# [Answer] An object travels in a circular path of radius r at a constant speed v. What happens to the objects acceleration if the radius of the circle is doubled and the speed stays unchanged?

###### Answer: It is cut in half
An object travels in a circular path of radius r at a constant speed v. What happens to the objects acceleration if the radius of the circle is doubled and the speed stays unchanged?

In physics circular motion is a movement of an object along the circumference of a circle or rotation along a circular path . It can be uniform with constant angular rate of rotation and constant speed or non-uniform with a changing rate of rotation. The rotation around a fixed axis of a three-dimensional body involves circular motion of its parts. The equations of motion describe the …

Fri Dec 21 2001 13:30:00 GMT-0500 (Eastern Standard Time) · Formulae. The magnitude of the centripetal force on an object of mass m moving at tangential speed v along a path with radius of curvature r is: = = = → | | where is the centripetal acceleration and is the difference between the velocity vectors. Since the velocity vectors in the above diagram have constant magnitude and since each one is perpendicular to its respective position …

In the simplest case of circular motion at radius with position given by the angular displacement () from the x-axis the orbital angular velocity is the rate of change of angle with respect to time: =.If is measured in radians the arc-length from the positive x-axis around the circle to the particle is = and the linear velocity is () = = () so that =.

The wavelength λ of a sinusoidal waveform traveling at constant speed v is given by = … For a circular aperture the diffraction-limited image spot is known as an Airy disk; the distance x in the single-slit diffraction formula is replaced by radial distance r and the sine is replaced by 2J 1 where J 1 is a first order Bessel function. The resolvable spatial size of objects viewed through …

Projectile motion is a form of motion experienced by an object or particle (a projectile) that is projected near the Earth’s surface and moves along a curved path under the action of …
