centre of mass

Which one is the measure of how much matter an object has?

• weight

• gravity

• mass

• volume

The diagram shows a uniform, flat metal sheet hanging freely from a nail at point A. One of the labelled points is at the centre of mass of the metal sheet.

Which point is at the centre of mass?

Where will be the centre of mass of a uniform rod lies ?

• At its end

• At its middle point

• At its centre of its cross sectional area

• Depends upon its material

Where the center of mass of a circle lies?

• At its centre

• Anywhere on its radius

• Anywhere on its circumference

• Anywhere on its diameter

A simple method to find centre of mass of a body is usage of

• stop watch

• plumbline

• pendulum

• gauge

Where do you hang the plumb line when determining the Centre of mass?

• It doesn't matter, because it always goes through the CG

• Only from the corners

• From the point where you are suspending the object

• At the right angle

If we suspend lamina at different positions, its centre of mass will still lie along the

• Plumb line

• Line of force

• Line of weight

• Gravity line

Center of gravity is usually located where

• more weight is concentrated

• less weight is concentrated

• less mass is concentrated

• more mass is concentrated

Center of gravity of an object depends on it's

• weight

• mass

• density

• shape

Do all objects have a centre of gravity?

• No objects have a centre of gravity

• Only some objects have a centre of gravity

• Only very heavy objects have a centre of gravity

• Yes all objects have a centre of gravity
