What is curvilinear motion
What do you mean by the term curvilinear motion? State in brief?
Expert
Fundamentally, it is any motion that is made or build up by curved -- as opposed to the straight -- lines.
In high school, the curvilinear motion is generally confined to the parabolic paths traveled by objects, like a thrown ball or a bullet fired from a gun, which are moving via space in the uniform gravitational field.
