Gravitational Forces Between Objects

Front

What is the definition of gravitational force?

Back

Gravitational force is the attractive force between two objects with mass, which pulls them toward each other.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, measured in kilograms, while weight is the force exerted by gravity on that mass, measured in newtons.

Front

How does gravity affect the motion of objects on Earth?

Back

Gravity causes all objects to accelerate toward the Earth at approximately 9.81 m/s², regardless of their mass.

Front

What role does the Moon play in ocean tides?

Back

The Moon's gravitational force pulls on the Earth's oceans, causing the water to bulge out and create high tides.

Front

What is the atmosphere?

Back

The atmosphere is the layer of gases that surrounds the Earth, held in place by gravity.

Front

What is the formula for calculating weight?

Back

Weight can be calculated using the formula: Weight (W) = mass (m) × gravitational acceleration (g).

Front

What is the gravitational constant (G)?

Back

The gravitational constant (G) is a value used in the calculation of gravitational force between two masses, approximately equal to 6.674 × 10⁻¹¹ N(m/kg)².

Front

How does distance affect gravitational force?

Back

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

Front

What is the significance of gravitational acceleration on different planets?

Back

Gravitational acceleration varies on different planets due to their mass and radius, affecting how much an object weighs on each planet.

Front

What is the relationship between gravitational force and mass?

Back

Gravitational force is directly proportional to the product of the masses of two objects; as either mass increases, the gravitational force increases.
