Want this question answered?
An object thrown up from the surface of the Earth exhibits ballistic or projectile motion. Actually, it doesn't matter where it's "thrown" from; any object which accelerates only due to gravity follows a curve that's a conic section. This can be a circle, an ellipse, a parabola, or a hyperbola (technically, one branch of a hyperbola) depending on its initial velocity and starting position, and all of these are considered "ballistic" trajectories.
If by motion you mean velocity it is non uniform, because the velocity is changing due the acceleration of gravity slowing it down to zero. Then at the maximum height motion is reversed and it accelerates downward back to its original speed but in the opposite direction.
A ball weighs 2.0N when placed on a scale. It is then thrown straight up.What is its weight at the very top of its motion? Explain
rolling motion occurs when a round surface (cylinder, wheel, ball) is rotating as it moves in a given direction across a surfaceslipping motion occurs when a round surface (cylinder, wheel, ball) is not rotating but sliding as it moves in a given direction across a surface
A ball rolling at a constant speed at the same rate of speed on a still surface.

projectile motion
Non uniform

A jerk ball in cricket doesn't pertain to a ball, but to the way a ball is thrown. It is the motion of the ball.
Yes, the curve ball curves. This is because of the way the ball is thrown, which is a kind of a spin/jerky fast motion.
The contact force will keep the ball moving but as the ball goes farther the ball slows down that's were the non contact force comes in it makes the ball not in contact
The motion of a ball thrown from a height, movement of a football & the movement of a hand while writtingare all examples of translatory motion.
Where when the ball is thrown it looks like a rainbow. It tips forward.

3rd law of motion i.e.action and reaction are equal and opposite
