Question

When an object moves in a fixed direction with a uniform acceleration the speed -time graph is -

Answer 1

The graph COULD look like this.

Answer 2

Hi Shashak,

◆ Answer -

When an object moves in a fixed direction with a uniform acceleration the speed-time graph is linear i.e. straight line.

◆ Uniform acceleration -

• For an object in moving with uniform acceleration, rate of change of velocity is constant.
• Speed of the object is gradually increasing with time and thus speed-time is linear i.e. straight line.
• Acceleration of an object is calculated as slope of the speed-time graph.

a = dv/dt = (v2-v1) / (t2-t1)

Hope this helps you. Thanks for asking..
