Answer each question if it's true or false.

1. An external horizontal force maintains the horizontal velocity component of the projectile.
2. Along the horizontal axis, the projectile follows a uniformly accelerated motion.
3. The vertical motion of the projectile is similar to free-fall motion where air resistance is neglected.
4. In the absence of air resistance, all throughout the motion of the projectile the horizontal component of the velocity, the net force and the acceleration of the remain unchanged.
5. Projectile motion is a 2-dimensional motion.
6. If air resistance is neglected, then the only force acting on the projectile is the force due to gravity.
7. Along the vertical axis, the projectile follows a uniform velocity motion with acceleration equal to -9.8 m/s/s.
8. At the maximum height of the projectile, the velocity and acceleration of the projectile become zero.
9. At the maximum height, net force on the projectile is equal zero.
10. The horizontal displacement is independent of the vertical displacement of the projectile.
