When it comes to learning vocabulary in creative ways, Quizlet is one of the leading, must-use platforms to prepare for the AP Exam. While it is accessible and flexible to any learning style for every subject, it can be hard to find a reliable Quizlet deck in a haystack of thousands of options.

For your convenience, we've put together some of the best Quizlet decks for AP Physics 1 for each unit to help you study for the exam. Check them out and enjoy our best picks!

Kinematics features the fundamental concepts of classical physics, which means that you need to understand the components of motion: velocity, acceleration, displacement, graphical analysis, and related ideas.

Most important terms to know:

**Velocity:Β**the**Speed:**Β commonly confused with velocity, how fast an object is traveling without a specified direction; it is a scalar quantity because only a number is associated with the measure.**Free Fall:Β**an object is under the influence of the force of gravity only; air resistance is negligible in this case.

Unit 2 starts with Newtonβs laws and zeroes in on the relationship of forces on interacting objects. Key players in this unit include the applications of contact forces, free-body diagrams, and conceptual ideas behind action-reaction pair forces.

Most important terms to know:

**Newtonβs First Law:Β "**An object at rest will stay at rest unless acted upon by a net external force. Likewise, an object moving at a constant speed will continue moving unless acted upon by an external force."**Frictional Forces:**Β the force exerted when an object moves across a surface (resists motion); friction always resists motion in a parallel direction to the surface.**Air Resistance:**a type of frictional force acting upon objects as they travel through the air; since the force due to gravity is always downwards, the object slows down if air resistance is in the upward direction.

Diving deeper into dynamics, this unit focuses on centripetal acceleration, circular motion, and gravity. By the end of this unit, you'll know how to calculate the amount of force causing the centripetal motion and understand the concepts behind gravityβs impacts on objects in motion.

Most important terms to know:

**Uniform Circular Motion:**Β an object travels along a circular path along an external axis, where the speed remains constant but the object can accelerate; the object can accelerate with constant speed because there is a change in direction.**Gravitational Mass:Β**the amount of matter that measures an objectβs response to gravitational force (inertial mass measures an objectβs resistance to any force).**Frequency:**Β the number of cycles a revolving object can complete within a certain amount of time, measured in Hertz per second, and is the inverse of a period (amount of time it takes for an object to complete one full cycle).

Here, the relationship between work, power, and energy on open and closed systems is further explored. In addition, potential and kinetic energy, along with their real life applications, fall under this unit.

Most important terms to know:

**Law of Conservation of Energy:**Β "Energy cannot be created nor destroyed but can be converted into different forms from one form" (i.e. potential and kinetic).**Mechanical Energy:**Β the energy possessed by an object based on its position or ability to do work; can either be potential or kinetic energy.**Closed Energy System:**a system in which no energy can from external sources enter and no energy from the inside can escape outside; internal forces donβt affect the conservation of energy.

This unit discusses momentumβs relation with force and time, which includes using the Law of Momentum Conservation to interpret scenarios. Other concepts make an appearance throughout the unit, such as the analysis of open and closed systems as well as impulse.

Most important terms to know:

**Angular Momentum:**the**Β**amount of rotation an object undergoes - a product of its moment of inertia and angular velocity.**Elastic Collision:Β**a**Impulse Momentum Theorem:Β**"The impulse is equal to the change in momentum where the impulse is a vector and the momentum is equal to the mass times the velocity of an object."

Unit 6 introduces a new type of motion in which oscillations of an object are proportional to the equilibrium displacement from a given position. This unit also covers the energy and period of simple harmonic motion.

Most important terms to know:

**Spring Constant:Β**the**Elastic Energy:Β**occurs when an object, typically a spring, is stretched or compressed; describes the mechanics of solid bodies and materials.**Amplitude:Β**the

The central ideas of this unit are rotational motion and its cause (torque). Youβll use the concepts of angular momentum, prior kinematics knowledge, and torque to traverse through this unit.

Most important terms to know:

**Conservation of Angular Momentum:Β**"If no external torque acts on the rotating system, then the angular momentum of that system is constant."**Torque:Β**the**Angular Acceleration:**the

AP Physics can be difficult at times, especially when it seems like there are several new formulae being procured from thin air. By focusing on the foundations of each unit and then building your understanding from the roots in the form of vocabulary sets and example problems, you'll be more successful in grasping the material.

Remember, understand the concepts and work on grasping the mathematics. Keep working hard, you can do it!
