Motion in Physics

Types of Motion

• Translational Motion: An object moves from one point to another in a straight line or a curved path.
• Rotational Motion: An object rotates around a fixed axis, such as a wheel rotating around its center.
• Oscillatory Motion: An object moves back and forth repeatedly, such as a pendulum swinging.
• Vibratory Motion: An object oscillates about a fixed point, such as a guitar string vibrating.

Describing Motion

• Position: The location of an object in space, described by its coordinates (x, y, z).
• Displacement: The distance an object travels from its initial to its final position.
• Velocity: The rate of change of an object's position, described by its speed and direction.
• Acceleration: The rate of change of an object's velocity, described by its magnitude and direction.

Motion in One Dimension

• Distance: The total length of an object's path.
• Speed: The distance traveled per unit time.
• Velocity: The rate of change of an object's position, with direction.
• Acceleration: The rate of change of an object's velocity, with direction.

Motion in Two and Three Dimensions

• Projectile Motion: The motion of an object under the influence of gravity, such as a thrown ball.
• Circular Motion: The motion of an object moving in a circular path, such as a car turning a corner.
• Relative Motion: The motion of an object relative to a reference frame, such as a passenger on a moving train.
