Gravitational Forces

Front

What is gravitational force?

Back

Gravitational force is the attraction between two objects with mass. It is a fundamental force that pulls objects toward each other, such as the Earth pulling objects toward its center.

How does mass differ from weight?

Back

Mass is the amount of matter in an object, measured in kilograms (kg), and does not change regardless of location. Weight is the force exerted by gravity on that mass, measured in newtons (N), and can change depending on the gravitational pull of the planet.

What happens to an object's weight when it moves from a planet with strong gravity to one with weak gravity?

Back

The object's weight decreases because weight is dependent on the gravitational pull of the planet.

What is the acceleration due to gravity on Earth?

Back

The acceleration due to gravity on Earth is approximately 9.8 m/s².

Front

What is terminal velocity?

Back

Terminal velocity is the constant speed an object reaches when the force of gravity is balanced by the drag force of the air, resulting in no further acceleration.

Front

Is mass the same as weight?

Back

False. Mass and weight are different; mass is a measure of matter, while weight is the force of gravity acting on that mass.

Front

What happens to the mass of an object when it is launched into space?

Back

The mass of the object remains constant regardless of its location.

Front

What is the relationship between mass and weight?

Back

Weight is calculated by multiplying mass by the acceleration due to gravity (Weight = Mass x Gravity).

Front

What is the formula for calculating weight?

Back

Weight (W) = Mass (m) x Acceleration due to gravity (g).

What is the effect of gravity on falling objects?

Back

Gravity causes falling objects to accelerate towards the ground until they reach terminal velocity.
