Distance-Time Graph, Velocity-Time Graph

 

Distance-Time Graph

• Distance-Time graphs show the change in the position of an object with respect to time.
• Linear variation = uniform motion and non-linear variations imply non-uniform motion
• The slope gives us speed

Distance – Time Graph

• OA implies uniform motion with constant speed as the slope is constant
• AB implies the body is at rest as the slope is zero
• B to C is a non-uniform motion

Velocity-Time Graph

• Velocity-Time graphs show the change in velocity with respect to time.
• Slope gives acceleration
• The area under the curve gives displacement
• Line parallel to x-axis implies constant velocity-

Velocity – Time Graph

OA = constant acceleration, AB = constant velocity, BC = constant retardation
