Question

True or False? (Physics) 1. Any given object will behave as if all it’s mass were concentrated at a single point called its geometric center.
2. If two objects of the same shape are resting on the same surface, the object that has the lower center gravity will be less stable than the object that has the higher center gravity.
3. If no net torqe acts upon it, a rotating top will continue to rotate. True or False? (Physics) 1. Any given object will behave as if all it’s mass were concentrated at a single point called its geometric center.

Explanation / Answer

1. TRUE as center of gravity is the point at which the whole mass of the body can be considered to be concentrated.

2. FALSE because the lower the center of gravity is, the more stable the object. The higher it is the more likely the object is to topple over if it is pushed.

3. TRUE as no net torque does not imply no rotation. It implies no change in angular momentum. If an object is already rotating this means it will continue rotating in the absence of an external torque.
