3. A projectile is an object upon which the only force acting is gravity. A projectile is an object upon which the only force acting is gravity. Projectiles can be thrown from all different directions Projectiles can be thrown from all different directions A projectile continues its motion by its own inertia and the downward force of gravity A projectile continues its motion by its own inertia and the downward force of gravity

5. Projectiles Projectiles go along with Newton’s First Law and his Laws of Motion saying an object will keep on doing what they are doing unless an outside force acts upon it. without without gravity the object will stay in the same motion with the same speed. For example, a projectile that is moving upwards has a downwards force acting on it and a downwards acceleration slowing it down. With the absence of forces, the object will stay in motion and go in a straight line.

6. Without gravity, the wheel will stay in motion and maintain its speed in the same direction
