Question

what is projectile motion?

Answer 1

Projectile motion is a form of motion experienced by an object or particle that is thrown near the Earth's surface and moves along a curved path under the action of gravity only. This curved path was shown by Galileo to be a parabola. 

Answer 2

Answer:

☆ if an object is given an initial velocity in any direction and then allowed to travel freely under gravity, the motion is called a projectile motion

☆ projectile motion is a form of motion experience by an object or particles that is projected near the Earth's surface and moves along a curved path under the action of gravity only.

☆ in particular, the effects of the air resistance are assumed to be negligible

☆ this curved path was shown by Galileo to be a parabola, but may also be in line the special case when it is directly upwards

☆ The study of such types of motion are called ballistics and such a trajectory is called a ballistic trajectory

☆ There are generally three types of projectile motion

● horizontal projectile motion

● oblique projectile motion

● inclined plane projectile motion

☆ The only force of significance that acts on the object gravity, which acts downward, thus imparting to the object a downward acceleration.
