The projectile motion of an object on Earth is always _.
Correct answer: B. Parabolic
- A. Linear
- B. Parabolic
- C. Cubic
- D. Inverse
Explanation
A projectile's motion is parabolic because it is affected by gravity. Gravity causes the projectile to fall in a curved path, rather than a straight line. The equation for projectile motion takes into account the force of gravity, which is why the path of a projectile is always a parabola.

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.
