Straight line motion is a type of motion in which an object moves in a single direction along a straight path with constant velocity. This means that the object does not change its speed or direction as it moves.
The key components of straight line motion are distance, time, and speed. These three factors are used to calculate the motion of an object and determine its position at any given time.
The speed of an object in straight line motion is calculated by dividing the distance traveled by the time it takes to travel that distance. The formula is speed = distance/time.
Speed and velocity may seem similar, but they have different meanings in physics. Speed is a measure of how fast an object is moving, while velocity is a measure of both speed and direction. In straight line motion, an object's velocity is constant if it is moving at a constant speed in a straight line.
Straight line motion can be graphed on a distance-time graph, where the distance traveled is plotted on the y-axis and the time is plotted on the x-axis. The slope of the line on the graph represents the speed of the object, with steeper slopes indicating higher speeds.
