1. If a body undergoes uniformly accelerated motion, the velocity changes at a
constant rate.
2. When a vehicle’s motion is said to be uniformly accelerating, the speed is
constant throughout its motion.
3. The horizontal acceleration (ax) of a projectile is equal to 9.8 m/s2
.
4. As the projectile reaches the maximum height it momentarily stops.
5. The acceleration due to gravity is equal to zero.
6. In a bullet fired from a gun, the bullet itself is the projectile while
7. the path followed by the bullet is called the ballistic.
8. The horizontal velocity of an object thrown upward at angle remains constant.
9. A projectile is any object that has been thrown, shot, or launched.
The flight paths of all projectiles are affected by two factors: inertia and air
resistance.
10.Volleyball is a game of constant projectile motion whether it's a serve, set, or
dig, the ball will always travel in a parabolic motion.

Answer:
1. True
2. Velocity
3. Zero (0)
4. True
5. 9.8 m/s2
6. True
7. Trajectory
8. True
9. Gravity
10. True
Explanation:
that is the correct answer
thus it shows that the object i s speeding up which is influenced by a force due
to gravity and has an acceleration of -9.8 m/s2
(means 9.8 m/s2 downward).
