2023年4月22日 · The three motion graphs a high school physics student needs to know are: position vs. time (x vs. t), velocity vs. time (v vs. t), and acceleration vs. time (a vs. t). The shapes of each graph relate by slope.

Distance-time graph of an object travelling at constant speed. This general graph represents the motion of a body travelling at constant velocity. The graph is linear (that is, a straight line). Recall that linear equations have the general form. y = mx (where m is a constant and x is a variable).

2022年3月31日 · This article covers the basics for interpreting motion graphs including position-time and velocity-time graphs, how to read them, and how they are related.

Velocity-time graphs show how the velocity (or speed) of a moving object changes with time. These graphs also show if the object is moving at a constant speed or accelerating, decelerating,...

Graphs are the pictorial representation of data that is explained in the solution. Displacement time graph, velocity time graph and acceleration time graph are explained here. Time is the independent variable while displacement, acceleration and velocity are the dependent variables.

Acceleration is the rate of change of displacement with time. To find acceleration, calculate the slope in each interval. Plot these values as a function of time. Since the acceleration is constant within each interval, the new graph should be made entirely of linked horizontal segments. Displacement is the product of velocity and time.

Constant acceleration motion can be characterized by motion equations and by motion graphs. The graphs of distance, velocity and acceleration as functions of time below were calculated for one-dimensional motion using the motion equations in a spreadsheet.

A velocity-time graph shows changes in velocity of a moving object over time. The slope of a velocity-time graph represents acceleration of the moving object.

Acceleration is the time rate of change of velocity, so that can be found from the slope of a tangent to the curve on a velocity-time graph. But how could position be determined? Let's explore some simple examples and then derive the relationship.

Draw a velocity time graph for the following motion. A car brakes at traffic lights, its velocity changes from 9 m/s to rest in 6s. It remains at rest for 14s. It then accelerates to 12 m/s in 8s. Draw a set of axes for a velocity-time graph in your jotter.
