Flashcard: Newton's Laws & Gravity 2024

Front

What does the strength of gravity between two objects depend upon?

Back

The strength of gravity depends on the mass of the objects and the distance between them.

Front

What is Newton's Third Law of Motion?

Back

Newton's Third Law states that for every action, there is an equal and opposite reaction.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

If an object has a mass of 10 kg on Earth, what is its mass on the Moon?

Back

The mass remains 10 kg on the Moon.

Front

What is the formula for calculating weight?

Back

Weight = mass × gravity (W = m × g).

Front

What is the acceleration due to gravity on Earth?

Back

The acceleration due to gravity on Earth is approximately 9.81 m/s².

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 upon by a net external force.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, which depends on its mass.

Front

How does distance affect gravitational force?

Back

As the distance between two objects increases, the gravitational force between them decreases.

Front

What is an example of Newton's Third Law in action?

Back

When a swimmer pushes the water backward, they move forward.
