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
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.
Earth rotating around the sun. Anything that is constantly spinning at the same rate. actually that would be an example of uniform velocity. Uniform accelerated motion is like throwing a bal off a balcony. the rock will continue to increase speed until it hits the ground. Acceleration due to gravity (-9.81m/s^2) is what makes the ball increase speed. It constantly increases speed at an equal rate
It's virtually impossible to observe an example of uniform motion where we live, i.e. on the surface of the Earth. The closest examples I've been able to think of are a puck sliding along an air-hockey table, or a bowling ball rolling down a basketball court.
If the increase in speed is uniform, this means that the slope of the function of speed over time is constant. This means that acceleration is constant.

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
