Velocity of the objectOn a displacement-time graph, the slope or gradient of the line represents the velocity of the object1. The steeper the line (and the greater the gradient), the faster the object is moving1. The positive gradient of the line shows that the displacement from the starting point increases at a constant rate over time, so during this period, the object is moving with a constant velocity in the positive direction2.Learn more:✕This summary was generated using AI based on multiple online sources.

In a displacement-time graph, the slope or gradient of the line, is equal to the velocity of the object. The steeper the line (and the greater the gradient) the faster the object is moving. The gradient of a displacement–time graph = velocitywww.bbc.co.uk/bitesize/guides/znpp92p/revision/4Recall that on a displacement–time graph, the gradient represents the velocity. The positive gradient of the line shows that the displacement from the starting point increases at a constant rate over time, so during this period, the object is moving with a constant velocity in the positive direction.www.nagwa.com/en/explainers/524176804562/Deformation Gradient - Continuum Mechanics
