False. A person on a merry-go-round is not constantly accelerating towards the center. The person is experiencing centripetal acceleration, which is directed towards the center of the merry-go-round, but it is not a continuous increase in speed or velocity.
That's a true statement ... but not in the way you think. "Accelerating" is NOT necessarily the same thing as "speeding up".
No, in uniform circular motion, the object is accelerating because its direction is continuously changing, even though its speed remains constant. The object is accelerating toward the center of the circle, experiencing centripetal acceleration.
Centripetal means towards the center. Any object moving around in a circle is accelerating towards the center. Remember that acceleration involves a change in velocity, and a specification of "velocity" includes the direction; therefore, since the direction of the movement changes continuously, the object is "accelerating", according to the definition of acceleration.
A thought experiment: A mile high unlit black box is setting on earth. Three lit rocks are dropped from the top a few seconds apart with a sleeping astronomer (who knows nothing about his situation) on the second rock. Astronomer wakes up sees rocks 1 and 3 accelerating away from him and assumes his universe is expanding.
for every action there is a reaction equal in magnitude and opposite in direction. the Earth is pulled by the person with 500n as well but this cannot be seen because the earth 's mass is enormous.

Most galixies are micing away from each other, at a constantly accelerating pace as time passes.

Centripetal force acting on an orbiting object is unbalanced since the object is being accelerated.Velocity is continually changing direction if not speed. This means an orbiting object is accelerating and the direction of acceleration is toward the center. In fact, centripetal means "center seeking."A person at rest on the surface of the Earth is being acted upon by a centripetal force (toward the center of the Earth, that is, down) which is exactly equal and opposite to the spring force of the Earth's matter pushing up. Thus, in this case, the centripetal force is balanced.The previous answer (below) is generally incorrect.No,because when a body revolves round an orbit,its CENTRIPETAL force is balanced by the WEIGHT of the body!thank you!!
When an object travels in a circle, it is constantly changing direction, which means its velocity is also changing, even if its speed remains constant. Acceleration is defined as the rate of change of velocity, and since velocity includes both speed and direction, any change in direction constitutes acceleration. This continuous change in direction toward the center of the circle is what is known as centripetal acceleration. Therefore, an object in circular motion is always accelerating due to this constant change in direction.
As soon as he's free of the chair and out in 'space', the boy begins accelerating toward the Earth, and the Earth begins accelerating toward the boy, because of the equal, mutual forces of gravitation that attract them to each other.
A mass in outer space is either moving constantly at the speed it had when its propulsion last shut down,or else is accelerating toward another mass because of their mutual gravitational attraction.If it's accelerating toward another mass, then it continues to accelerate straight toward the centerof the other mass, either until a third mass enters the picture and the force on the object begins toinclude attraction toward two separate masses, or until it enters an atmosphere. As long as it's stillin 'outer space' and not influenced by any drag force, there is no terminal velocity.
Toward the center of mass of the object or objects attracting you. Gravity also pulls it/them toward the center of mass of you.
