Question

which has a lower center of gravity a sports car or a minivan?
a minivan
a sports car
question 2
what is the point on an object where the force of gravity is considered to act?
middle of the object
center of mass
top of an object
center of gravity
question 3
true or false. the center of gravity and the center of mass are always the same in an object.
false
true

Explanation:

• Question 1: Sports cars are designed with a lower profile and have components (like engines) positioned lower to the ground, resulting in a lower center of gravity compared to minivans which are taller and have a higher mass distribution.
• Question 2: The center of gravity is defined as the point on an object where the force of gravity is considered to act. The center of mass is related but in a uniform gravitational field, for most practical purposes, the center of gravity coincides with the center of mass. However, the question is about the definition related to the force of gravity's acting point.
• Question 3: The center of gravity and center of mass are the same in a uniform gravitational field. But if the gravitational field is non - uniform (for example, over a very large object in a non - uniform gravitational environment like a huge space station near a massive celestial body), they can differ. But in most common, everyday objects on Earth (in a nearly uniform gravitational field), they are the same.

Answer:

• Question 1: B. A sports car
• Question 2: center of gravity
• Question 3: True
