Answer the following question given this paragraph: 

projectile motion: A form of motion where a particle (called a projectile) is thrown obliquely near the earth's surface, & it moves along a curved path under the action of gravity. The path followed by a projectile motion is called its trajectory. Projectile motion only occurs when there is one force applied at the beginning of the trajectory after which there is no interference apart from gravity.


Q: What type of motion only occurs when there is one force applied at the beginning of the trajectory after which there is no interference apart from gravity?

 Choices:

- velocity

- propellant

- thrust
