Two graphs for motion of objects moving along a straight line are shown. State how the speed is changing with time in both cases.
Can a body have constant speed and still be accelerating ?
Write any two equations of motion for a body having uniform acceleration.
Give one example for each of the type of motion when
$(i)$ acceleration is in the direction of motion.
$(ii)$ acceleration is against the direction of motion.
$(iii)$ acceleration is uniform.
If the displacement$-$time graph for a particle is parallel to time axis, what is the velocity of the particle ?
