Motion in a straight line is the movement of an object along a path that does not deviate from a straight line. It is a basic type of motion that is often used to describe the movement of objects in physics.
Speed is a measure of how fast an object is moving, while velocity is a measure of both the speed and direction of an object's motion. In motion in a straight line, speed can be calculated by dividing the distance traveled by the time it took to travel that distance, while velocity can be calculated by dividing the displacement (change in position) by the time it took.
Acceleration is the rate of change of an object's velocity, and it plays a role in motion in a straight line by causing a change in an object's speed or direction of motion. An object can accelerate in a straight line by either increasing or decreasing its speed, or by changing its direction of motion.
Average velocity is the total displacement divided by the total time, while instantaneous velocity is the velocity at a specific moment in time. In motion in a straight line, average velocity can be calculated using the entire distance and time of the motion, while instantaneous velocity can only be calculated at a specific point in time.
Displacement is the change in an object's position, while distance is the total length of the path traveled by an object. In motion in a straight line, displacement can be positive, negative, or zero, while distance is always positive. Displacement takes into account the direction of motion, while distance does not.
