When you carry a heavy pail of water in your right arm Why do you tend to hold your left arm out horizontally away from your body?
When you carry a heavy load—such as a pail of water—with one arm, why do you tend to hold your free arm out horizontally? Answer: You tend to hold your free arm outstretched to shift the CG of your body away from the load so your combined CG will more easily be above the base of support.
When you whirl a can at the end of a string in a circular path What is the direction of the force you exert on the CAN group of answer choices?
It is the description of how fast a point or object on a circle or circular object is moving at a certain distance from the center. When you whirl a can at the end of a string in a circular path, what is the direction of the force you exert on the can? The force is inward towards the center. You just studied 38 terms!

Why is the linear speed greater for a horse on the outside of a merry-go-round than for a horse closer to the center 1 the horse on the outside feels less force from the Merry Go Round 2 the tangential speed of the horse is directly proportional to the distance from the center 3 the horse on the outside?
the distance from the axis of rotation. A point on the outer edge of a merry-go-round or turntable travels a greater dis- tance in one complete rotation than a point near the center. So the linear speed is greater on the outer edge of a rotating object than it is closer to the axis.

What is an example of rotation?

Why gymnasts or divers tuck in their arms and scrunch up their bodies while spinning in the air?
Ever notice how flying acrobats, gymnasts, ice-skaters and half-pipe snowboarders, tuck in their arms and scrunch up their bodies while spinning in the air? By keeping their arms and legs tucked close to their centers of mass, they are able to rotate faster.
