Conceptual Physics - Field Forces Review

Front

What happens to the weight of an object as it falls toward Earth?

Back

Its weight stays the same, but the force of gravity acting on it remains constant.

Front

On which planet does an astronaut weigh the most?

Back

An astronaut weighs the most on the planet with the greatest mass and gravitational pull.

Front

What is the relationship between mass and gravitational force (Fg)?

Back

As mass increases, the gravitational force (Fg) also increases.

Front

What happens to gravitational force (Fg) when mass is halved?

Back

Fg is halved (2 times smaller).

Front

What can electric force do?

Back

Electric force can attract or repel charged objects.

Front

Define weight in the context of physics.

Back

Weight is the force exerted by gravity on an object, calculated as mass times the acceleration due to gravity (W = mg).

Front

What is the formula for gravitational force (Fg) between two masses?

Back

Fg = G * (m1 * m2) / r^2, where G is the gravitational constant.

Front

How does distance affect gravitational force?

Back

Gravitational force decreases as the distance between two masses increases.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

What happens to the gravitational force if the distance between two objects is doubled?

Back

The gravitational force is reduced to one-fourth of its original value.
