Gravity and Inertia Review

Front

What is inertia?

Back

Inertia is the resistance of any physical object to any change in its velocity, including changes to the object's speed or direction of motion.

Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms or grams, and it remains constant regardless of location.

Front

How is weight defined?

Back

Weight is the force exerted on an object due to gravity, calculated as the product of mass and the acceleration due to gravity (W = m * g).

Front

What causes weight to vary in different locations?

Back

Weight varies in different locations due to changes in the gravitational pull, which is influenced by the mass of the celestial body and the distance from its center.

Front

What are the two primary factors that influence the force of gravity?

Back

The two primary factors that influence the force of gravity are the masses of the objects involved and the distance between their centers.

Front

What is the relationship between mass and weight?

Back

Weight is directly proportional to mass; as mass increases, weight increases, assuming the gravitational field strength remains constant.

Front

What is gravitational acceleration on Earth?

Back

Gravitational acceleration on Earth is approximately 9.81 m/s², which is the acceleration experienced by an object due to Earth's gravity.

Front

How does distance affect gravitational force?

Back

Gravitational force decreases with the square of the distance between two objects; as distance increases, the gravitational attraction decreases significantly.

Front

What is the difference between mass and weight?

Back

Mass is a scalar quantity representing the amount of matter in an object, while weight is a vector quantity that represents the gravitational force acting on that mass.

Front

What is the formula for calculating weight?

Back

The formula for calculating weight is W = m * g, where W is weight, m is mass, and g is the acceleration due to gravity.
