AP Physics 1 Review - 1-D/2-D Kinematics Concepts

These flashcards cover key concepts and definitions related to 1-D and 2-D kinematics in AP Physics.

Kinematics

The branch of physics that describes motion in terms of position, velocity, and acceleration.

Instantaneous Velocity

The velocity of an object at a specific moment in time, represented as the slope of the position graph.

Instantaneous Acceleration

The acceleration of an object at a specific moment in time, represented as the slope of the velocity graph.

Uniformly Accelerated Motion

Motion with constant acceleration.

Free Fall

Constant-acceleration motion where the acceleration is due to gravity, represented as ay = g = -9.80 m/s².

Projectile Motion

The motion of an object where the only force acting on it is gravity, resulting in a parabolic trajectory.

Components of Motion

The independent x- and y-components of an object's motion in 2-D kinematics.

Turning Point

A point in motion where the object’s position is at a maximum or minimum, and the instantaneous velocity (vx) is zero.

Slope of Position-Time Graph

Represents the velocity in a velocity graph.

Acceleration Significance

The sign of acceleration (ax) indicates the direction of acceleration, not whether the object is speeding up or slowing down.

Uniform Motion

Motion with constant velocity and zero acceleration.

Acceleration due to Gravity

The rate of change of velocity of an object falling freely towards the Earth, approximately -9.80 m/s².

Direction of Motion

The sign of velocity (vx) indicates if the motion is positive (vx>0) or negative (vx<0).
