AP Physics 1 MCQ Questions With Correct Answers
Graded A+
The amusement park ride shown above takes riders straight up a tall tower and then releases an
apparatus holding seats. This apparatus free-falls back to Earth and is stopped safely right above
the ground. Which of the following indicates the magnitude of the gravitational force exerted on
a rider of mass m on the way up and on the way down?☑️Correct Ans-Way Up = Equal to mg
Way Down = Equal to mg
Identical spheres are dropped from a height of 100m above the surfaces of both Planet X and
Planet Y. The position of the spheres as a function of time is recorded as the spheres fall. These
data are shown in the graphs above. Which planet exerts a greater gravitational force on the
sphere, and what evidence supports this conclusion?☑️Correct Ans-Planet Y, because the
magnitude of the slope of the curve increases at a faster rate.
Two identical blocks, block A and block B, are placed on different horizontal surfaces. Block A
is initially at rest on a smooth surface, while block B is initially at rest on a rough surface. A
constant horizontal force of magnitude F0 is exerted on each block. After the force has been
applied for a time Δt, the speeds of blocks A and B are vA and vB, respectively. Which of the
following claims indicates the correct relation between vA and vB and provides the best
justification for the relation?☑️Correct Ans-vA>vB. The forces between the atoms in a block
and the atoms in a surface oppose the motion of the block and are greater, on average, for block
B.
Which of the following experiments could be used to determine the inertial mass of a
block?☑️Correct Ans-Use a spring scale to exert a force on the block. Measure the acceleration
of the block and the applied force.
, A 1500kg car traveling along a road is hit by a 0.1kg rock that creates a small crack in the car's
windshield. Which of the following describes the interaction between the windshield and the
rock?☑️Correct Ans-The car exerts a force on the rock, and the rock exerts a force on the car.
The two forces are equal in magnitude.
Two objects, X and Y, move toward one another and eventually collide. Object X has a mass of
2M and is moving at a speed of 2v0 to the right before the collision. Object Y has a mass of M
and is moving at a speed of v0 to the left before the collision. Which of the following describes
the magnitude of the forces F the objects exert on each other when they collide?☑️Correct Ans-
The force exerted by X on Y is F to the right, and the force exerted by Y on X is F to the left.
A block is placed on an inclined plane and remains stationary, as shown in the figure above. A
student claims, "The block remains stationary because as gravity tries to pull the block down the
ramp, the block exerts an equal and opposite force on itself up the ramp." Is the student's claim
correct? Justify your answer.☑️Correct Ans-No. Newton's third law states the block cannot
exert a force on itself.
Students connect a spring scale to a block on a rough horizontal surface. The students use the
spring scale to measure the magnitude of the horizontal force needed to pull the block at a
constant speed. Which of the following statements explains why two forces exerted between
objects are equal in magnitude?☑️Correct Ans-The frictional forces that the block and the
surface exert on each other, because objects always exert forces of equal magnitude on each
other.
A spring-loaded launcher has a mass of 0.60 kg and is placed on a platform 1.2m above the
ground. The force of friction is negligible between the platform and the launcher. The launcher
