How Does the AP Physics 1 Differ from the AP Physics 2 Exam?

AP Physics 1 introduces algebra-based fundamentals, while AP Physics 2 demands a stronger math background for exploring complex topics. Both entail hands-on labs and similar exams, but AP Physics 2 necessitates a deeper math foundation.

AP Physics 1 focuses on basics like motion, waves, and simple circuits, suitable after completing geometry and Algebra II. Its three-hour exam mixes multiple-choice and free-response questions, allowing calculators and physics formulas.

AP Physics 2 delves deeper into heat, fluids, magnetism, and nuclear physics, requiring prior study of AP Physics 1 or similar courses and proficiency in precalculus. Labs and exam format mirror AP Physics 1, but with more challenging content.

Breakdown of Sections and Questions on the AP Physics 1 Exam?

1. A cart on a horizontal surface is attached to a spring. The other end of the spring is attached to a wall. The cart is initially held at rest, as shown in Figure 1. When the cart is released, the system consisting of the cart and spring oscillates between the positions x = + L. Figure 2 shows the kinetic energy of the cart-spring system as a function of the system,’s potential energy. Frictional forces are negligible.

a) On the graph of kinetic energy K versus potential energy U shown in Figure 2, the values for the x-intercept and y- intercept are the same. Briefly explain why this is true using physics principles.

When the cart is at +L and momentarily at rest, a block is dropped onto the cart, as shown in Figure 3. The block sticks to the cart, and the block-cart-spring system continues to oscillate between -L and +L. The masses of the cart and the block are m0 and 3m0, respectively.

b) The frequency of oscillation before the block is dropped onto the cart is f1. The frequency oscillation after the block is dropped onto the cart is f2. Calculate the numerical value of the ratio f2/f1.

c) The dashed line in Figure 4 shows the kinetic energy K versus potential energy U of the block-cart-spring system after the block is dropped onto the cart. This graph is identical to the graph shown in Figure 2 for the cart-spring system before the block is dropped onto the cart.

i. Briefly explain why the two graphs must be the same using physics principles.

ii. After the block is dropped onto the cart, consider a system that consists only of the cart and the spring. In Figure 4, sketch a solid line that shows the kinetic energy of the system that consists of the cart and the spring but not the block after the block is dropped onto the cart.

When two other solid spheres of radius 3R made of this steel are placed in contact, what is the magnitude of the gravitational force that they exert on each other?

3. The figure above shows three resistors connected in a circuit with a battery. Which of the following correctly ranks the energy E dissipated in the three resistors during a given time interval?

4. A 2-kilogram mass is attached to a spring with a spring constant of 400 N/m. If the mass is displaced 0.1 meters from its equilibrium position and released, what is the frequency of the resulting oscillation?

5. Two objects with masses of 5 kg and 10 kg are connected by a rope over a pulley. If the system is released from rest and the 5 kg mass falls 2 meters in 1 second, what is the coefficient of kinetic friction between the 5 kg mass and the surface?

6. A 0.5-kilogram block is pushed against a spring with a force of 20 newtons, compressing the spring by 0.1 meters. If the spring constant is 200 N/m, what is the maximum velocity of the block when released?

7. An object is launched vertically upward with an initial velocity of 20 m/s. Ignoring air resistance, how high does the object travel before it begins to fall back down?

8. A car travels around a curve with a radius of 50 meters at a constant speed of 20 m/s. What is the magnitude of the car's acceleration?

9. A 0.2-kilogram ball is thrown horizontally off a 10-meter-high cliff with an initial velocity of 15 m/s. How far from the base of the cliff does the ball land? Assume no air resistance.

FAQs

Let’s take a look at some commonly asked questions.

1. Is Calculator Use Permitted on the AP Physics 1 Exam?

On the AP Physics 1 exam, you are allowed to use a calculator, specifically four-function, scientific, or graphing types. Make sure to check that your calculator is on the approved list.

You can bring two calculators, but they must be checked by the proctor for compliance. You don't have to clear their memory. However, sharing calculators, using them to communicate, or trying to cheat with them is prohibited. If you opt not to use a calculator, you'll need to

2. How Is AP Physics 1 Scored?

The AP Physics 1 exam is scored on a scale from 1 to 5, with the total possible raw points being 95. This raw score is then scaled down to the 1 to 5 range, where a score of 5 indicates excellent understanding and readiness for college-level physics, and a score of 1 suggests a need for further study.
