Front

What is the amount of matter in an object called?

Back

The amount of matter in an object is called mass.

Front

What does 45 kg represent?

Back

45 kg represents mass.

Front

What happens to your weight if Earth's mass is cut in half?

Back

Your weight would decrease because gravitational force decreases.

Front

Define gravity.

Back

Gravity is the force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as weight = mass × gravitational acceleration.

Front

What is gravitational acceleration on Earth?

Back

Gravitational acceleration on Earth is approximately 9.81 m/s².

Front

How does mass affect gravitational force?

Back

The greater the mass of an object, the greater the gravitational force it exerts.

Front

What is the formula for calculating weight?

Back

Weight (W) = mass (m) × gravitational acceleration (g).
