It is the force that keeps an object in a circular motion. Without it, Earth would move in a straight line and satellites would fall out of the sky. The lab that we have conducted is to verify the relationship that exists between the centripetal acceleration and the velocity of the object...
When considering circular motion it is often easier to work in terms of the angular velocity rather than ordinary linear velocity. Thus the poem has a circular motion corresponding to the circular shape of the object it describes. Einstein's elevator; Artillery range; Uniform acceleration and circu...

a=change in velocity/time interval = (v2δt/r)/δt=v2/r. Therefore a=v2/r also a=ω2r.a = v2/r(4) a = rω2(5) The direction of the acceleration is toward the centre O as can be seen if δt is made so that A and B all but coincide; XZ is then perpendicular to vA...
Uniform Circular Motion Main Concept Angular velocity is a quantity representing how fast an object is moving around a given fixed point called the center of rotation. When considering motion in three-dimensions, the center of rotation is no longer a...
This collection of problems focuses on the use of Newton's laws of motion and of universal gravitation to mathematically analyze situations involving circular motion or satellite motion.
Horizontal Circular Motion Recap of Centripetal Acceleration Because the speed of an object displaying circular motion is constant and tangential, circular motion produces a centripetal acceleration (acceleration directed toward the center of the circular path.) ...
Both speed and acceleration remain constant in uniform circular motion. A. True B. False Acceleration: Acceleration is a mechanical quantity that illustrates the system's speed alter in the unit time in a direction. Acceleration is measured in the unit of meter per square second, ...

A circular orbit is used for clarity here but a more general treatment of orbits and trajectories is presented in Chapter 5. We see then that this means the net radial acceleration V2/r=g. For this equilibrium condition to exist, the velocity of the vehicle V=(gr)1/2 where r=RE+z ...
