Motion Types and Description

Types of Motion

• Translational Motion: Movement from one point to another in a straight line or a curved path.
• Rotational Motion: Movement around a fixed axis, such as a wheel rotating.
• Vibrational Motion: Oscillating motion, such as a pendulum.
• Circular Motion: Movement in a circular path, such as a planet orbiting the sun.

Describing Motion

• Displacement: The shortest distance between the initial and final positions.
• Distance: The total length of the path traveled.
• Speed: The rate of change of distance with time.
• Velocity: The rate of change of displacement with time.
• Acceleration: The rate of change of velocity with time.

Motion Graphs

• Distance-Time Graphs: A graph that shows the distance traveled over time.
• Velocity-Time Graphs: A graph that shows the velocity over time.
• Acceleration-Time Graphs: A graph that shows the acceleration over time.

Equations of Motion

• v = u + at: The equation for uniformly accelerated motion, where v is the final velocity, u is the initial velocity, a is the acceleration, and t is time.
• s = ut + (1/2)at^2: The equation for the displacement of an object under uniform acceleration, where s is the displacement, u is the initial velocity, a is the acceleration, and t is time.
• v^2 = u^2 + 2as: The equation for the final velocity of an object under uniform acceleration, where v is the final velocity, u is the initial velocity, a is the acceleration, and s is the displacement.

Equations of Motion

• Uniformly accelerated motion is described by the equation v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration, and t is time.
• The displacement of an object under uniform acceleration is given by the equation s = ut + (1/2)at^2, where s is the displacement, u is the initial velocity, a is the acceleration, and t is time.
• The final velocity of an object under uniform acceleration is given by the equation v^2 = u^2 + 2as, where v is the final velocity, u is the initial velocity, a is the acceleration, and s is the displacement.
