Center of Mass

The adjacent hoop has a diameter of 1 meter, what are the coordinates of its centre of mass

• 1,1
• 0.5,1
• 0.5,0.5
• 1,0.5

The torque of the right side of this broom is ---- the left side.

• more than
• less than
• equal to
• None of the above

The centre of mass can be located in the emptiness of the object.

• yes
• no

What is the centre of mass ?

• it is a single point at which the object can balance.
• The mass is distributed equally around it.
• the centre of gravity of the object
• All of the above

where is the centre of mass of this image

• at 20 mark
• at 42.5 mark
• at 50 mark
• at 100 mark

Which is the most likely location of the  paintbrush's center of mass?

• Location 1
• Location 2
• Location 3
• Location 4

How do we quickly find the location of an object's center of mass if it is not symmetrical?

• Use the center of mass formula.
• Find the balance point.
• You can only estimate where the center of mass is.
• The center of mass is always in the middle.

Suppose you build a glider like the one in the diagram.
The location of the center of mass of this glider is shown as a black dot.
What will happen to this glider during the stability test?

• The glider will rotate backward so that its nose tilts up.
• The glider will rotate forward so that its nose tilts downward.
• The glider will rotate sideways.
• The glider will remain stable.
