Ballistics is just what it sounds like. A cannon ball was fired over and over and a statistical record was kept. Weight of the ball, powder used and cannon angle. The ball will have straight linear motion with gravity thrown in for fun. You can be traveling in a very straight forward motion, but be falling also. Newton had this all figured out.
The trajectory of the motion is a straight line.
The motion along a straight line is known as rectilinear motion.
If an object moving along a straight line,path,track etc.It,s motion is said to be straight line motion
Motion in a straight line.
no, a straight horizontal line doesn't indicates uniform motion
An object is said to be in uniform motion if it moves in a straight line at constant speed.
path traced by the body is in the form of straight line
It is due to its inertia of motion
An object in straight-line motion will continue in that motion unless acted on by another force.
Uniform motion in a straight line.
