Understanding Center of Gravity and Torque

Why is the center of gravity important for car manufacturers?

• To improve the car's fuel efficiency

• To ensure the car's speed is maximized

• To maintain stability, especially during turns

• To reduce the car's weight

How do you find the x coordinate of an object's center of mass?

• By dividing the total mass by the sum of x coordinates

• By multiplying the mass and x coordinate of each particle, then dividing by the total mass

• By adding all x coordinates and dividing by the number of particles

• By finding the geometric center of the object

What happens if you suspend an object from its center of gravity?

• It will move in a straight line

• It will fall to the ground

• It will rotate uncontrollably

• It will balance perfectly and can rotate freely

What is torque?

• A force that causes objects to move in a straight line

• A twisting force that causes objects to spin around an axis

• A measure of an object's mass

• A type of energy stored in objects

In the example of the beam, where is the center of gravity of the system located?

• At the left end of the beam

• At the right end of the beam

• At 5 meters from the left end

• At 7.3 meters from the left end
