When an object is moving around in circles, there are two forces that keeps it in its circular orbit. These are the centripetal and the centrifugal forces. They are equal in magnitude, but they differ in the direction. The centripetal force is the force that pulls the object toward the circle's center. The centrifugal force is the force that pushed the object away from the circle's center.
Applying Newton's Second Law of Motions, any force is equal to its mass times its acceleration. For an object moving in circles, the force here is centrifugal or centripetal force, and the acceleration is the centripetal or centrifugal acceleration which is equal to
a = v²/r,
where v is the linear or tangential velocity
r is the radius of the circle
Applying this to Newton's Second Law of Motion,
F = mv²/r
Substituting the values,
F = (1,520 kg)(24 m/s)²/455 m
F = 1,924.22 N
The movement of stars near the center.
Answer:
The motion of a projectile is a two-dimensional motion. ... This is called the principle of physical independence of motions. The velocity of the projectile can be resolved into two mutually perpendicular components: the horizontal component and the vertical component. Acceleration changes velocity.
Explanation:
Where is the Temperature bud?
If it happens to be cruising along at 5 meters per second (about
11 miles per hour), then it covers 10 meters in 2 seconds without
any acceleration at all.
