Gravity and Inertia

Front

What is inertia?

Back

Inertia is the tendency of an object to remain at rest or in uniform motion in a straight line unless acted upon by an external force.

Front

What is gravity?

Back

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

Front

How does distance affect gravitational attraction?

Back

Gravitational attraction decreases as the distance between two objects increases.

Front

What keeps the Moon in orbit around the Earth?

Back

The Moon is kept in orbit around the Earth due to the gravitational pull of the Earth.

Front

What is the relationship between mass and gravity?

Back

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

Front

What is the role of inertia in motion?

Back

Inertia helps an object resist changes to its state of motion, meaning it will continue moving in a straight line unless acted upon by a force.

Front

What is an example of inertia in everyday life?

Back

When a car suddenly stops, passengers lurch forward due to inertia.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

What is an orbit?

Back

An orbit is the curved path that an object takes around another object due to gravitational forces.

Front

What is the effect of gravity on planets?

Back

Gravity keeps planets in orbit around stars, such as the Earth orbiting the Sun.
