Dynamics and kinematics are both branches of mechanics, but they focus on different aspects of motion. Kinematics deals with the description of motion, including position, velocity, and acceleration, while dynamics deals with the forces that cause motion.
The velocity of a particle can be calculated by dividing the change in position (displacement) by the change in time. This can be represented by the equation v = Δx/Δt, where v is velocity, Δx is displacement, and Δt is time.
Speed and velocity are often used interchangeably, but they have different meanings. Speed is the rate at which an object is moving, while velocity is the rate at which an object is moving in a specific direction. In other words, velocity includes both speed and direction.
Acceleration is the rate at which the velocity of a particle changes over time. When a particle experiences acceleration, its velocity either increases or decreases, depending on the direction of the acceleration. This can result in a change in the particle's speed and/or direction.
Linear motion refers to motion in a straight line, while angular motion refers to motion around a fixed point or axis. Linear motion can be described using displacement, velocity, and acceleration, while angular motion can be described using angular displacement, angular velocity, and angular acceleration.
