Gravitational Force

What is the primary difference between mass and weight?

• Mass is a measure of an object's inertia, while weight is the force of gravity acting on an object.

• Mass changes depending on the gravitational field, while weight remains constant.

• Mass is measured in Newtons, while weight is measured in kilograms.

• Mass and weight are interchangeable terms for the same physical property.

What would a scale read if an object placed on it were in free-fall?

• The object's mass.

• Zero.

• The object's weight.

• The gravitational field strength.

An object has a mass of 0.50 kg. If the gravitational field strength is 9.8 N/kg, what is the gravitational force acting on the object?

• 4.9 N

• 0.051 N

• 19.6 N

• 9.8 N

How does gravitational field strength (g) relate to the acceleration due to gravity (g) on Earth?

• They are numerically equal but have different units.

• Gravitational field strength is always greater than acceleration due to gravity.

• They are completely unrelated concepts.

• Acceleration due to gravity is a vector, while gravitational field strength is a scalar.
