since the balloon is moving up with a constant speed it is not accelerated or decelerated
No, it is uniformly decelerated for the first half and uniformly accelerated motion in the next half in two dimensions.
A change in the state of motion of an object indicates that a force has been applied to it. It accelerates in response, and this appears as a change in its state of motion. It may speed up, slow down, or change direction in response to the applied force.
If thrown directly upwards, it slows down due to gravitational attraction and aerodynamic drag. It reaches a maximum height and then falls. Its rate of descent is accelerated by the earth's gravity but decelerated by aerodynamic drag. If thrown at an angle, it follows a trajectory in which the vertical motion is accompanied by horizontal motion which is decelerated by aerodynamic drag.If you disregard drag, then the vertical motion is symmetrical: at any height the speed going up is exactly the same as the speed on descent. Also, for a body thrown at an angle, the trajectory is a parabola.
Constant motion has a constant speed, and accelerated motion has an accelerating speed! [getting faster] :)
The vertical component of the projectile's motion is uniformly accelerated, no matter what the angle of launch was.
The motion of molecules is accelerated.
In uniform motion, object travel at fixed and constant speed and uniformly accelerated motion the speed of the object increases uniformly.
"Non-uniform" motion is "accelerated" motion.
Yes.
Accelerated motion.
laws govern motion
Motion is said to be accelerated when its speed or direction are changing.
