Flashcard: Newton's Laws & Gravity 2024

Front

What force keeps planets in orbit around the Sun?

Back

Gravity

Front

What changes as the pull of gravity changes?

Back

Weight

Front

What does Newton's First Law of Motion state?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted on by an unbalanced force.

Front

Why is the force of gravity between you and Earth greater than the force of gravity between you and a car?

Back

Because Earth has more mass than the car.

Front

What is mass?

Back

The amount of matter in an object and is constant for most objects.

Front

What is the relationship between mass and weight?

Back

Weight is the measure of the gravitational force acting on an object, which depends on its mass.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the formula for calculating force?

Back

F = ma (Force = mass x acceleration)

Front

What is gravitational force?

Back

The attractive force between two objects with mass.

Front

How does distance affect gravitational force?

Back

Gravitational force decreases as the distance between two objects increases.
