In physics, motion occurs when an object changes position over time. Explore the types of motion called linear, projectile, circular, and simple harmonic motion, and learn about velocity.

Motion can be classified by the path that a moving object follows. Explore the different types of motion, such as linear motion, rotary motion, and oscillatory motion.

Learn how to compare the kinematic equations for linear and rotational motion and see examples that walk-through sample problems step-by-step for you to improve your physics knowledge and skills.

Master the complexities of kinematics of human motion in our quick video lesson. Watch now to gain insights into the mechanics of body movements, then take a quiz.

In linear motion, Newton's second law of motion states that the acceleration of an object is directly proportional to the net force applied to it but inversely proportional to mass.

Oct 10, 2025 · Rotational motion is characterized by angular quantities such as angular displacement, angular velocity, and angular acceleration, which are analogous to their linear counterparts.

Learn how to calculate the linear speed of an object in circular motion, and see examples that walk through sample problems step-by-step for you to improve your physics knowledge and skills.

Linear velocity is the speed and direction of an object moving in a straight line, measured in meters per second. Rotational velocity is the rotation rate of an object, measured in radians per second.

Explore the concept of linear velocity with this educational video lesson. Watch now to master the formula and calculation methods, followed by a quiz.
