Flashcard: Newton's Laws & Gravity 2024

Front

What is the mass of an object on the Moon if it is 6 kg on Earth?

Back

6 kg

Front

What does the strength of gravity depend on?

Back

Mass and distance between the objects.

Front

What force keeps a planet in orbit around the Sun?

Back

Gravity

Front

Which of Newton's Laws states that the harder you hit a baseball, the faster it accelerates?

Back

Newton's 2nd Law of Motion.

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is the definition of gravity?

Back

A force that attracts two bodies toward each other, proportional to their masses and inversely proportional to the square of the distance between them.

Front

How does mass affect gravitational force?

Back

The greater an object's mass, the stronger the gravitational force acting on it.

Front

What is inertia?

Back

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

Front

What is the relationship between mass and weight?

Back

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

Front

What happens to gravitational force as distance increases?

Back

Gravitational force decreases as the distance between two objects increases.
