1) A ball rolls off the edge of the table. The horizontal component of the ball’s velocity remains constant during its entire trajectory because
A: the ball is not acted upon by a force in the horizontal direction. B: the net force acting on the ball is zero.
C: the ball is not acted upon by any force.
D: the ball is not acted upon by any force in the vertical direction.
E: None of the other choices are correct.
Answer: The answer is A because there’s no acceleration in the x direction when we deal with projectile motion. If the acceleration equals zero, then F = m*a has to be zero for the x direction.

The scale at the left is attached to the ceiling and a mass of 1.00 kg hangs from it. It reads 9.81 N. The identical scale at the right is connected by perfect springs passing over perfect pulleys to two 1.00 kg masses hanging vertically at the end of the strings. The scale at the right reads
A: exactly 19.62 N B: more than 19.62 N
C: more than 9.81 N
D: less than 9.81 N but quite twice as much
E: exactly 9.81 N
Answer: The answer is E because the scale at the left has gravity acting on the mass and the scale on the right also has gravity acting on the mass from the perfect pulley system. Since the scales and each side of the pulley are identical, it makes sense for both masses to have the same weight of 9.81 N.
3) A force produces power P by doing work W in a time T. What power will be produced by a force that does six times as much work in half as much time?
A: 12P B: 6P
C: 1/12 P
D: 3/8 P
E: 1P
Answer: The answer is A, 12P because you need to rearrange the power formula.
Final Tips
Approach these problems with the concepts in mind and consider whether the answer is plausible or just a ridiculous option meant to distract you. Once you narrow it down to the last two choices, go back to the problem and reread what’s being asked. Sometimes you can make a guess based on the context if you haven’t gotten the answer. If you don’t know how to solve the problem, you should guess using any clues from the units and questions to figure the answer out.
Key Terms to Review (14)
Acceleration
: Acceleration refers to the rate at which an object's velocity changes over time. It can be positive (speeding up), negative (slowing down), or zero (constant speed).F=ma
: F=ma is Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration.Force
: Force is a push or pull that can change the motion of an object. It is measured in Newtons (N).Gravity
: Gravity is a fundamental force that attracts objects with mass towards each other. It is responsible for phenomena such as planetary motion and keeping us grounded on Earth.Horizontal Component
: The horizontal component refers to the part of an object's motion or velocity that is parallel to the ground.Mass
: Mass refers to the amount of matter an object contains. It is a measure of the inertia or resistance to changes in motion.Net Force
: The net force is the overall force acting on an object, taking into account both magnitude and direction. It determines the object's acceleration or deceleration.Newton (unit)
: The Newton (N) is the unit used to measure force in the International System of Units (SI). One Newton is equal to one kilogram-meter per second squared (kg·m/s²).Power
: Power is the rate at which work is done or energy is transferred. It measures how quickly work is being done.Projectile Motion
: Projectile motion refers to the curved path that an object follows when it is thrown or launched into the air. It is influenced by both horizontal and vertical components of motion.Pulley System
: A pulley system is a simple machine that consists of a grooved wheel and a rope or cable. It is used to change the direction or magnitude of a force.Scale
: In physics, scale refers to the ratio of measurements on a model or diagram to the actual measurements of the object being represented. It allows us to represent objects that are too large or too small to be drawn at their actual size.Time
: Time is a fundamental quantity that measures the duration between events or actions. It helps us understand when things happen and allows us to compare durations.Work
: Work is the transfer of energy that occurs when a force is applied to an object and it moves in the direction of the force. It is equal to the change in kinetic energy of the object.AP Physics 1 Multiple Choice Questions
