This type of motion is defined as the motion of an object in which the object travels in a straight line and its velocity remains constant along that line as it covers equal distances in equal intervals of time, irrespective of the duration of the time.

What is the centre mass of a cylinder

Posted by Pixzel Gurung 4 years, 6 months ago

CBSE > Class 11 > Physics

1 answers

Sia ? 4 years, 6 months ago

If the cylinder is of uniform density, then it's at the geometric center - at the center of the circle and halfway between the ends. Because of the x*i + y*j + z*k this gives you a vector. Divide that by the total mass and the result will be a vector designating the center of mass.

Why pulling is easier than pushing

Posted by Tutu Kumar 4 years, 9 months ago

? Royal Thakur ? 4 years, 9 months ago

In case of pull or push the actual weight of the roller is same but in case of the push the sine component is in direction of the weight while in case of the pull it is in the opposite direction of the force, hence the friction force in case of push will be more than pull, so, pull will be easier than the push......
