Objects moving in uniform circular motion will have a constant speed, and two objects with the same acceleration have a constant velocity.
false
Well, since the earth is moving, the air moves arounds the earth. So, the rotation of the earth makes air move in constant motion.
Nope, can't agree with that. "Constant motion" means constant speed in a straight line. A projectile keeps moving faster vertically downward, and its path curves downward no matter what direction you launch it. So it fails both tests for constant motion: Its speed and direction both change.
A ball moving at a constant speed around a circular track.
brownian motion
The object is in constant, uniform motion. It's moving in a straight line, and at a constant speed ... which may be zero but doesn't need to be.
Objects moving in uniform circular motion will have a constant speed, and two objects with the same acceleration have a constant velocity.
A motion with a constant speed will always be moving the same speed A motion with a constant acceleration will constantly be gaining speed, and does not remain moving at the same speed.
Newton's First Law of Motion states that an object remains at a constant velocity unless it has an unbalanced force acting upon it. That constant velocity includes zero, which means that a stationary object with no force applied to it will not move. Since velocity includes direction, then a moving object with no force applied to it will continue to move in a straight line at a constant speed.That tendency is called inertia.
"Uniform" motion means unaccelerated motion. "Unaccelerated" means moving with constant speed in a straight line.
false
When an object is moving in a uniform circular motion while traveling in a circular path, this means it has a constant speed. When an object is moving in a circular path, this indicates it is constantly being pulled towards the center of the circle.

Atoms are in constant motion. Even in a solid, the atoms are vibrating.
Any object moving in a straight line, whether at a constant speed or not, is undergoing linear motion.
