in velocity) / (change in time). For example using points (6, 12) and (11, 0) for calculation).
- Q 1.5: Calculate the displacement in the first 5 seconds. (Use the area under the velocity-time graph using suitable segments).
- Q 1.6: State the time the skier started travelling back down the embankment. (Identify the point on the graph where the velocity becomes negative).
Cartoon Analysis
- Video Clip Analysis: The provided text discusses an experimental design, relating the film "UP" and calculations for floating objects. Questions ask for forces on balloons, calculating net force and upthrust.
Section 4 - Ball Drop Investigation
- Q 3.1: State a research question about the effect of changing the drop height of a ball on its velocity of impact. (Example: How does changing the drop height of a ball affect its velocity of impact?)
- Q 3.2: Formulate a hypothesis using scientific reasoning. (Example: If the drop height of the ball increases, its velocity at impact will also increase).
- Q 3.3: Design an experiment. Include independent (drop height), dependent (impact velocity), control variables (initial velocity, ball mass/shape), and method (measurements, repeating procedure).
- Q 3.4: Propose a second investigation, to determine another effect for the ball at impact. The new research question could be "How does changing the mass of the ball affect its velocity at impact?". Control variables would include drop height and initial velocity.
Task 3 - Spring Investigation
- Q 4.1: Design an experiment to investigate the effect of mass on the time period of oscillation. Include independent variable (mass), dependent variable (time period). Control variables (spring stiffness, initial displacement). Describe method.
Task 5 - Dead Sea Scheme
- Q 5.1: Discuss one advantage and one disadvantage of pumping water from the Red Sea into the Dead Sea (Example: Advantages: raising the Dead Sea water level; Disadvantages: potential disruption of water resources elsewhere).
- Q 5.2: Calculate the volume of water pumped into the Dead Sea. (Use formula. density = mass/volume)
- Q 5.3: Convert the Dead Sea surface area to m². (Units conversion, Example: 1 km² = 1000² m²)
- Q 5.4: Calculate the level rise of the Dead Sea yearly. (Assume no other losses).
- Q 5.5: Evaluate the scheme's effectiveness, considering the rise rate compared to the natural decrease rate. (Compare these values to understand, whether pumping works or not).
