Gravity in Space

Front

What is the tendency of an object to resist a change in motion called?

Back

Inertia

Front

What keeps the Earth from falling into the Sun?

Back

Earth's Inertia

Front

What happens to gravity as the distance between interacting objects decreases?

Back

Gravity increases.

Front

What are the two factors that keep a planet in orbit around the Sun?

Back

Inertia and Gravity

Front

What is a push or pull exerted on an object called?

Back

Force

Front

Define gravity in the context of space.

Back

Gravity is a force that attracts two bodies towards each other, dependent on their masses and the distance between them.

Front

What role does inertia play in the motion of planets?

Back

Inertia allows planets to continue moving in a straight line unless acted upon by another force, such as gravity.

Front

How does the mass of an object affect its gravitational pull?

Back

The greater the mass of an object, the stronger its gravitational pull.

Front

What is the relationship between mass and weight in a gravitational field?

Back

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

Front

Explain how gravity affects the motion of satellites around Earth.

Back

Gravity pulls satellites towards Earth, while their inertia keeps them moving forward, resulting in a stable orbit.
