Adevice that detects changes in velocity is called

Answer : Accelerometer detects the changes in velocities.

Explanation :

We know that the velocity of an object is defined as the rate of change of displacement. Velocity is a vector quantity i.e having both magnitudes as well as direction.

The rate of change of velocity of a body is called its acceleration. If u is the initial velocity and v is the final velocity of a body. Then the relation for acceleration is :

A device that detects the acceleration (changes in velocity) are Accelerometer. It finds the magnitude and direction of proper acceleration.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
