Question

A body is moving in 2 dimension having acceleration in 1 dimension. Identify the motion?

Answer 1

Answer:

Explanation:

Yes.

The best example is that of a projectile motion.

When a body is projected upwards at an angle α with a velocity v then the horizontal velocity vcosα remains the same throughout the motion but the vertical velocity vsinα changes with an acceleration provided by the gravitational force.

Here the motion is a two dimensional one since the path of the trajectory is a parabola.

But acceleration of the motion is one dimensional since it always acts downwards.

Hope this helps you.
