Question

What conclusion do you draw about the motion of a body from the following velocity time graphs?​

Answer 1

c) Particle comes to rest after a uniform deceleration from a certain initial velocity.

d) Particle accelerates uniformly.

e) Particle accelerates non uniformly.

f) Particle at first accelerates uniformly and then moved in constant velocity and then after a certain time, it decelerated uniformly and is now in rest.

In velocity time graphs,

• Area under graphs = Magnitude of displacement.
• Slope = $\dfrac{\Delta y}{\Delta x}$ = acceleration.
• Or tanθ = acceleratation.
• Straight inclined line graph ⇒ uniform acceleration.
• Straight vertical line (to the Y axis) = constant velocity.
