Which of the following statement is not true about projectile motion?

CHOICES:

a. Horizotal velocity of a projectile is constant

b. It is a combination of two independent motions- vertical and horizontal

c. The motion of the projectile released downward is accelerated

d. Both horizontal and vertical velocities are constant



If you have an answer please state the reason.

Thanks!Which of the following statement is not true about projectile motion?d. is wrong

horizontal velocity is always constant

vertical velocity is always not constant



the constant in vertical motion is the acceleration of gravity

but not the vertical velocityWhich of the following statement is not true about projectile motion?
All but, b.Which of the following statement is not true about projectile motion?d; vertical motion is accelerated thus velocity changesWhich of the following statement is not true about projectile motion?
D. The vertical velocity is not constant as a downward force of gravity acts on it.Which of the following statement is not true about projectile motion?Sorry, but I think it depends on the environment in which the experiment is performed.



Usually, answer D would be false.



;-D Out is space, maybe D could be true.Which of the following statement is not true about projectile motion?
A%26amp;D

Neither the horizontal or the vertical velocities are constant.

The vertical is increased by the force of gravity.

The horizontal is decreased by air resistance.

But the path of the projectile is a combination of the two.
d.Both horizontal and vertical velocities are constant is the wrong statement about projectile motion.
