AP Physics 1 2025 Exam Questions (pdf)

1. A student has a cart of mass m_c and a block of mass 1/5 m_c, as shown in Figure 1. • At time t = 0, the cart is moving to the right across a horizontal surface with constant speed v_c, and the student releases the block from rest. • At t = t₁, the block collides with and sticks to the top of the cart. The block does not slide on the cart. • At t = t₂, the block-cart system continues to move to the right with constant speed v_f. …

2. A block of mass M is released from rest at position x = 0 near the top of a ramp. The ramp makes an angle of θ with the horizontal. The block slides down the ramp with negligible friction. At x = 8D the block makes contact with an uncompressed spring with spring constant k. The spring is then compressed and the block momentarily comes to rest at x = 12D. Figure 1 shows the instants when the block is at x = 0, x = 6D, and x = 10D, respectively. …

3. Students are investigating balancing systems using the following setup. The students have a spring scale of negligible mass that is fixed to one end of a uniform meterstick. The center of the meterstick is attached to a stand on which the meterstick can pivot. There is a hook of negligible mass fixed to the top of a block of mass m0. The hook can be attached to the meterstick through one of the small holes in the meterstick, as shown in Figure 1. The students do not have a direct way to measure the mass of the block. The block cannot be attached to the spring scale. …
