Q. An object is moving in a positive direction with a positive acceleration. The velocity-time graph with constant acceleration which represents the above situation is:

Motion in a Straight Line

Solution:

The velocity-time graph formation with uniform acceleration (constant acceleration) is a straight line inclined to time axis. The above graph is for motion in positive direction as velocity is positive throughout the time interval and is also increasing, so the acceleration is positive. For positive acceleration, the slope of the graph must be positive
