Can there be a two dimensional motion even though acceleration is present in only one direction?

Can there be motion in two dimensions with an acceleration in only one dimension?

Can there be a circular motion without acceleration?

A body is initially at rest. It Undergoes one-dimensional motion with constant acceleration. The power delivered to it at time t is proportional to(i)t(1)/2 (ii)t(iii)t(2)/3(iv) t^2

Read each statement below carefully and state with reasons and examples, if it is true or false, particle in one-dimensional motion A./with zero speed at an instant may have non-zero acceleration at that instant

The following is the distance-time table of an object in motion: What conclusion can you draw about the acceleration? Is ti constant, increasing, decreasing, or zero?

A player throws a bail upwards with an initial speed of 29.4 m s^-1 . Choose the x = 0 m and t = 0 s to be the location and time of the bail at its highest point, vertically downward direction to be the positive direction of x-axis, and give the signs of position, velocity and acceleration of the ball during its upward, and downward motion.

For a particle in one dimensional motion, the instantaneous speed is always equal to the magnitude of instantaneous velocity. Why?

A stone is thrown in a vertically upward direction with a velocity of 5 m s^1 . If the acceleration of the stone during its motion is 10m s^-2 in the downward direction, what will be the height attained by the stone and how much time will it take to reach there?
