Motion

Motion is a change in position of an object with respect to time. It can be described using concepts such as distance, displacement, speed, velocity, and acceleration.

Distance and Displacement

Distance is the total length of the path traveled by an object, while displacement is the change in position of the object from its initial position to its final position. Displacement is a vector quantity, meaning it has both magnitude and direction.

Speed and Velocity

Speed is the rate at which an object covers distance, while velocity is the rate at which an object changes its displacement. Velocity is a vector quantity, and it includes the direction of the motion. The average speed is calculated by dividing the total distance traveled by the total time taken, while average velocity is calculated by dividing the total displacement by the total time taken.

Acceleration

Acceleration is the rate of change of velocity. It can be either a change in magnitude or direction, or both. The average acceleration is calculated by dividing the change in velocity by the time taken.

Study Guide
