KS3 Mass, weight and gravity

Front

What instrument is used to measure the weight of an object?

Back

A scale or balance is used to measure the weight of an object.

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass.

Front

What two factors affect the gravitational force between two objects?

Back

Mass and distance between the objects affect the gravitational force.

Front

What is the force of gravity acting on an object called?

Back

The force of gravity acting on an object is called its weight.

Front

Which model has greater gravitational attraction if comparing two models?

Back

The model with greater mass or closer distance will have greater gravitational attraction.

Front

What is the standard unit of weight in the metric system?

Back

The standard unit of weight in the metric system is the Newton (N).

Front

How does distance affect gravitational attraction?

Back

Gravitational attraction decreases as the distance between two objects increases.

Front

What is the gravitational force between two objects directly proportional to?

Back

The gravitational force is directly proportional to the product of their masses.

Front

What is the gravitational force between two objects inversely proportional to?

Back

The gravitational force is inversely proportional to the square of the distance between their centers.

Front

What is the weight of an object with a mass of 10 kg on Earth?

Back

The weight of an object with a mass of 10 kg on Earth is approximately 98 Newtons (using g = 9.8 m/s²).
