Lesson 4 focuses on the use of velocity versus time graphs to describe motion. As we will learn, the specific features of the motion of objects are demonstrated by the shape and the slope of the lines …

A velocity-time graph shows how velocity changes over time. The sprinter’s velocity increases for the first 4 seconds of the race, it remains constant for the next 3 seconds, and it decreases during the …

It helps to think about the graph of speed over time rather than the graph of velocity over time. Since speed is the absolute value of velocity, you just have to take all the negative parts of the graph in the …

Key Features of a Distance-Time Graph. A flat horizontal line indicates that the object is stationary (no movement). A straight diagonal line indicates that the object is moving at a constant speed. A curved …

The speed–time graph shows that the speed decreases to zero as the ball reaches its maximum height and then increases. The velocity–time graph also shows the change in direction of the ball.

As shown in the figure, the velocity of the particle will increase linearly with respect to time. The slope of the graph will give the magnitude of acceleration.

Jan 1, 2026 · Velocity is a measure of both speed and direction of motion. A change in velocity is called acceleration. In the case of the sprinter, she accelerates as she runs down the track because her …

A horizontal line means the object is moving at a constant speed. The gradient of the line = the rate of change of speed. The steeper the line, the greater the increase in speed.

6 days ago · Its speed increases by 5 m/s every 20 s, showing that the rate at which the speed increases is constant. A speed-time graph for an object with changing positive acceleration. The time …

Jul 23, 2025 · The slope of the velocity-time graph obtained in this case is increasing in nature, the increasing slope tells that the body is in constant acceleration. The x-axis on the graph represents …
