Understanding Weight and Gravity

What is the formula used to calculate the weight of an object?

• f = m / g

• f = m * g

• f = g - m

• f = m + g

What is the acceleration due to gravity on Earth?

• 10.8 meters per second squared

• 9.8 meters per second squared

• 8.9 meters per second squared

• 7.8 meters per second squared

How does gravity affect objects on Earth?

• It acts on all objects regardless of their motion.

• It does not affect objects on Earth.

• It only affects objects that are moving.

• It only affects objects that are stationary.

What happens to the force of gravity as an object moves farther from Earth?

• It disappears completely.

• It increases.

• It remains constant.

• It decreases.

Why do astronauts experience weightlessness in the International Space Station?

• Because they are moving too fast.

• Because the space station is too far from Earth.

• Because they are in a free-fall orbit around Earth.

• Because there is no gravity in space.
