True
depends on the angle with which it is thrown, the velocity given to it.
Kinetic energy is the energy of motion; a thrown object has kinetic energy.
Projectile motion is a form of motion in which an object or particle is thrown near the earth's surface, and it moves along a curved path.

Two vectors that do not lie along the same line. I wish someone would have posted this for me. ^_^
An object thrown upward at an angle An object that's thrown horizontally off a cliff and allowed to fall
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.
This is true when the object lands at the same height as it was thrown, but not necessarity if the two are different. You can think of the motion in two parts; it moves upward and it moves sideways. If you throw it at a high angle, it won't have much of the sideways motion and won't travel far. If you throw it at a low angle, you won't have much upward motion and it will hit the ground before travelling too far. Try playing with the following simulator.look at the Related Link below for more information

yes
Projectile motion
Projectile motion is a form of motion in which an object or particle is thrown near the earth's surface, and it moves along a curved path.
In the projectile motion, when the object is thrown at angle of 45 degress, it travels the largest distance. So, in the sports like javelin throw and shot put, by throwing the spear and the iron ball, respectively, at an angle of 45 degrees, one can cover a large distance, without putting out much effort.
