Motion of projectile is:
Correct answer: B. Two dimensional
- A. One dimensional
- B. Two dimensional
- C. Three dimensional
- D. Four dimensional
Explanation
Projectile motion refers to the motion of an object projected into the air, like a ball thrown or a bullet shot. It involves both horizontal and vertical components of motion. The horizontal motion is uniform and unaccelerated, while the vertical motion is uniformly accelerated due to gravity. These two components are independent of each other, resulting in a two-dimensional motion. Therefore, the correct answer is that projectile motion is two-dimensional.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
